Awk and Bash: Print Linux/Unix User Accounts

There are ways how to do this:

awk -F':' '{ print $1 "\t"  $3 }' /etc/passwd

That would  print the username and the UID. You can also add the sort command at the end like

awk -F':' '{ print $1 "\t"  $3 }' /etc/passwd | sort

and this will sort alphabetically.

To add filter in the result, you can

awk -F':' '$1 == "hachiko" { print $1 "\t"  $3 }' /etc/passwd | sort

where hachiko is a username you wanted to print with its UID.

Hope this helps!
