echo "Error: NO username prefix"
exit 1
fi
del=$(grep "$prefix" /etc/passwd | cut -d: -fL | grep -v root)
if [ -z "$del"]
then
echo "No username prefix is $prefix"
else
tar zcf /root/userinfo.tar.gz -C /etc passwd shadow group gshadow &>/dev/null 做好备份
for deluser in $del
do
userdel -r $del &>/dev/null
echo user $US is delete Successfull
done
fi
