自動同步文件
#!/usr/bin/expect
set passwd "123456"
spawn rsync -av [email protected]:/tmp/12.txt /tmp/
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect eof
操作過程

20.33 構建文件分發系統
需求背景
對於大公司而言，肯定時不時會有網站或者配置文件更新，而且使用的機器肯定也是好多臺，少則幾臺，多則幾十甚至上百臺。所以，自動同步文件是至關重要的。
實現思路
首先要有一臺模板機器，把要分發的文件準備好，然後只要使用expect腳本批量把需要同步的文件分發到目標機器即可。
核心命令 rsync -av --files-from=list.txt??/??root@host:/
