[sudo-users] How to use sudo without typing sudo before any command

[Vijay Lad]

Hi All,
      I am very new user for sudo, I have install the sudo on my centos &
its working fine. The problem is that, I have to enter sudo before running
any command. Is ther any way where I can enter sudo at start & after that I
can run any command without typing sudo before command?

Please reply.

Thanks,

Vijay
