So I contact the debian-www list as indicated
It seems that there are some minor errors in the script listed in the page.
especially this line :
if [[ ${erreur_profil_inconnu} -eq 1 ]]
generates an error " sh : 1 : unknown operand"
and may be replaced by something like
if [[ "${erreur_profil_inconnu}" -eq 1 ]]
or
if [[ "$erreur_profil_inconnu" -eq 1 ]]
to make the script work properly
I have some other corrections to propose.
I'm real beginner on linux. I don't want to bother anybody, but I've adapted this script to my own needs, and some other people may have same trouble adapting it.
This article is very useful anyway.
I believe I have to login first to propose that, maybe in a page discussion ?
Thanks in advance for your help
Regards
Fred
