# 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.

Author: Pearu Peterson <pearu@cens.ioc.ee> Created: 11 January 2003

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.
