Sooner or later, you are going to wish to run instructions from non-standard directories. When that occurs, you may wish to add these directories to your $PATH. Jack Wallen reveals you ways.
Your Linux PATH is the way you outline the directories for which instructions will be run globally. In different phrases, when you’ve got an executable file in a listing that’s configured to be in your PATH, you may run that executable from wherever within the Linux file construction. That is what makes it doable to run instructions in /usr/bin from your private home listing (or wherever, for that matter).

Out of the field, the Linux PATH incorporates the same old entries, reminiscent of /usr/bin/, /usr/sbin/, /usr/native/bin, and so forth. However what occurs when you’ve got a non-standard listing from which you want to have the ability to execute instructions? That is when you need to manually add these directories to the PATH.
How do you do this? Let me present you.
As an instance you’ve gotten a listing known as SCRIPTS in your house listing. Let’s add that to the PATH.
- Log into your Linux machine and open a terminal window.
- Open your .bashrc file for enhancing with the command nano ~/.bashrc.
- Scroll to the underside of that file and add the next: PATH=”~/SCRIPTS:$PATH”.
It is crucial to incorporate the $PATH portion, as that makes certain the usual directories stay in your path (in any other case, the one listing in your PATH could be SCRIPTS and that will not be good).
- Save and shut the file.
- Shut and reopen the terminal.
At this level, you may run any executable, discovered within the SCRIPTS listing, from wherever within the filesystem hierarchy.

And that is the way you add new directories to your PATH. This little trick will are available in very useful, particularly while you begin writing your individual bash scripts that you do not wish to be saved in frequent directories.
