  • Is your goal to find all the home directories or to print `/home/username`? For example, in standard unix, root's home directory is usually `/root`, not `/home/root`. – John1024 Aug 21 '15 at 05:56

To print /home/ before each user name:

$ awk -F: ' { print "/home/"$1 }' /etc/passwd | sort
/home/avahi
/home/backup
/home/bin
/home/clamav
/home/colord
/home/daemon
[...snip...]

If you want actual home directories, you can find them in field 6:

$ awk -F: ' { print $6 }' /etc/passwd | sort
/dev/null
/home/john1024
/nonexistent
/root

You can also access the sixth field using cut:

cut -d: -f6 /etc/passwd | sort

Printing multiple directories

As per the revised question in the comments:

$ awk -F: ' { p="/home/"$1; printf "%s\n%s\n%s\n",p"/www",p"/ftp",p"/etc" }' /etc/passwd | sort
/home/avahi/etc
/home/avahi/ftp
/home/avahi/www
/home/backup/etc
/home/backup/ftp
/home/backup/www
