Hi,
After posted many requests on how to remove user from a group, i choosed
to build my own script.
And it works very fine.
if [ $1 ] & [ $2 ]; then
cp /etc/group /tmp
cat /tmp/group | grep ^$2 > /tmp/onlygroup
cat /tmp/group | grep -v ^$2 > /tmp/nogroup
cat /tmp/onlygroup | sed "s/$1//g" | \
sed "s/ /,/g" | sed "s/,,/,/g" | sed "s/,$//g" > /tmp/newgroup
cat /tmp/newgroup >> /tmp/nogroup
cat /dev/null > /tmp/group
cat /tmp/nogroup >> /tmp/group
cp /tmp/group /etc
chmod 644 /etc/group
chown root /etc/group
chgrp wheel /etc/group
rm -f /tmp/*
echo "Success."
else
echo "Remove user from a group"
echo "Use : sh duig user group"
fi
