numpy.distutils.exec_command

exec_command

Implements exec_command function that is (almost) equivalent to commands.getstatusoutput function but on NT, DOS systems the returned status is actually correct (though, the returned status values may be different by a factor). In addition, exec_command takes keyword arguments for (re-)defining environment variables.

Provides functions:

exec_command — execute command in a specified directory and
in the modified environment.
find_executable — locate a command using info from environment
variable PATH. Equivalent to posix which command.

Requires: Python 2.x

Succesfully tested on:

os.name sys.platform comments
posix linux2 Debian (sid) Linux, Python 2.1.3+, 2.2.3+, 2.3.3 PyCrust 0.9.3, Idle 1.0.2
posix linux2 Red Hat 9 Linux, Python 2.1.3, 2.2.2, 2.3.2
posix sunos5 SunOS 5.9, Python 2.2, 2.3.2
posix darwin Darwin 7.2.0, Python 2.3
nt win32 Windows Me Python 2.3(EE), Idle 1.0, PyCrust 0.7.2 Python 2.1.1 Idle 0.8
nt win32 Windows 98, Python 2.1.1. Idle 0.8
nt win32 Cygwin 98-4.10, Python 2.1.1(MSC) - echo tests fail i.e. redefining environment variables may not work. FIXED: don’t use cygwin echo! Comment: also cmd /c echo will not work but redefining environment variables do work.
posix cygwin Cygwin 98-4.10, Python 2.3.3(cygming special)
nt win32 Windows XP, Python 2.3.3

Known bugs:

  • Tests, that send messages to stderr, fail when executed from MSYS prompt because the messages are lost at some point.
