Utilities for working with external processes.
Find absolute path to executable cmd in a cross platform manner.
This function tries to determine the full path to a command line program using which on Unix/Linux/OS X and win32api on Windows. Most of the time it will use the version that is first on the users PATH.
Warning, don’t use this to find IPython command line programs as there is a risk you will find the wrong one. Instead find those using the following code and looking for the application itself:
from IPython.utils.path import get_ipython_module_path from IPython.utils.process import pycmd2argv argv = pycmd2argv(get_ipython_module_path('IPython.terminal.ipapp'))
cmd : str
Check whether executable cmd exists or not and return a bool.
Take the path of a python command and return a list (argv-style).
This only works on Python based command line programs and will find the location of the python executable using sys.executable to make sure the right version is used.
For a given path cmd, this returns [cmd] if cmd’s extension is .exe, .com or .bat, and [, cmd] otherwise.
cmd : string
Return abbreviated version of cwd, e.g. d:mydir
