expect腳本自動同步文件
#!/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
如果嘗試取消最後一行，expect eof 
會出現，還沒輸入密碼就退出的情況
/tmp目錄下也沒文件
指定host和要同步的文件,從本機到對方
#!/usr/bin/expect
set passwd "1q2w3e"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -av $file root@$host:$file
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof
文件分發系統的實現
rsync.expect 內容
#!/usr/bin/expect
set passwd "1q2w3e"
set host [lindex $argv 0]
set file [lindex $argv 1]
spawn rsync -aRv $file root@$host:$file
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof
ip.list內容
[root@aminglinux01 sbin]# cat /tmp/ip.list
192.168.67.129
192.168.67.130
127.0.0.1
file.txt內容
[root@aminglinux01 sbin]# cat /tmp/file.txt
/tmp/12.txt
/root/shell/1.sh
/root/111/222/lll.txt
rsync.sh 內容
[root@aminglinux01 sbin]# cat rsync.sh
#!/bin/bash
for ip in 'cat /tmp/ip.list'
do
./rsync.expect $ip /tmp/file.txt
done
出現問題，暫未解決
發現問題點，修改標點符號，即可。忘了的作用了<br/>#!/bin/bash<br/>for ip incat /tmp/ip.list` * 注意：就是這兩個不是單引號的標點符號
do
./rsync.expect $ip /tmp/file.txt
done
實驗結果：
[root@aminglinux01 sbin]# sh -x rsync.sh
++ cat /tmp/ip.list

cat /tmp/ip.list' - ./rsync.expect 192.168.67.129 /tmp/file.txt

驗證之後發現 文件同步到67.130上了
再同步一次就成功了
[root@aminglinux01 sbin]# sh -x rsync.sh

可以到67.129 67.130 驗證文件是否同步過去，此處圖省略。
exe.expect 執行命令

set cm [lindex $argv 1]
spawn ssh root@$host
