Hello Scrutinizer,

thanks for your quick reply. I've to give to my boss all primary group of all users from all groups where the user ONE exist.

Exemple if the user ONE exist on the GRP1 and GRP2 I have to see if there some other users in GRP1 and GRP2 and if yes, what is the primary group of thoses users.

I found that the problem come from that specific line :

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

I found that there is some exact lines two or three times.

I need a specific pattern on result as I have to give an excel file.

Thanks for your help
