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')) Parameters ---------- cmd : str The command line program to look for. scommand could not be found: %sN(R twhichtNoneR (tcmdtpath((sM/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/utils/process.pytfind_cmds cCs+yt|ƒtSWntk r&tSXdS(s?Check whether executable `cmd` exists or not and return a bool.N(RtTrueR tFalse(R((sM/data/av2000/mvv/env_mvv/lib/python2.7/site-packages/IPython/utils/process.pyt is_cmd_found7s   cCs:tjj|ƒd}|dkr)|gStj|gSdS(söTake 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. Parameters ---------- cmd : string The path of the command.
