set user_in = 0
set user_date = 0
user_in=`who | grep $1 | tail -1 | awk '{printf $1}'`
user_date=`who | grep $1 | tail -1 | awk '{printf $3 " " $4 " " }'`
case $user_in in
        echo $user_date > ./out
        echo "$1 is not currently logged in"

i get the following error messages
: Command not found.
: Command not found.
case: Too many arguments.
