Simple grep script

I'm trying to write a simple script to identify every user who tried to “sudo” on the system. I have the first portion down to grep the log file

grep “sudo” /var/log/secure.

What I want to do is have the script identify the person just one time not every instance the user tried to sudo.


Thanks for your help.

NAME
mtailrc - Configuration file for monkeytail DESCRIPTION
A monkeytail configuration uses Apache-style syntax to declare "groups" of files to be tailed. Best explained with an example: <group testgroup> prefix 'server2: ' sudo yes <file> filename /var/log/apache2/access.log prefix 'server1: ' host server1.example.com </file> <file> filename /var/log/apache2/access.log host server2.example.com sudo no </file> </group> OPTIONS
All options can be either put inside a group or file block. Options inside a file block override those in the group block. filename filename filename defines the filename for this block. host remote-host (optional) host defines that this block's file is to be tailed on a remote server. sudo yes|no|1|0 sudo is a boolean specifying whether this file should be tailed as root. This option is supported for both local and remote files (in both cases you will potentially be prompted for your password). prefix "string: " prefix allows you to specify a short string that will be prepended to every line that is displayed for that given file.
