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.
