How to use `which`?

The which command is used in Unix-like operating systems to locate the executable file associated with a command. Here's how to use it:

Basic Syntax:

which [options] command_name

Example Usage:

1. Find the path of a command:

   which python

   This will return the path to the python executable, such as /usr/bin/python.

2. Check multiple commands at once:

   which git node npm

   This will return the paths for git, node, and npm if they are installed.

Common Options:

• --help: Displays help information about the command.
• --version: Shows the version of the which command.

Note:

If the command is not found, which will not return any output.
