Linux下批量创建删除账号

1、批量创建用户

cat adduser.sh 
#!/bin/bash
#
for username in $(more users.list)
do
if [ -n $username ]
then
useradd $username -g student -d /pub/home/$username
echo
echo $username"xyz" | passwd --stdin $username
chage -d 0 $username
echo $username "has been created!"
else
echo "The username is null!"
fi
done

2、批量删除用户

cat deluser.sh 
#!/bin/bash
#
for username in $(more users.list)
do
if [ -n $username ]
then
 userdel $username
 echo
 echo $username "has been deleted!"
else
 echo "The username is null!"
fi
done

3、创建users.list，将需要批量创建的有用户填入，一行一个。
