I want to create a user with root permision....this new user must have permision to run services and other system related tasks. can any body tell me how can I create the user with root permision.

thanks in advance

although i think this is an absolute silly idea, you can look into sudo
man sudo
for more details ...

there are a few ways...

- create another entry in your /etc/passwd file with uid 0. this is the easiest approach but it might break some software. commands like pwck will complain if you do this.

- define the exact tasks this "root" user needs to do. then update the /etc/sudoers to include this user/commands.

- define the exact tasks this "root" user needs to do. put this special user into a group (eg admin). then chgrp the commands/files he needs to access the the special group and make them suid and disable execute for others)
