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.

Give us a small sample of the log file -- /var/log/secure.

Jim,

This is a sample of what is in the file. The only thing that changes is the sudo user, pwd and the command

sudo: pam_tally(sudo:setcred): unknown option: no_magic_root
sudo: usera : TTY=pts/2 ; PWD=/home/usera ; USER=root ; COMMAND=/bin/grep sudo /var/log/secure

Thanks.

Code:
awk ' /^sudo:/ && !arr[$2]++ '  /var/log/secure

Thanks for the suggestion - I'll give this a try when I get to work.
