期望脚本不识别“--更多--”，之后不会运行任何命令。

Question

我正在编写一个expect脚本来自动安装SO磷。看上去是这样的：

#!/usr/bin/expect

set installdir [lindex $argv 0]
set timeout 20

spawn "./install.sh"

expect {
    sleep 5
    "Press <return> to display Licence. Then press <spc> to scroll forward." {send "\r"}
    -ex "--More--" {send -- " "; exp_continue}
    "Do you accept the licence? Yes(Y)/No(N)\\\[N\\\]" {send "Y"}
    "Where do you want to install Sophos Anti-Virus? \\\[/opt/sophos-av\\\]" {"send $installdir/sophos-av"}
    "Do you want to enable on-access scanning? Yes(Y)/No(N) \\\[Y\\\]" {"send \r"}
    "Do you want to enable remote management? Yes(Y)/No(N) \\\[Y\\\]" {"send \r"}
    "Username for Sophos Anti-Virus GUI? \\\[admin\\\]" {"send \r"}
    "Password for Sophos Anti-Virus GUI?" {"********"}
    "Re-enter the same password." {"********"}
}

interact

当我运行expect脚本时，它输入许可证的击键，但是当第一个“--更多--”提示符出现时，它什么也不做，并且没有运行后续命令。有什么想法？想法？

您是否期望程序依次查看这些模式中的每一个？如果是这样的话，您需要使用多个顺序的expect命令和发送命令：

sleep 5
expect "Press <return> to display Licence. Then press <spc> to scroll forward." 
send "\r"
expect {
    -ex "--More--" {send -- " "; exp_continue}
    "Do you accept the licence? Yes(Y)/No(N)\\\[N\\\]" 
}
send "Y"
expect "Where do you want to install Sophos Anti-Virus? \\\[/opt/sophos-av\\\]" 
send "$installdir/sophos-av\r"
expect "Do you want to enable on-access scanning? Yes(Y)/No(N) \\\[Y\\\]" 
send "\r"
expect "Do you want to enable remote management? Yes(Y)/No(N) \\\[Y\\\]" 
send "\r"
expect "Username for Sophos Anti-Virus GUI? \\\[admin\\\]" 
send "\r"
expect "Password for Sophos Anti-Virus GUI?" 
send "********\r"
expect "Re-enter the same password." 
send "********\r"
interact

一旦expect执行了一个"action“块，expect命令就会返回。除非您告诉它，否则它不会在等待匹配其他模式时出现(exp_continue)

有用的提示:在开发expect脚本时，打开脚本顶部附近的详细调试输出：exp_internal 1。
