thx
can u explain me how did u use that loop plz ?
I use for loop in my script. It reads the data from the "users" command. Usernames are separated by a space, so "for" will treat it as a list of items. Then I compare each item in the list with the input argument "$user".
Code:
for i in `users`; do
if [ "$i" == "$user" ]; then
found=1
break
fi
done
