Smile creating a report of users using /etc/password?


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?


# 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,
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.

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