工作中有时需要对比文件是否一致，通过以下脚本可以实现(比较简单)：分享出来，希望能帮助到有同样需求的朋友~

复制代码 代码如下:

#!/bin/bash

#对比服务器上文件是否一样

# Richard shen 2012/07/08

LC_ALL='en_US.UTF-8'

basedir=`dirname $0`

HOST=$basedir/host.txt

PASSWD="abcd" #密码

FILE=$basedir/file.txt

LOG=$basedir/tmp.log

>$LOG

[ ! -f /usr/bin/nc ] && yum -y install nc

[ ! -f /usr/bin/expect ] && yum -y install expect

auto_smart_ssh () {

expect -c "set timeout -1;

spawn ssh -o StrictHostKeyChecking=no $2 ${@:3};

expect {

*assword:* {send -- $1r;

expect {

*denied* {exit 2;}

eof

}

}

eof {exit 1;}

}

"

# return $?

}

num=0

for file in `cat $FILE`;do

for host in `cat $HOST`;do

[[ $host =~ "^#" ]] && continue

let 'num++'

if ! /usr/bin/nc -w 1 $host 22 > /dev/null; then

echo " ssh connect failed." | tee -a $LOG

continue

else

echo -e "e[32m$host ($FILE) MD5 compared files...e[0m"

auto_smart_ssh $PASSWD root@$host md5sum $file | grep $file | grep -v StrictHostKeyChecking | tee -a $LOG

fi

done

echo "----------------------------------------------------------"

done

对比的IP地址写入host.txt，需要对比的文件(支持多个文件)写入file.txt

输出结果为:

复制代码 代码如下:
