But you can confirm this with a simple command: echo $0 Not sure which shell you're running? If you're using pretty much any common Linux distribution, and haven't changed the defaults, chances are you're running Bash.
The exact way to do this depends on which shell you're running. The variable $PATH is set by your shell every time it launches, but you can set it so that it always includes your new path with every new shell you open. Set your PATH permanentlyīut what happens if you restart your computer or create a new terminal instance? Your addition to the path is gone! This is by design.

You should now be able to execute the script anywhere on your system by just typing in its name, without having to include the full path as you type it. Simply add /place/with/the/file to the $PATH variable with the following command: export PATH= $PATH: /place /with /the / file This script provides some useful function to all of the files in your current directory, that you'd like to be able to execute no matter what directory you're in. Let's say you wrote a little shell script called hello.sh and have it located in a directory called /place/with/the/file. Now let's add another directory to the list. You'll probably see the directories mentioned above, as well as perhaps some others, and they are all separated by colons. To see what's in your $PATH right now, type this into a terminal: echo $PATH You can do this easily by adding a directory to your $PATH.

Sometimes, you may wish to install programs into other locations on your computer, but be able to execute them easily without specifying their exact location. How does it know to look in the directories mentioned above? It's simple: They are a part of an environment variable, called $PATH, which your shell checks in order to know where to look. When you type a command into your Linux shell, it doesn't look in every directory to see if there's a program by that name.
