Display or print UNIX / Linux path ~ $PATH variable

Q. How do I print current path settings under BASH shell? I’m using Debian Linux.

A. In UNIX / Linux file systems, the human-readable address of a resource is defined by PATH. On Unix / Linux like operating systems, (as well as on DOS / Windows and its descendants), PATH is an environment variable listing a set of paths to directories where executables may be found.

Display current PATH

Use echo command:
$ echo $PATH


Modify current PATH

Use export command to add /opt/games to PATH, enter:
export PATH=$PATH:/opt/games

To format your PATH variable for easy viewing, add following code to your bash startup file (such as ~/.bashrc or ~/.bash_profile) :

function path(){
    printf "%s\n" $PATH

Now just run path:
$ path
