Sometimes you just want a quick way to find out if a certain user account is locked [Linux].

awk -F":" '{ print $1 }' /etc/passwd | while read UU ; do STATUS=$(passwd -S ${UU} | grep locked 2>/dev/null) ; if [[ ! -z ${STATUS} ]] ; then echo "Account ${UU} is locked." ; fi ; done

Keep it simple: cut -d: -f1 /etc/passwd | xargs -n 1 bash -c 'passwd -S "$0" &>/dev/null || echo "$0 is locked"'

Hackele, your command reports all accounts are locked because the last statement only tests for success/failure of the previous command, and the previous command will always succeed (exit status 0).

as unlocked you mean. I've never used that command before and misread the command. cut -d: -f1 /etc/passwd | xargs -n 1 bash -c 'passwd -S "$0" | cut -d\ -f2- | grep -ci l &>/dev/null && echo "$0 is locked"' My `passwd` doesn't report the word 'locked' and also the original would give false positive for the user named locked. This one seems safer provided that passwd output is compatible.

If I were to do it, I'd do getent shadow | grep ':!' | cut -d: -f1
