Hi Guys,
UID "0" means admin/full access to your Linux box. So you already know it is not a good idea to have account with 0 UID.
How to find out the accounts that are having "0" UID?
Run the script given below.
awk -F: '($3 == "0") {print}' /etc/passwd
That will give you the list of user accounts with "0" UID.
Change the UID or remove the account ASAP.
Thank you for stopping by!
