Why is my GID environment variable empty?
I try echo $GID
but get nothing. However, I can get 1000 by using id -g
, what's the differences between them ?
id -u => 1000
id -g => 1000
echo $UID => 1000
echo $GID =>
The output of id
:
uid=1000(user) gid=1000(user) groups=1000(user),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),113(lpadmin),128(sambashare),999(docker)
The output of groups
:
user adm cdrom sudo dip plugdev lpadmin sambashare docker

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.
