Dear bakunin,

thanks for your quick reply.

First :

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

your right I don't need those lines.


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.

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

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

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 ; )

#!/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`
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


so here is the result as example :

user_name numeric_group_value group_name

zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
