salt.modules.cmdmod¶

A module for shelling out.

Keep in mind that this module is insecure, in that it can give whomever has access to the master root execution access to all salt minions.

salt.modules.cmdmod.exec_code(lang, code, cwd=None, args=None, **kwargs)¶

Pass in two strings, the first naming the executable language, aka - python2, python3, ruby, perl, lua, etc. the second string containing the code you wish to execute. The stdout will be returned.

All parameters from cmd.run_all except python_shell can be used.

CLI Example:

salt '*' cmd.exec_code ruby 'puts "cheese"'
salt '*' cmd.exec_code ruby 'puts "cheese"' args='["arg1", "arg2"]' env='{"FOO": "bar"}'

salt.modules.cmdmod.exec_code_all(lang, code, cwd=None, args=None, **kwargs)¶

Pass in two strings, the first naming the executable language, aka - python2, python3, ruby, perl, lua, etc. the second string containing the code you wish to execute. All cmd artifacts (stdout, stderr, retcode, pid) will be returned.

All parameters from cmd.run_all except python_shell can be used.

CLI Example:

salt '*' cmd.exec_code_all ruby 'puts "cheese"'
salt '*' cmd.exec_code_all ruby 'puts "cheese"' args='["arg1", "arg2"]' env='{"FOO": "bar"}'

salt.modules.cmdmod.has_exec(cmd)¶

Returns true if the executable is available on the minion, false otherwise

CLI Example:

salt '*' cmd.has_exec cat

salt.modules.cmdmod.powershell(cmd, cwd=None, stdin=None, runas=None, shell='/bin/sh', env=None, clean_env=False, template=None, rstrip=True, umask=None, output_encoding=None, output_loglevel='debug', hide_output=False, timeout=None, reset_system_locale=True, ignore_retcode=False, saltenv='base', use_vt=False, password=None, depth=None, encode_cmd=False, success_retcodes=None, **kwargs)¶

Execute the passed PowerShell command and return the output as a dictionary.

Other cmd.* functions (besides cmd.powershell_all) return the raw text output of the command. This function appends | ConvertTo-JSON to the command and then parses the JSON into a Python dictionary. If you want the raw textual result of your PowerShell command you should use cmd.run with the shell=powershell option.

For example:

salt '*' cmd.run '$PSVersionTable.CLRVersion' shell=powershell
salt '*' cmd.run 'Get-NetTCPConnection' shell=powershell

New in version 2016.3.0.

Warning

This passes the cmd argument directly to PowerShell without any further processing! Be absolutely sure that you have properly sanitized the command passed to this function and do not use untrusted inputs.

In addition to the normal cmd.run parameters, this command offers the depth parameter to change the Windows default depth for the ConvertTo-JSON powershell command. The Windows default is 2. If you need more depth, set that here.

Note

For some commands, setting the depth to a value greater than 4 greatly increases the time it takes for the command to return and in many cases returns useless data.

Parameters

• cmd (str) -- The powershell command to run.

• cwd (str) -- The directory from which to execute the command. Defaults to the home directory of the user specified by runas (or the user under which Salt is running if runas is not specified).

• stdin (str) -- A string of standard input can be specified for the command to be run using the stdin parameter. This can be useful in cases where sensitive information must be read from standard input.

• runas (str) -- Specify an alternate user to run the command. The default behavior is to run as the user under which Salt is running. If running on a Windows minion you must also use the password argument, and the target user account must be in the Administrators group.

• password (str) --

  Windows only. Required when specifying runas. This parameter will be ignored on non-Windows platforms.

  New in version 2016.3.0.

• shell (str) -- Specify an alternate shell. Defaults to the system's default shell.

• python_shell (bool) -- If False, let python handle the positional arguments. Set to True to use shell features, such as pipes or redirection.

• env (dict) --

  Environment variables to be set prior to execution.

  Note

  When passing environment variables on the CLI, they should be passed as the string representation of a dictionary.

  salt myminion cmd.powershell 'some command' env='{"FOO": "bar"}'
  

• clean_env (bool) -- Attempt to clean out all other shell environment variables and set only those provided in the 'env' argument to this function.

• template (str) -- If this setting is applied then the named templating engine will be used to render the downloaded file. Currently jinja, mako, and wempy are supported.

• rstrip (bool) -- Strip all whitespace off the end of output before it is returned.

• umask (str) -- The umask (in octal) to use when running the command.

• output_encoding (str) --

  Control the encoding used to decode the command's output.

  Note

  This should not need to be used in most cases. By default, Salt will try to use the encoding detected from the system locale, and will fall back to UTF-8 if this fails. This should only need to be used in cases where the output of the command is encoded in something other than the system locale or UTF-8.

  To see the encoding Salt has detected from the system locale, check the locale line in the output of test.versions_report.

  New in version 2018.3.0.

• output_loglevel (str) --

  Control the loglevel at which the output from the command is logged to the minion log.

  Note

  The command being run will still be logged at the debug loglevel regardless, unless quiet is used for this value.

• ignore_retcode (bool) -- If the exit code of the command is nonzero, this is treated as an error condition, and the output from the command will be logged to the minion log. However, there are some cases where programs use the return code for signaling and a nonzero exit code doesn't necessarily mean failure. Pass this argument as True to skip logging the output if the command has a nonzero exit code.

• hide_output (bool) --

  If True, suppress stdout and stderr in the return data.

  Note

  This is separate from output_loglevel, which only handles how Salt logs to the minion log.

  New in version 2018.3.0.

• timeout (int) -- A timeout in seconds for the executed process to return.

• use_vt (bool) -- Use VT utils (saltstack) to stream the command output more interactively to the console and the logs. This is experimental.

• reset_system_locale (bool) -- Resets the system locale

• saltenv (str) -- The salt environment to use. Default is 'base'

• depth (int) --

  The number of levels of contained objects to be included. Default is 2. Values greater than 4 seem to greatly increase the time it takes for the command to complete for some commands. eg: dir

  New in version 2016.3.4.

• encode_cmd (bool) -- Encode the command before executing. Use in cases where characters may be dropped or incorrectly converted when executed. Default is False.

• success_retcodes (list) --

  This parameter will be allow a list of

  non-zero return codes that should be considered a success. If the return code returned from the run matches any in the provided list, the return code will be overridden with zero.

  New in version 2019.2.0.

• stdin_raw_newlines (bool) --

  False

  If True, Salt will not automatically convert the characters \n present in the stdin value to newlines.

  New in version 2019.2.0.

Returns

dict

A dictionary of data returned by the powershell command.

CLI Example:

salt '*' cmd.powershell "$PSVersionTable.CLRVersion"

salt.modules.cmdmod.powershell_all(cmd, cwd=None, stdin=None, runas=None, shell='/bin/sh', env=None, clean_env=False, template=None, rstrip=True, umask=None, output_encoding=None, output_loglevel='debug', quiet=False, timeout=None, reset_system_locale=True, ignore_retcode=False, saltenv='base', use_vt=False, password=None, depth=None, encode_cmd=False, force_list=False, success_retcodes=None, **kwargs)¶

Execute the passed PowerShell command and return a dictionary with a result field representing the output of the command, as well as other fields showing us what the PowerShell invocation wrote to stderr, the process id, and the exit code of the invocation.

This function appends | ConvertTo-JSON to the command before actually invoking powershell.

An unquoted empty string is not valid JSON, but it's very normal for the Powershell output to be exactly that. Therefore, we do not attempt to parse empty Powershell output (which would result in an exception). Instead we treat this as a special case and one of two things will happen:

• If the value of the force_list parameter is True, then the result field of the return dictionary will be an empty list.

• If the value of the force_list parameter is False, then the return dictionary will not have a result key added to it. We aren't setting result to None in this case, because None is the Python representation of "null" in JSON. (We likewise can't use False for the equivalent reason.)

If Powershell's output is not an empty string and Python cannot parse its content, then a CommandExecutionError exception will be raised.

If Powershell's output is not an empty string, Python is able to parse its content, and the type of the resulting Python object is other than list then one of two things will happen:

• If the value of the force_list parameter is True, then the result field will be a singleton list with the Python object as its sole member.

• If the value of the force_list parameter is False, then the value of result will be the unmodified Python object.

If Powershell's output is not an empty string, Python is able to parse its content, and the type of the resulting Python object is list, then the value of result will be the unmodified Python object. The force_list parameter has no effect in this case.

Note

An example of why the force_list parameter is useful is as follows: The Powershell command dir x | Convert-ToJson results in

• no output when x is an empty directory.

• a dictionary object when x contains just one item.

• a list of dictionary objects when x contains multiple items.

By setting force_list to True we will always end up with a list of dictionary items, representing files, no matter how many files x contains. Conversely, if force_list is False, we will end up with no result key in our return dictionary when x is an empty directory, and a dictionary object when x contains just one file.

If you want a similar function but with a raw textual result instead of a Python dictionary, you should use cmd.run_all in combination with shell=powershell.

The remaining fields in the return dictionary are described in more detail in the Returns section.

Example:

salt '*' cmd.run_all '$PSVersionTable.CLRVersion' shell=powershell
salt '*' cmd.run_all 'Get-NetTCPConnection' shell=powershell

New in version 2018.3.0.

Warning

This passes the cmd argument directly to PowerShell without any further processing! Be absolutely sure that you have properly sanitized the command passed to this function and do not use untrusted inputs.

In addition to the normal cmd.run parameters, this command offers the depth parameter to change the Windows default depth for the ConvertTo-JSON powershell command. The Windows default is 2. If you need more depth, set that here.

Note

Warning

This function does not process commands through a shell unless the python_shell flag is set to True. This means that any shell-specific functionality such as 'echo' or the use of pipes, redirection or &&, should either be migrated to cmd.shell or have the python_shell=True flag set here.

The use of python_shell=True means that the shell will accept _any_ input including potentially malicious commands such as 'good_command;rm -rf /'. Be absolutely certain that you have sanitized your input prior to using python_shell=True

Parameters

• success_retcodes (list) --

  This parameter will be allow a list of

  New in version 2019.2.0.

• stdin_raw_newlines (bool) --

  False

  If True, Salt will not automatically convert the characters \\n present in the stdin value to newlines.

  New in version 2019.2.0.

CLI Example:

salt '*' cmd.run "ls -l | awk '/foo/{print \\$2}'"

The template arg can be set to 'jinja' or another supported template engine to render the command arguments before execution. For example:

salt '*' cmd.run template=jinja "ls -l /tmp/{{grains.id}} | awk '/foo/{print \\$2}'"

Specify an alternate shell with the shell parameter:

salt '*' cmd.run "Get-ChildItem C:\\ " shell='powershell'

A string of standard input can be specified for the command to be run using the stdin parameter. This can be useful in cases where sensitive information must be read from standard input.

salt '*' cmd.run "grep f" stdin='one\\ntwo\\nthree\\nfour\\nfive\\n'

If an equal sign (=) appears in an argument to a Salt command it is interpreted as a keyword argument in the format key=val. That processing can be bypassed in order to pass an equal sign through to the remote shell command by manually specifying the kwarg:

salt '*' cmd.run cmd='sed -e s/=/:/g'

• prepend_path (str) --

  $PATH segment to prepend (trailing ':' not necessary) to $PATH

  New in version 2018.3.0.

• template (str) -- If this setting is applied then the named templating engine will be used to render the downloaded file. Currently jinja, mako, and wempy are supported.

• rstrip (bool) -- Strip all whitespace off the end of output before it is returned.

• umask (str) -- The umask (in octal) to use when running the command.

• output_encoding (str) --

  Control the encoding used to decode the command's output.

  Note

  This should not need to be used in most cases. By default, Salt will try to use the encoding detected from the system locale, and will fall back to UTF-8 if this fails. This should only need to be used in cases where the output of the command is encoded in something other than the system locale or UTF-8.

  To see the encoding Salt has detected from the system locale, check the locale line in the output of test.versions_report.

  New in version 2018.3.0.

• output_loglevel (str) --

  Control the loglevel at which the output from the command is logged to the minion log.

  Note

  The command being run will still be logged at the debug loglevel regardless, unless quiet is used for this value.

• ignore_retcode (bool) -- If the exit code of the command is nonzero, this is treated as an error condition, and the output from the command will be logged to the minion log. However, there are some cases where programs use the return code for signaling and a nonzero exit code doesn't necessarily mean failure. Pass this argument as True to skip logging the output if the command has a nonzero exit code.

• hide_output (bool) --

  If True, suppress stdout and stderr in the return data.

  Note

  This is separate from output_loglevel, which only handles how Salt logs to the minion log.

  New in version 2018.3.0.

• timeout (int) -- A timeout in seconds for the executed process to return.

• use_vt (bool) -- Use VT utils (saltstack) to stream the command output more interactively to the console and the logs. This is experimental.

• encoded_cmd (bool) --

  Specify if the supplied command is encoded. Only applies to shell 'powershell'.

  New in version 2018.3.0.

• redirect_stderr (bool) --

  If set to True, then stderr will be redirected to stdout. This is helpful for cases where obtaining both the retcode and output is desired, but it is not desired to have the output separated into both stdout and stderr.

  New in version 2015.8.2.

• password --

  Windows only. Required when specifying runas. This parameter will be ignored on non-Windows platforms.

  New in version 2016.3.0.

• bg (bool) --

  If True, run command in background and do not await or deliver its results

  New in version 2016.3.6.

• success_retcodes (list) --

  This parameter will be allow a list of

  non-zero return codes that should be considered a success. If the return code returned from the run matches any in the provided list, the return code will be overridden with zero.

  New in version 2019.2.0.

• stdin_raw_newlines (bool) --

  False

  If True, Salt will not automatically convert the characters \n present in the stdin value to newlines.

  New in version 2019.2.0.

CLI Example:

salt '*' cmd.run_all "ls -l | awk '/foo/{print \$2}'"

The template arg can be set to 'jinja' or another supported template engine to render the command arguments before execution. For example:

salt '*' cmd.run_all template=jinja "ls -l /tmp/{{grains.id}} | awk '/foo/{print \$2}'"

A string of standard input can be specified for the command to be run using the stdin parameter. This can be useful in cases where sensitive information must be read from standard input.

salt '*' cmd.run_all "grep f" stdin='one\ntwo\nthree\nfour\nfive\n'

salt.modules.cmdmod.run_bg(cmd, cwd=None, runas=None, group=None, shell='/bin/sh', python_shell=None, env=None, clean_env=False, template=None, umask=None, timeout=None, output_encoding=None, output_loglevel='debug', log_callback=None, reset_system_locale=True, ignore_retcode=False, saltenv='base', password=None, prepend_path=None, success_retcodes=None, **kwargs)¶

Execute the passed command in the background and return its PID

Note

If the init system is systemd and the backgrounded task should run even if the salt-minion process is restarted, prepend systemd-run --scope to the command. This will reparent the process in its own scope separate from salt-minion, and will not be affected by restarting the minion service.

Parameters

• cmd (str) -- The command to run. ex: ls -lart /home

• cwd (str) -- The directory from which to execute the command. Defaults to the home directory of the user specified by runas (or the user under which Salt is running if runas is not specified).

• group (str) -- Group to run command as. Not currently supported on Windows.

• shell (str) -- Shell to execute under. Defaults to the system default shell.

• output_encoding (str) --

  Control the encoding used to decode the command's output.

  Note

  This should not need to be used in most cases. By default, Salt will try to use the encoding detected from the system locale, and will fall back to UTF-8 if this fails. This should only need to be used in cases where the output of the command is encoded in something other than the system locale or UTF-8.

• ignore_retcode (bool) -- If the exit code of the command is nonzero, this is treated as an error condition, and the output from the command will be logged to the minion log. However, there are some cases where programs use the return code for signaling and a nonzero exit code doesn't necessarily mean failure. Pass this argument as True to skip logging the output if the command has a nonzero exit code.

• runas (str) --

  Specify an alternate user to run the command. The default behavior is to run as the user under which Salt is running. If running on a Windows minion you must also use the password argument, and the target user account must be in the Administrators group.

  Warning

  For versions 2018.3.3 and above on macosx while using runas, to pass special characters to the command you need to escape the characters on the shell.

  Example:

  cmd.run_bg 'echo '\''h=\"baz\"'\''' runas=macuser
  

• password (str) --

  Windows only. Required when specifying runas. This parameter will be ignored on non-Windows platforms.

  New in version 2016.3.0.

• shell -- Specify an alternate shell. Defaults to the system's default shell.

• python_shell (bool) -- If False, let python handle the positional arguments. Set to True to use shell features, such as pipes or redirection.

• env (dict) --

  Environment variables to be set prior to execution.

  Note

  When passing environment variables on the CLI, they should be passed as the string representation of a dictionary.

  salt myminion cmd.run_bg 'some command' env='{"FOO": "bar"}'
  

• clean_env (bool) -- Attempt to clean out all other shell environment variables and set only those provided in the 'env' argument to this function.

• prepend_path (str) --

  New in version 2018.3.0.

• template (str) -- If this setting is applied then the named templating engine will be used to render the downloaded file. Currently jinja, mako, and wempy are supported.

• umask (str) -- The umask (in octal) to use when running the command.

• timeout (int) -- A timeout in seconds for the executed process to return.

Warning

This function does not process commands through a shell unless the python_shell argument is set to True. This means that any shell-specific functionality such as 'echo' or the use of pipes, redirection or &&, should either be migrated to cmd.shell or have the python_shell=True flag set here.

The use of python_shell=True means that the shell will accept _any_ input including potentially malicious commands such as 'good_command;rm -rf /'. Be absolutely certain that you have sanitized your input prior to using python_shell=True.

Parameters

• success_retcodes (list) --

  This parameter will be allow a list of

  non-zero return codes that should be considered a success. If the return code returned from the run matches any in the provided list, the return code will be overridden with zero.

  New in version 2019.2.0.

• stdin_raw_newlines (bool) --

  False

  If True, Salt will not automatically convert the characters \\n present in the stdin value to newlines.

  New in version 2019.2.0.

CLI Example:

salt '*' cmd.run_bg "fstrim-all"

The template arg can be set to 'jinja' or another supported template engine to render the command arguments before execution. For example:

salt '*' cmd.run_bg template=jinja "ls -l /tmp/{{grains.id}} | awk '/foo/{print \\$2}'"

Specify an alternate shell with the shell parameter:

salt '*' cmd.run_bg "Get-ChildItem C:\\ " shell='powershell'

If an equal sign (=) appears in an argument to a Salt command it is interpreted as a keyword argument in the format key=val. That processing can be bypassed in order to pass an equal sign through to the remote shell command by manually specifying the kwarg:

salt '*' cmd.run_bg cmd='ls -lR / | sed -e s/=/:/g > /tmp/dontwait'

Download a script from a remote location and execute the script locally. The script can be located on the salt master file server or on an HTTP/FTP server.

The script will be executed directly, so it can be written in any available programming language.

Parameters

• source (str) -- The location of the script to download. If the file is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs

• args (str) --

  String of command line args to pass to the script. Only used if no args are specified as part of the name argument. To pass a string containing spaces in YAML, you will need to doubly-quote it:

  salt myminion cmd.script salt://foo.sh "arg1 'arg two' arg3"
  

• cwd (str) -- The directory from which to execute the command. Defaults to the home directory of the user specified by runas (or the user under which Salt is running if runas is not specified).

  Specify an alternate user to run the command. The default behavior is to run as the user under which Salt is running. If running on a Windows minion you must also use the password argument, and the target user account must be in the Administrators group.

  Note

  For Window's users, specifically Server users, it may be necessary to specify your runas user using the User Logon Name instead of the legacy logon name. Traditionally, logons would be in the following format.

  Domain/user

  In the event this causes issues when executing scripts, use the UPN format which looks like the following.

  user@domain.local

• timeout (int) -- If the command has not terminated after timeout seconds, send the subprocess sigterm, and if sigterm is ignored, follow up with sigkill

• use_vt (bool) -- Use VT utils (saltstack) to stream the command output more interactively to the console and the logs. This is experimental.

• success_retcodes (list) --

  This parameter will be allow a list of

  non-zero return codes that should be considered a success. If the return code returned from the run matches any in the provided list, the return code will be overridden with zero.

  New in version 2019.2.0.

• stdin_raw_newlines (bool) --

  False

  If True, Salt will not automatically convert the characters \n present in the stdin value to newlines.

  New in version 2019.2.0.

CLI Example:

salt '*' cmd.script salt://scripts/runme.sh
salt '*' cmd.script salt://scripts/runme.sh 'arg1 arg2 "arg 3"'
salt '*' cmd.script salt://scripts/windows_task.ps1 args=' -Input c:\tmp\infile.txt' shell='powershell'

salt '*' cmd.script salt://scripts/runme.sh stdin='one\ntwo\nthree\nfour\nfive\n'

salt.modules.cmdmod.script_retcode(source, args=None, cwd=None, stdin=None, runas=None, group=None, shell='/bin/sh', python_shell=None, env=None, template='jinja', umask=None, timeout=None, reset_system_locale=True, saltenv='base', output_encoding=None, output_loglevel='debug', log_callback=None, use_vt=False, password=None, success_retcodes=None, **kwargs)¶

Download a script from a remote location and execute the script locally. The script can be located on the salt master file server or on an HTTP/FTP server.

The script will be executed directly, so it can be written in any available programming language.

The script can also be formatted as a template, the default is jinja.

Only evaluate the script return code and do not block for terminal output

Parameters

• source (str) -- The location of the script to download. If the file is located on the master in the directory named spam, and is called eggs, the source string is salt://spam/eggs

• args (str) -- String of command line args to pass to the script. Only used if no args are specified as part of the name argument. To pass a string containing spaces in YAML, you will need to doubly-quote it: "arg1 'arg two' arg3"

• cwd (str) -- The directory from which to execute the command. Defaults to the home directory of the user specified by runas (or the user under which Salt is running if runas is not specified).

• stdin (str) -- A string of standard input can be specified for the command to be run using the stdin parameter. This can be useful in cases where sensitive information must be read from standard input.

• runas (str) -- Specify an alternate user to run the command. The default behavior is to run as the user under which Salt is running. If running on a Windows minion you must also use the password argument, and the target user account must be in the Administrators group.

• password (str) --

  Windows only. Required when specifying runas. This parameter will be ignored on non-Windows platforms.

  New in version 2016.3.0.

• group (str) -- Group to run script as. Not currently supported on Windows.

• shell (str) -- Specify an alternate shell. Defaults to the system's default shell.

• python_shell (bool) -- If False, let python handle the positional arguments. Set to True to use shell features, such as pipes or redirection.

• env (dict) --

  Environment variables to be set prior to execution.

  Note

  When passing environment variables on the CLI, they should be passed as the string representation of a dictionary.

  salt myminion cmd.script_retcode 'some command' env='{"FOO": "bar"}'
  

• template (str) -- If this setting is applied then the named templating engine will be used to render the downloaded file. Currently jinja, mako, and wempy are supported.

• umask (str) -- The umask (in octal) to use when running the command.

• output_encoding (str) --

  Control the encoding used to decode the command's output.

  Note

  This should not need to be used in most cases. By default, Salt will try to use the encoding detected from the system locale, and will fall back to UTF-8 if this fails. This should only need to be used in cases where the output of the command is encoded in something other than the system locale or UTF-8.

  To see the encoding Salt has detected from the system locale, check the locale line in the output of test.versions_report.

  New in version 2018.3.0.

• output_loglevel (str) --

  Control the loglevel at which the output from the command is logged to the minion log.

  Note

  The command being run will still be logged at the debug loglevel regardless, unless quiet is used for this value.

• ignore_retcode (bool) -- If the exit code of the command is nonzero, this is treated as an error condition, and the output from the command will be logged to the minion log. However, there are some cases where programs use the return code for signaling and a nonzero exit code doesn't necessarily mean failure. Pass this argument as True to skip logging the output if the command has a nonzero exit code.

• timeout (int) -- If the command has not terminated after timeout seconds, send the subprocess sigterm, and if sigterm is ignored, follow up with sigkill

• use_vt (bool) -- Use VT utils (saltstack) to stream the command output more interactively to the console and the logs. This is experimental.

• success_retcodes (list) --

  This parameter will be allow a list of

  non-zero return codes that should be considered a success. If the return code returned from the run matches any in the provided list, the return code will be overridden with zero.

  New in version 2019.2.0.

• stdin_raw_newlines (bool) --

  False

  If True, Salt will not automatically convert the characters \n present in the stdin value to newlines.

  New in version 2019.2.0.

CLI Example:

salt '*' cmd.script_retcode salt://scripts/runme.sh
salt '*' cmd.script_retcode salt://scripts/runme.sh 'arg1 arg2 "arg 3"'
salt '*' cmd.script_retcode salt://scripts/windows_task.ps1 args=' -Input c:\tmp\infile.txt' shell='powershell'

A string of standard input can be specified for the command to be run using the stdin parameter. This can be useful in cases where sensitive information must be read from standard input.

salt '*' cmd.script_retcode salt://scripts/runme.sh stdin='one\ntwo\nthree\nfour\nfive\n'

Execute the passed command and return the output as a string.

New in version 2015.5.0.

Parameters

• cmd (str) -- The command to run. ex: ls -lart /home

• cwd (str) -- The directory from which to execute the command. Defaults to the home directory of the user specified by runas (or the user under which Salt is running if runas is not specified).

• stdin (str) -- A string of standard input can be specified for the command to be run using the stdin parameter. This can be useful in cases where sensitive information must be read from standard input.

  Warning

  For versions 2018.3.3 and above on macosx while using runas, to pass special characters to the command you need to escape the characters on the shell.

  Example:

  cmd.shell 'echo '\''h=\"baz\"'\''' runas=macuser
  

• group (str) -- Group to run command as. Not currently supported on Windows.

• password (str) --

  Windows only. Required when specifying runas. This parameter will be ignored on non-Windows platforms.

  New in version 2016.3.0.

• shell (int) -- Shell to execute under. Defaults to the system default shell.

• bg (bool) -- If True, run command in background and do not await or deliver its results

• env (dict) --

  Environment variables to be set prior to execution.

  Note

  When passing environment variables on the CLI, they should be passed as the string representation of a dictionary.

  salt myminion cmd.shell 'some command' env='{"FOO": "bar"}'
  

• clean_env (bool) -- Attempt to clean out all other shell environment variables and set only those provided in the 'env' argument to this function.

• prepend_path (str) --

  $PATH segment to prepend (trailing ':' not necessary) to $PATH

  New in version 2018.3.0.

• template (str) -- If this setting is applied then the named templating engine will be used to render the downloaded file. Currently jinja, mako, and wempy are supported.

• rstrip (bool) -- Strip all whitespace off the end of output before it is returned.

• umask (str) -- The umask (in octal) to use when running the command.

• output_encoding (str) --

  Control the encoding used to decode the command's output.

  Note

However, there are some cases where programs use the return code for signaling and a nonzero exit code doesn't necessarily mean failure. Pass this argument as True to skip logging the output if the command has a nonzero exit code.

• hide_output (bool) --

  If True, suppress stdout and stderr in the return data.

  Note

  This is separate from output_loglevel, which only handles how Salt logs to the minion log.

• timeout (int) -- A timeout in seconds for the executed process to return.

• use_vt (bool) -- Use VT utils (saltstack) to stream the command output more interactively to the console and the logs. This is experimental.

Warning

This passes the cmd argument directly to the shell without any further processing! Be absolutely sure that you have properly sanitized the command passed to this function and do not use untrusted inputs.

Parameters

• success_retcodes (list) --

  This parameter will be allow a list of

  non-zero return codes that should be considered a success. If the return code returned from the run matches any in the provided list, the return code will be overridden with zero.

  New in version 2019.2.0.

• stdin_raw_newlines (bool) --

  False

  If True, Salt will not automatically convert the characters \n present in the stdin value to newlines.

  New in version 2019.2.0.

CLI Example:

salt '*' cmd.shell "ls -l | awk '/foo/{print \$2}'"

The template arg can be set to 'jinja' or another supported template engine to render the command arguments before execution. For example:

salt '*' cmd.shell template=jinja "ls -l /tmp/{{grains.id}} | awk '/foo/{print \$2}'"

Specify an alternate shell with the shell parameter:

salt '*' cmd.shell "Get-ChildItem C:\ " shell='powershell'

A string of standard input can be specified for the command to be run using the stdin parameter. This can be useful in cases where sensitive information must be read from standard input.

salt '*' cmd.shell "grep f" stdin='one\ntwo\nthree\nfour\nfive\n'

If an equal sign (=) appears in an argument to a Salt command it is interpreted as a keyword argument in the format key=val. That processing can be bypassed in order to pass an equal sign through to the remote shell command by manually specifying the kwarg:

salt '*' cmd.shell cmd='sed -e s/=/:/g'

salt.modules.cmdmod.shell_info(shell, list_modules=False)¶

New in version 2016.11.0.

Provides information about a shell or script languages which often use #!. The values returned are dependent on the shell or scripting languages all return the installed, path, version, version_raw

Parameters

• shell (str) -- Name of the shell. Support shells/script languages include

• cmd, perl, php, powershell, python, ruby and zsh (bash,) --

• list_modules (bool) -- True to list modules available to the shell.

• only lists powershell modules. (Currently) --

Returns

A dictionary of information about the shell

Return type

dict

{'version': '<2 or 3 numeric components dot-separated>',
 'version_raw': '<full version string>',
 'path': '<full path to binary>',
 'installed': <True, False or None>,
 '<attribute>': '<attribute value>'}

Note

• installed is always returned, if None or False also returns error and may also return stdout for diagnostics.

• version is for use in determine if a shell/script language has a particular feature set, not for package management.

• The shell must be within the executable search path.

CLI Example:

salt '*' cmd.shell_info bash
salt '*' cmd.shell_info powershell
