Suppose root user created a user say user1, and made entries in /etc/sudoers file for "user1" as "user1 ALL=(ALL) ALL". How can user1 check that he has privileges identical to root user ? Does it require to create a shell script for it ?

A user can see what he is allowed to run using sudo
by running sudo -ll
. No script is required. Below is an example:
$ sudo -ll
Matching Defaults entries for user1 on this host:
env_reset, secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin
User user1 may run the following commands on this host:
Sudoers entry:
RunAsUsers: ALL
RunAsGroups: ALL
Commands:
ALL
To check if a certain command is allowed you can use sudo -l command
. If the command is allowed the full path will be printed.
$ sudo -l ls
/bin/ls
To see what a different user is allowed to do you can add the option -U username
.

@Braiam: Yes, of course. It would be a security hazard to reveal such a sensitive information without authenticating the user. ...but if you allow the user to use
sudo
without a password (using theNOPASSWD:
directive) thensudo -ll
will not ask for a password. Nov 18, 2013 at 13:49
