expect脚本自动同步文件
#!/usr/bin/expect
set passwd "1q2w3e"
spawn rsync -av [email protected]:/tmp/12.txt /tmp/
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof
如果尝试取消最后一行，expect eof 
会出现，还没输入密码就退出的情况
/tmp目录下也没文件
指定host和要同步的文件,从本机到对方
#!/usr/bin/expect
set passwd "1q2w3e"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -av $file [email protected]$host:$file
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof
文件分发系统的实现
rsync.expect 内容
#!/usr/bin/expect
set passwd "1q2w3e"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -aRv $file [email protected]$host:$file
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof
ip.list内容
[[email protected] sbin]# cat /tmp/ip.list
192.168.67.129
192.168.67.130
127.0.0.1
file.txt内容
[[email protected] sbin]# cat /tmp/file.txt
/tmp/12.txt
/root/shell/1.sh
/root/111/222/lll.txt
rsync.sh 内容
[[email protected] sbin]# cat rsync.sh
#!/bin/bash
for ip in ‘cat /tmp/ip.list‘
do
./rsync.expect $ip /tmp/file.txt
done
出现问题，暂未解决
发现问题点，修改标点符号，即可。忘了的作用了<br/>#!/bin/bash<br/>for ip incat /tmp/ip.list` * 注意：就是这两个不是单引号的标点符号
do
./rsync.expect $ip /tmp/file.txt
done
实验结果：
[[email protected] sbin]# sh -x rsync.sh
++ cat /tmp/ip.list
- for ip in ‘
cat /tmp/ip.list‘ - ./rsync.expect 192.168.67.129 /tmp/file.txt
spawn rsync -avR --files-from=/tmp/file.txt / [email protected]:/

验证之后发现 文件同步到67.130上了
再同步一次就成功了
[[email protected] sbin]# sh -x rsync.sh

可以到67.129 67.130 验证文件是否同步过去，此处图省略。
exe.expect 执行命令
#!/usr/bin/expect
set host [lindex $argv 0]
set passwd “1q2w3e"
set cm [lindex $argv 1]
spawn ssh [email protected]$host
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect "]"
send "$cm\r"
expect "]"
send "exit\r"
#!/bin/bash
#!/bin/bash
for ip in cat /tmp/ip.list
do
./exe.expect $ip "hostname"
done
