How to print /etc/passwd in different output?

eawedat · 02-06-2023, 11:20 AM

i would like to write a script that prints /etc/passwd as this output:

root daemon bin sys …
x x x x
0 1 1 2
root daemon bin sys

first line has all user accounts in same row
second line has all encrypted passwords (x) in same row
third line has all user ids in same row
and etc…

Great...we know what you would like to do. Now can you show us what you've done to accomplish your goal? We are happy to help you, but you need to show your own efforts; we aren't going to write your scripts for you, or do your homework for you.

Sorry, pet peeve: passwords in Linux are stored HASHED, not "encrypted". Two completely different things. Also, there are no passwords in /etc/passwd, the password hashes are stored in /etc/shadow.

rant over.

Bash has arrays which could be useful to solve this.
