Question

我正在尝试编写autobuild脚本。在构建命令结束时，系统会提示用户输入密码，我想自动输入密码。我目前所拥有的是

#!/bin/bash

##stored username and password
userName = [username]
password = [password]

##connect to build server
ssh ${username]@xx.x.xx.xx

##checkout copy from svn
svn co [path of code]

##change directory to build directory
cd [build directory of checked out code]

##start build 
##expect password
/usr/bin/expect << EOF
    expect "Password: "
    spawn make build
    send ${password}
EOF

exit
echo "Build Complete"

我展示了另一种在bash脚本中执行期望的方式

expect -c \
    "set timeout -1; \
    spawn make build; \
    expect \"password: \"; \
    send -- \[password]\r\"; \
    expect eof"

在第二个例子中，[password]是一个需要密码的字符串。

当build命令提示输入密码时，它会立即生效。我尝试过其他几个例子，而spawn似乎根本不起作用。

#!/usr/bin/expect
expect "hello"
spawn echo "hello"
send "world"

直到我输入“你好”

才能做什么

任何帮助将不胜感激！

正如@chepner评论的那样，你的逻辑是错误的：你在本地机器上做了大部分工作，而不是远程工作。您需要这样的东西才能连接到远程服务器并与那里的登录shell进行交互：

#!/usr/bin/expect -f

##stored username and password
set userName "username"
set password "password"
set prompt "pattern to match user's prompt"

##connect to build server
spawn ssh $username@xx.x.xx.xx
expect -re $prompt

##checkout copy from svn
send "svn co [path of code]\r"
expect -re $prompt

##change directory to build directory
send "cd [build directory of checked out code]\r"
expect -re $prompt

##start build 
set timeout -1           ; # wait as long as required for build to finish
send "make build\r"
expect "Password: "
send -- "$password\r"

# get a prompt when build complete
expect -re $prompt
send "exit\r"
expect eof

puts "Build Complete"

期待在Bash脚本中
