I assume you're using bash as your shell. Bash doesn't set a GID
variable. The list of Bash variables mentions EUID
and UID
, but not GID
.
Zsh, on the other hand, does set GID
:
$ bash -c 'echo $GID'
$ zsh -c 'echo $GID'
1000
What's the differences between usingbash -c 'echo $GID'
andecho $GID
in terminal ?

@Coreyecho $GID
in my terminal would run it in zsh, since I use zsh as my shell. In your terminal, it might be run in bash. I usebash -c ...
to run the command specifically in bash.
