shell-scripting

thers a similar question out there How can I determine whether a shellscript runs as root or not?

I have the same doubt with different result

Is it possible to, within the BASH script prior to everything being run, check if the script is being run as superuser, and if not, print a message saying You must be superuser to use this script, then subsequently

get pass from the user using askpass or something like tht then execute the saem script as superuser?
