display the userid's of a file

ls -ln

I'm trying to display the userid's in the /etc/passwd file, but not display any other information from the file

ls lists to much information

Error
ls -n | cut -16-21,55-100 will display the userid and filename only. Just try this.

PERFECT !
better have than not to have, correct ?

I'll give you a fishing-rod not a fish, cause I believe this will help you develop your shell skills better, the good point to start would be:
man cut
man awk
have fun!

Bug
u can use either the sed or cut command

cut -d ":" -f3,5 /etc/passwd | tr ":" " "

or by using sed

sed "s/\(.*\):\(.*\):\(.*\):\(.*\):\(.*\):\(.*\)/\3 \5" /etc/passwd

will give the user id and username only.
