Hi,

This is the out put of

finger omar | head -1 | awk -F":" '{print $3}'

If you do not want login name then remove the line

echo "login name: $user"

So the script will be


for user in `who | awk '{print $1}'`
do
echo ----------------
finger omar | head -1 | awk -F":" '{print $3}'
ps -u $user
echo ----------------
done

TintinCommented:
Using finger is not a reliable way of extracting the username.  For example, if you have two users called

freds - Fred Smith
johnf - John Freds

Then

finger freds

will display both users.

Better to use

grep "^$user:" /etc/passwd |cut -f5 -d:

TintinCommented:
Obviously, my above comment isn't relevant if the users are stored in NIS or LDAP.

TintinCommented:
If you do want to use finger, it's best to use:

finger -fsm $user | awk '{print $2}'

if your version of finger has the -f and -s flags, otherwise


finger -m $user | head -1 | awk -F: '{print $NF}'
