一个创建用户并且把该用户加进sshd_config的脚本，老报错求指教

黑塔之主

#!/bin/bash

file=$1
i=0
g=0
a=($(cut -d: -f3 /etc/passwd))
b=($(cut -d: -f4 /etc/passwd))
while [ ${b[$i]} ]
do
if [ ${b[$i]} -eq 100 ]
then
g=${a[$i]}
fi
i=$(($i+1))
done
#寻找gid为100的用户中，最大的uid为多少

g=$(($g+1))

for user in `cat $file`
do
useradd $user -u $g -g 100
echo "P@ssw0rd" | passwd --stdin $user
echo "$user creat success"
g=$(($g+1))
done
#新建用户里，使用的uid都为gid 100的用户里最大uid加1的值
pwconv

cp -p /etc/ssh/sshd_config /etc/ssh/sshd_config.`date +%Y%m%d`
for user in `cat $file`
do
sed -i '/^AllowUsers/s/$/ $user/' /etc/ssh/sshd_config
done
service sshd restart






用该方式执行脚本
sudo ./array.sh $HOME/user
Changing password for user Snonk.
passwd: all authentication tokens updated successfully.
Snonk creat success
Changing password for user Talkash.
passwd: all authentication tokens updated successfully.
Talkash creat success
Changing password for user Thalaniya.
passwd: all authentication tokens updated successfully.
Thalaniya creat success
'/array.sh: line 32: syntax error near unexpected token `do
'/array.sh: line 32: `do

想请教一下各位高手，为什么会报错32行的do有问题，麻烦了。

我运行正常啊

useradd: user 'aa' already exists
Changing password for user aa.
passwd: all authentication tokens updated successfully.
aa creat success
useradd: user 'bb' already exists
Changing password for user bb.
passwd: all authentication tokens updated successfully.
bb creat success
useradd: user 'cc' already exists
Changing password for user cc.
passwd: all authentication tokens updated successfully.
cc creat success
useradd: user 'dd' already exists
Changing password for user dd.
passwd: all authentication tokens updated successfully.
dd creat success
useradd: user 'ee' already exists
Changing password for user ee.
passwd: all authentication tokens updated successfully.

cp -p /etc/ssh/sshd_config /etc/ssh/sshd_config.`date +%Y%m%d`
for user in `cat $file`
do
sed -i '/^AllowUsers/s/$/ $user/' /etc/ssh/sshd_config
done
service sshd restart

想问下，运行这段代码也没问题么

没问题

-rw-------  1 root root   3879 Jan 27 06:10 sshd_config.20150416

我是一隻羊

cat -A urscript一下试试?

已经解决了，只是不知道是什么回事。
把原代码删掉，把论坛的复制过去就解决了。
