Thanks to all the other who will respond after composing this summary, but now
I'd like to present the results I recieved so far :

   you can try this simple script I wrote, it's not a good script, but it
   served the purpose...

==============BEGIN SCRIPT===================
#!/bin/sh
xxx=$1
rm /tmp/__X.tmp 1>/dev/null 2>/dev/null
rm /tmp/___X.tmp 1>/dev/null 2>/dev/null
ps -eadf | grep "$xxx" | awk '{printf("%s %s %s %s\n",$1,$2,$6,$8)}'
>/tmp/__X.t
mp
cat /tmp/__X.tmp | grep $xxx | awk
'{printf("\t%s\t%s\t%s\t%s\n",$1,$2,$3,$4)}'
> /tmp/___X.tmp
num_user=`cat /tmp/___X.tmp | wc -l`
echo "\n"
echo "There is $num_user user using $xxx"
echo "---------------------------------------------------------"
cat /tmp/___X.tmp
echo "---------------------------------------------------------"

================END SCRIPT===================

just change the mode to executable and run it with the argument,
since I didn't put the argument checking in there... :)

example:
========

host# chmod 755 getamount
host# getamount mosaic

There is 6 user using mosaic
---------------------------------------------------------
        nobody 232 ? /mosaic2/httpd2
        root 230 ? /mosaic2/httpd2
        nobody 234 ? /mosaic2/httpd2
        nobody 235 ? /mosaic2/httpd2
        nobody 236 ? /mosaic2/httpd2
        nobody 237 ? /mosaic2/httpd2
---------------------------------------------------------
host#

You might want to try looking at a program called lsof. If it isn't
on your system you should be able to download the source for it
somewhere.

The command to list mounts doesn't really tell you who is using it with
NFS unfortunately.

The standard solution is to mv command command- ; cp command+ command

This allow people running the old executable to use the same node (mv
doesn't change that), and anybody who runs it anew gets the new copy.
That way you don't modify a running copy and confuse things.
====================================================
Sanjiv K. Bhatia wrote :

If you keep statistics on the commands that can be seen by the lastcomm
command, it will be straightforward to write the script by using things like:

        lastcomm | sort | awk '{print $1}' | uniq -c | sort -n -r

This will give you the usage count on all the commands sorted in decreasing
order of usage. To get additional information, you may have to write a short
script.

[translated and summarized]

Try : /etc/fuser [-u] dateiname1 dateiname2 ...
without the -u you'll only get the PIDs.
==========================================================
Chad Smith wrote :

This may not be the solution you are looking for, but I've found that by
writing wrapper scripts in the place of common executables, you can freely
change/remove/update those executables without the users ever knowing.
Its a somewhat rare practice, since it takes a lot of work to write the
scripts, but it works rather nifty if implemented correctly.
==============================================================
Marty Bullock wrote :

Try "fuser -u". You can probably filter the output in a script to dowhat you
want

Amaresh R. Joshi wrote :

perhaps i'm misunderstanding what you're asking, but why
can't you just use "ps", say like

alias getamount='ps -ecf | grep'

then on my system:

joshia@leech 165$ getamount ksh
   richs 11049 11047 TS 58 10:22:25 pts/1 0:00 -ksh
  joshia 11168 11166 TS 38 13:13:06 pts/0 0:00 -ksh

you could format it further if you wanted. is that
what you were asking?

// :) The formatting will do a small script, I am sure, so thanks a lot for your
// advice. I will work out your idea and tell you want I did by sending you a
// e-mail, if you want me to.

To all of you : Thanks again for your answers. As I am busy in the next three
weeks I need some time to work out all of your ideas and will summarize the
results. Even some NEW IDEAS are welcome, I will summarize them seperately if
they get too much or will summarize them with my results.

THIS LIST IS FAST AND PROFESSIONAL, I am very impressed.
