Linux tips and tricks - Managing your $PATH

Linux tips and tricks - Managing your $PATH

As you progress as a Linux user, expand your command line skills, and take on more complex tasks, eventually you will cross paths with $PATH (see what I did there? ;')
In fact this is true on most operating systems. The system path determines where the system looks for commands you enter. This is handy when you add new applications to the system. 
Here's a basic overview of checking and changing your $PATH to suit your needs. Be careful though. This has the potential to break your system or allow malware to break free of the standard Linux security restrictions so check into and understand any changes you make here before you make them. Also note that order matters. The system checks the path locations in the order they appear in the $PATH variable. This can cause system binaries to replaced by other binaries and break functionality etc.
