为Linux "adduser“命令创建Expect脚本

Question

说到期待，我是个新手，我想我会先在我的本地机器上试用Expect，这样我就会把脚弄湿了。

为此，我想我应该尝试针对"adduser“命令运行Expect。

我无法使它正常工作，似乎一切都在正常运行，我能够到达最后一个提示，并且它确实退出了，但是用户仍然没有创建。

我做错了什么？

#/usr/bin/expect -f 
spawn adduser testuser

expect "Enter new UNIX password"
send "testpassword\r"

expect "Retype new UNIX password"
send "testpassword\r"

expect "        Full Name []: "
send "\r"

expect "        Room Number []: "
send "\r"

expect "        Work Phone []: "
send "\r"

expect "        Home Phone []: "
send "\r"

expect "        Other []: "
send "\r"

expect "Is the information correct? \[Y/n\] "
send "\r"

Answer 1

将以下内容保存为“automateUser”。chmod 775。然后在命令行上。

数独期待-d automateUser

#!/usr/bin/expect

spawn adduser testuser

expect "Enter new UNIX password" { send "testpass\r" }
expect "Retype new UNIX password" { send "testpass\r" }
expect "Full Name" { send "\r" }
expect "Room Number" { send "\r" }
expect "Work Phone" { send "\r" }
expect "Home Phone" { send "\r" }
expect "Other" { send "\r" }
expect "correct?" { send "y\r" }

如果在之后键入了较少的/etc/passwd，则应该在列表中看到您的testuser。

• 添加-d开关可以使expect的行为更加可预测，而且它对调试非常有用
• expect-s可以是精确的，也可以是松散的(例如，精确匹配vs 'contains')
• 某些操作可能需要根..。类似加载项

使用Expect版本5.45对Ubuntu16.04进行了测试。

Answer 2

看起来所有这些都是错误的：expect " Something []: "

我会用expect -ex {Something []: }

1. 它使用“精确”匹配，因为您不需要glob或regex模式的强大功能，而且
2. 大括号确保括号不被解释为Tcl命令替换语法。

Answer 3

expect "Is the information correct? \[Y/n\]是你的问题。

删除Y/n

expect "Is the information correct? send "y\r"

您在代码中丢失了y或n，如果不删除Y/N，也会出现错误。

我这样做(用我的覆盆子)：

#!usr/bin/expect

spawn sudo adduser [lindex argv 0]

set password [lindex argv 1]

#depends what os ur are using

expect "xy something about new passwort:"

send "$password\r"

#depends what os ur are using

expect "blabla type it again blabla:"

send "$password\r"

expect "        Full Name []: "

send " \r"

expect "        Room Number []: "

send " \r"

expect "        Work Phone []: "

send " \r"

expect "        Home Phone []: "

send " \r"

expect "        Other []: "

send " \r"

expect "Is the information correct?"

send "y\r"

这样，您就不需要将密码写入脚本中。

chmod +x 'yourscriptname'

execute 'yourscriptname' 'newusername' 'pwfornewuser'
