Shell script implements whether the file is consistent across the line server _linux shell

Sometimes you need to compare files consistently in your work, and you can do it with the following script (simpler): share it, hoping to help friends with the same needs

Copy Code code as follows:

#!/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 $ '
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 $ ${@:3};
Expect {
*assword:* {send-$1\r;
Expect {
*denied* {exit 2;}
Eof
}
}
EOF {exit 1;}
}
"
# return $?
}
Num=0
For file in ' Cat $FILE ';d o
For host in ' Cat $HOST ';d o
[[$host =~ "^#"]] && continue
Let ' num++ '
if! /usr/bin/nc-w 1 $host >/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

Compared to the IP address written to host.txt, need to compare files (support multiple files) to write file.txt
The output results are:
