Processes by User's actual names

Hi All

I am being trained in unix and am tryin to write a script for listing the user Processes by user's names exactly the following manner WITHOUT USING A TEMPORARY FILE or SED OR AWK! The format of the output I want is:

Code:

James Hallan 
PID TTY TIME CMD 
31799 pts/3 00:00:00 vim 
31866 pts/3 00:00:00 vim 
2495 pts/7 00:00:00 vim 
8368 pts/0 00:00:00 vim 
9544 pts/2 00:00:00 ps 

Peter Anderson
PID TTY TIME CMD 
8368 pts/0 00:00:00 vim 
9544 pts/2 00:00:00 ps

So far, I have written this code and a part of the output is also shown.

Code:

echo -n > processes;

for x in $user
do



        LOGID=$x
        while IFS=: read userID junk junk junk Name junk
            do
            if [ $LOGID = $userID ];
            then
            echo "LOGID:$LOGID  Name:$Name" >> processes;
            w -s ${LOGID}|cut -c'10-200' >> processes;
            echo >> processes;
            fi
            done < /etc/passwd

done

more processes;

OUTPUT:

LOGID:james.hallan  Name:James Hallan
 up 5 days, 23:34, 46 users,  load average: 0.22, 0.28, 0.26
TTY      FROM               IDLE WHAT
pts/45   172.21.2.109      3:46  vim checking

LOGID:peter.anderson  Name:Peter Anderson
 up 5 days, 23:34, 46 users,  load average: 0.22, 0.28, 0.26
TTY      FROM               IDLE WHAT
pts/6    86.132.86.129     3:53  -bash

LOGID:laura.stewart  Name:Laura Stewart
 up 5 days, 23:34, 46 users,  load average: 0.22, 0.28, 0.26
TTY      FROM               IDLE WHAT
pts/8    172.16.1.163     52.00s vim hangman

My trainer says its not the exact same output and as you see I have used a temporary file. How can I get rid of the temporary file and get the exact same output without using SED or AWK.

The main problem I am facing is that when I use the "users" command, if a particular user is logged in from two different terminals, the output has 2 entries for that user. For eg; if james is logged in on 2 terminals, the "users" command will give print james.hallan twice on standard output. Now how do i get rid of one james.hallan entry without using sed and awk.

Secondly, how do i get the output in exactly the same format. This is very frustrating for me as I am almost there and I feel kind of helpless. Any help would be appreciated.

nice(2) 							System Calls Manual							   nice(2)

NAME

       nice - change priority of a process

SYNOPSIS

DESCRIPTION

       adds  the  value  of  priority_change to the nice value of the calling process.	A process's is a positive number for which a more positive
       value results in lower CPU priority.

       A maximum nice value of 39 and a minimum nice value of 0 are imposed by the system.  Requests for values above or below these limits result
       in the nice value being set to the corresponding limit.

       If the calling process contains more than one thread or lightweight process (i.e., the process is multi-threaded) this function shall apply
       to all threads or lightweight processes in the calling process.

   Security Restrictions
       Some or all of the actions associated with this system call are subject to compartmental restrictions. See compartments(5) for more  infor-
       mation  about  compartmentalization on systems that support that feature.  Compartmental restrictions can be overridden if the process pos-
       sesses the privilege (COMMALLOWED).  Processes owned by the superuser may not have this privilege.  Processes owned by any  user  may  have
       this privilege, depending on system configuration.

       Some  or  all  of  the  actions associated with this system call require the (OWNER) and/or the (LIMIT) privileges.  Processes owned by the
       superuser will have these privileges.  Processes owned by other users may have privilege(s), depending on system configuration.	See privi-
       leges(5) for more information about privileged access on systems that support fine-grained privileges.

RETURN VALUE

       Upon successful completion, returns the new nice value minus 20.  Otherwise, a value of -1 is returned and is set to indicate the error.

       Note that assumes a user process priority value of 20.  If a user having appropriate privileges has changed the user process priority value
       to something less than 20, certain values for priority_change can cause to return -1, which is indistinguishable from an error return.

ERRORS

       [EPERM]	      fails and does not change the nice value if priority_change is negative or greater than 40, and the effective user ID of the
		      calling process is not a user having appropriate privileges.
