TCSH / CSH Shell Set PATH Variable

by

To set the PATH environment variable in the TCSH/CSH shell, you can use the following syntax:

 
set path = (dir1 dir2 dir3 ...)

Replace dir1, dir2, dir3, etc., with the directories you want to include in the PATH. For example, to add the /usr/local/bin directory to the PATH, you can use the following command:

 
set path = ($path /usr/local/bin)

It’s important to note that the PATH variable must be set in a shell startup file, such as .cshrc or .tcshrc, in order for the changes to persist across shell sessions. To add the PATH modification to your shell startup file, simply open the file in a text editor and add the set path line to it.

After making changes to your shell startup file, you’ll need to either log out and log back in or source the file to apply the changes:

 
source ~/.cshrc

or

 
source ~/.tcshrc
