Does this answer your question? How to add a directory to the PATH? — pLumo, Apr 05 '22 at 06:05
What are you trying to achieve in the first place (See also)? Seems you want to get rid of snap, but there are better ways than changing PATH. — pLumo, Apr 05 '22 at 06:07

PATH is a colon-sepatated list of directories that your shell searches, looking for commands to execute.

Set your PATH in your ~/.bashrc by adding the following line to the end of your ~/.bashrc file:

export PATH=/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

After you save the changes to the file, run the following command in each open shell to apply the changes or simply log out and log back in:

source ~/.bashrc
