It is necessary to have superuser permissions, if you want to grep
system files and other users files. Many files under /usr and many
other directories are readable by any user and do not need 'root'
permissions.
The best approach is to use 'sudo <command>' since then only the grep
will have 'root' permissions rather than login as root.
Consider using 'find' and locate to identify files to pass to grep as
they operate much quicker and greping an entire machine will be slow as
you will scan tens of thousands of files.
