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:: import sys argv = [sys.executable, '-m', 'IPython'] Parameters ---------- cmd : str The command line program to look for.
