Recently 2 out of 3 of the server raid hdd went dead, so I need to setup a replacement server real quick. One of the dilemma I am facing is needing to recreate all user accounts. My eyes are already too tired to look through the /etc/passwd file. Since I only need to list out alll users except the system account so I just use the command below:

awk -F: ‘{if ($3>=500 && $3<=1000) print $1}’ /etc/passwd

You can also make it as shell script if you need to use that on the regular basis.
