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.

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.

Known bugs:

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