<p style="color: grey"> Python recipe 579035 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/bash/">bash</a>, <a href="/recipes/tags/commandline/">commandline</a>, <a href="/recipes/tags/commands/">commands</a>, <a href="/recipes/tags/linux/">linux</a>, <a href="/recipes/tags/shell/">shell</a>, <a href="/recipes/tags/unix/">unix</a>, <a href="/recipes/tags/utilities/">utilities</a>, <a href="/recipes/tags/which/">which</a>). </p> <p>UNIX users are familiar with the which command. Given an argument called name, it checks the system PATH environment variable, to see whether that name exists (as a file) in any of the directories specified in the PATH. (The directories in the PATH are colon-separated on UNIX and semicolon-separated on Windows.)</p> <p>This recipe shows how to write a minimal which command in Python. It has been tested on Windows.</p>
