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.
