hello

to use a ldap server, i must convert a parition of a P570, and so change id and gid of some users and groups.
So i have do this script :

# Change GID

Fich=/tmp/modgid.log
>$Fich
cp /etc/group /home/scripts/group.old

set -A tab C01sicso C01simca C01simcl C01simso C02sicso C02simca C02simcl CO2simso C03sicso C03simca C03simcl C03simso Dsidca Dsidcl Dsidso Dsirca Dsircl Dsirso adminsir admsidca admsidcl admsidso admsirso controlm dIPsidso dRCsidso dRPsidso invscout ldap mqm nagios snapp sshd sylsidca sylsidcl sylsidso tMusidca tMusidcl tMusidso tUmsidca tUmsidcl tUmsidso usrsas admsid admsirca admsircl adusrsid mdcsidca mdcsidcl mdcsidso mqbrkrs usrpilso usrpilca usrpilcl


i=600
a=0
while [ $i -le 653 ]
do
echo "i = $i" | tee -a $Fich
echo "tab a = $a" | tee -a $Fich
GRP=${tab[$a]}
echo "appartenance au groupe : $GRP" | tee -a $Fich
ID=`cat /etc/group | grep "${GRP}:" | awk -F":" '{print $3}'`
echo "Ancien GID : $ID" | tee -a $Fich
Verif=`cat /etc/group | grep "${GRP}:" | wc -c`
if [ $Verif -ge 10 ]
then
echo "Conversion !" | tee -a $Fich
chgroup id=$i ${GRP}
echo "Modification effectuee"
echo "Changement des fichiers concernes..."
find / -group ${ID} -exec chgrp $i {} \;
else
echo " Inexistant sur cette partition" | tee -a $Fich
fi
i=`expr $i + 1`
a=`expr $a + 1`
echo "--------------\n" | tee -a $Fich
done

# Change ID

Fich=/tmp/modid.log
>$Fich
cp /etc/passwd /home/scripts/passwd.old
