Hi,

I need to write a script that creates a report using 25 users accounts from /etc/passwd;

I wrote the following script but it is creating a report of all the users, I just need 25 would anybody be able to help me please?

#!/bin/bash

# Grab a list of users from the /etc/passwd file

cat /etc/passwd |grep bash |grep home | awk -F: '{print $1}'

Thank you in advance!

Amber, I don't have an answer for you, but I have some advice,

Code:

grep bash /etc/password | grep home | awk -F: '{print $1}'

cat | grep is sort of "inefficient".

Hi Habitual,

I appreciate your help but your command is doing the exact same as mine, it is making a report of all users instead of just 25.

how about 'head -n 25' or 'tail -n 25'

Simply awk can do it, as:

Code:

~$ awk 'BEGIN{FS=":"}; /bash/ && /home/ {if(NR<=25) print $1}' /etc/passwd

Thnx to all for your help I appreciate it. At the end the 'tail -n' command helped me posted by mddesai, thanks for your help sir.
