linux expect常见用法

expect有什么用呢?

自动进行shell交互,自动填充相应信息

比如scp 拷贝文件时,需要输入密码,并且每执行一次都需要重新输入.

我觉得特别麻烦,所以写了一个自动scp的脚本,再也不需要输入密码了

#!/usr/bin/expect -f

set loginpass "123456"

set cmd_prompt "]#|~]?"
set timeout 300
set project_module "$argv"
spawn scp -r -P22  /Users/whuanghkl/work/mygit/lanproxy/proxy-${project_module}/target/proxy-${project_module}-0.0.1.jar root@123.57.78.131:/home/whuang/software/proxy-server-0.0.1/lib
 expect {
     -re "assword:" {
         send "$loginpass\r"
     } -re "Permission denied, please try again." {
        exit
     } -re "Connection refused" {
         exit
     } timeout {
        exit
     } eof {
        exit
     }
}
interact
