Hi

I’m trying to loop through all logged on users and get their real names

So I came up with this script but it doesn’t work

Who > userList #save logged on users to temp file
while read username #loop through file
do
awk '{ print $1 }' | grep /etc/passwd | cut -d: -f5
done < userList

# awk '{ print $1 }' | grep /etc/passwd | cut -d: -f5 basically gets the login name from each line in userList and gets the real name from the matching line in /etc/passwd but this doesn’t work

Can someone please direct me to the right way of doing this?

I’m using bash shell

The finger command will give you real name..

man finger

Thanks, but how do I loop through each logged on users and extract their real names?

why do you have both 'grep' and 'awk AND why do you have 'FS' inside the curly braces??'

Thanks, this worked for me:

who | while read user junk
do
realname=`grep $user /etc/passwd | cut -d: -f5`
echo "User Id = $user and real name - $realname. \n"
done
