Locked users

[lycan]

I have found users on my linux machine by using command.

# egrep -v '.*:\*|:\!' /etc/shadow | awk -F: '{print $1}'

then i locked some of users which were not required.
Now how to find list of users which are locked .

i tried a command for this

# passwd -S -a | grep " L " | cut -d " " -f1
but it respond as

passwd: bad argument -a: unknown option



how to find list of locked users ?? please sought a way to this..

Possibly because there no -a option for the passwd command?

[nujinini]

egrep -v '.*:\*|:\!' /etc/shadow | awk -F: '{print $1}'

Can somebody please explain this?
