List users in Linux

Question

How can I list in alphabetical order all users and also for the first 10 users to see user ID info (column 5). I know for the first part of the question that I can use like cat /etc/passwd | cut -d ':' -f1, but how about the second part? should i use "for" or "if" or something like this?

Answer 1

Remove the header with grep and use cut:

cat /etc/passwd | grep -v '^#' | cut -d: -f1,5
