Parameters

string

The command to execute.

Returns

If string is null, system will return a non-zero value if the command interpreter sh(1) is available, and zero if it is not.

Otherwise, the system function returns the exit status of the shell as returned by Syscall.waitpid(2), or -1 if an error occurred when invoking Syscall.fork(2) or Syscall.waitpid(2). A return value of 127 means the execution of the shell failed.
