I want to set a shell variable for the output of a following command :

basename $(realpath $DIR)   //$DIR is a softlink

when I do :

set FOLDER_NUM=$(basename $(realpath $DIR))

and source the script , it says :

Illegal variable name.

Im expecting to get the folder name of realpath of $DIR into FOLDER_NUM variable .

example :

$DIR is "/usr/kate/latest"
realpath $DIR

will give /usr/kate/12134

I want to set FOLDER_NUM=12134

You don't use `set` to assign variables. It's just `variable=` – Barmar May 08 '23 at 21:06

`$DIR = "/usr/kate/latest"` is not correct bash code. It looks more like PHP. – Barmar May 08 '23 at 21:20
I meant $DIR is /usr/kate/latest – Sahith .A May 09 '23 at 03:36
