Shell Programming and Scripting

Hi guys,

I'm writing a script to display all the current logged on users and the processes they're running, output to a file. The output will look similar to this:

User1 (Real name not login name)

PID TTY TIME CMD
3179 pts/3 00:00:00 vim

User2

PID TTY TIME CMD

....etc

The users should not be displayed more than once.

So far i've got:

USERS=`finger | awk '{print $1 "\t" $2 "\n"}'`

I figure i'll use

ps -u username

but how do i take the username from $USER and apply it to the ps?

Any help greatly appreciated, as i'm just starting out with UNIX!

Thanks in advance,

Oliver

Code:

finger | nawk '!/Login/' | while read user name junk
do
    ps -fu $user
done

or

Code:

finger | while read user name junk
do
    [[ $user != Login* ]] && ps -fu $user
done

Thanks tmarikle!
There is 1 problem for each code you gave me:

1st code:
I get a 'nawk does not exist' error, changing it to awk works but i'm thinking that the nawk adds the users name above each entry?

2nd code:
the ps gets an error that the User name does not exist, but the rest still runs and i get the details i need, though again without the User's name at the top of each entry!

Also, is there an easier way to change which columns are output ie just the PID, TTY, Time and CMD or should i just stick to formatting the results after they're put into the file?

Thanks again, it's much appreciated and i'm still learning!
