this should get you a list of all the users which have been disabled  
by means of `usermod -L`:

perl -e 'open($SHADOW, "<", "/etc/shadow") or die( "$!\n" ); while ( < 
$SHADOW> ) { chomp; print "$1\n" if (/^([^:]*):!{1}[^!:]*:.*$/) }  
close( $SHADOW );'

you'll need to run it as root.  no doubt that regex could be cleaned  
up a bit :)


If this were played upon a stage now, I could condemn it as an  
improbable fiction. - Fabian, Twelfth Night, III,v
