script on user who logged in????
writing a script that will check every 5 seconds whether a particular user has
logged into the system Code:
# Determine if someone is logged on # Version 4.0 if [ “$#” ne 1 ] then echo “ Incorrect number of arguments” echo “Usage: $ ison4 <user>” else user=“$1” if who | grep “$user” > /dev/null then echo “$user is logged on” else echo “$user is not logged on” fi fi Last edited by Yogesh Sawant; 04-30-2008 at 02:27 AM.

I don't see the loop and the "sleep 5" but as the body of that missing loop, this looks okay (though mind-numbingly verbose -- I guess you want to take out the "is not" case once you have made sure it works correctly).

how about converting this:
Code:
echo “Usage: $ ison4 <user>” Code:
echo “Usage: $0 username”
