Whether you’re moving around the file system, looking for files or trying to move into important directories, Linux can provide a lot of help. In this post, we’ll look at a number of tricks to make moving around the file system and both finding and using commands that you need a little easier.
One of the easiest and most useful ways to ensure that you don’t have to invest a lot of time into finding commands on a Linux system is to add the proper directories to your $PATH variable. The order of directories that you add to your $PATH variable is, however, very important. They determine the order in which the system will look through the directories to find the command to run — stopping when it finds the first match.
