awk user name and name from passwd

[MarkSyder]

Hi everybody,

I'm trying to produce a list of users from the passwd file. The only info I want to extract is user id and name (fields 1 and 5). I've tried the following:

for i in `cat passwd|awk -F: '{print $1, $5}'`
do
echo $i >> newfile
done

but the user id and name always end up on different lines. I've tried putting \c and "\c" inbetween the $1 and $5 but it has not had any effect.

Any ideas?

cat /etc/passwd | awk -F ":" '{print $1,$5}'

cut -f1,5 -d":" /etc/passwd >> newfile


Will do it

cat /etc/passwd|while read line
do
echo $line|awk -F: '{print $1, $5}' >> newfile
done

10 out of 10 Karthik! But 0 out of 10 for the person who wrote the manual I'm working from.

Steve - Karthik's solution worked, so I didn't try yours. Three points to acknowledge the fact that you tried to help.

This thread is now closed as it is working perfectly.

I know the thread is closed, but just for
reference, you don't need to use `cat`:

awk -F":" '{print $1,$5}' /etc/passwd

By any chance do you still believe in Santa?

How about:

logins

The formatting is already done for you and there are a plethora of options including the very useful -d to locate duplicate user ID's.

The thread may have been closed, but reducing the amount of typing I do merits some thanks - Santa Syder is going to give more points.

Sorry, but asking someone if they still believe in Santa (or Father Christmas as we call him in this country) does not qualify for points!

Bill - logins would have reduced my typing still further, but I tried it twice and it caused a core dump both times.

Oh, oh. I'd check on patches but also run pwck to see if /etc/passwd is OK. logins has been around for a long time and works on Trusted and unTrusted alike.
