Dear bakunin,

thanks for your quick reply.

First :

Code:
\rm ${fic_ListGRP_tmp.log}
\rm ${fic_ListUSR_tmp.log}

your right I don't need those lines.

Then

I am on solaris 9. I also believed the line code below is not good as there is two or three times the exact same lines with the same users. This why my result log contains more users than I have if I am making manually the print screen of the command. I belived the for loop can't work as I need.

Code:
cat /etc/group | grep ${groupe} | awk 'BEGIN{FS=":"} {print $4}' | sed 's/,/ /g'

I hope you may be help me to make it right.

Thanks

Dear Friends,

thanks a lot for your help. I solved my problem. Sorry for making all of you searching to help me. I am so glad to have you for help.

My problem was my brain ; )

Code:
#!/bin/ksh -p

touch fic_ListUSR_tmp.log
touch fic_results_tmp.log

cat /etc/group | grep ONE | awk 'BEGIN{FS=":"} {print $4}' | sed 's/,/ /g' > fic_ListUSR_tmp.log
for user in `cat fic_ListUSR_tmp.log`
do
group_prim=`cat /etc/passwd | grep $user: | awk 'BEGIN{FS=":"}{print $4}' | head -1`
name_groupe=`cat /etc/group | grep ":$group_prim:" | awk 'BEGIN{FS=":"}{print $1}'`
echo "$user $group_prim $name_groupe" | tee -a >> fic_results_tmp.log


done

so here is the result as example :

user_name numeric_group_value group_name

thanks

NAME

       groups - Displays your group membership

SYNOPSIS

       groups [user]

DESCRIPTION

       The  groups command writes to standard output the groups to which you or the specified user belong.  The Tru64 UNIX operating system allows
       a user to belong to many different groups at the same time.

       Your primary group is specified in the /etc/passwd file. Once you are logged in, you can change your active group  with	the  newgrp  shell
       command (see sh). When you create a file, its group ID is that of your active group.

       Other groups that you belong to are specified in the /etc/group file.  If you belong to more than one group, you can access files belonging
       to any of those groups without changing your primary group ID.  These are called your concurrent groups.

NOTES

       The /etc/passwd and /etc/group files must be on the same node.

EXAMPLES

       To determine your group membership, enter: groups

       The groups to which you belong will be displayed.  For example: devel  prod

FILES

       Contains group information.  Contains user information.
