linux - Expect脚本完成后不退出

Question

我有以下情况。

我的主要期望脚本看起来像这样

#!/usr/bin/expect -d
set timeout 900
spawn main_ksh_script.ksh [lindex $argv 0]
expect {
        "Press ENTER to Continue" {
            send_user "Message1\n"
            send "\r"
            exp_continue}
        "Press any key to continue" {
            send "\r"
            exp_continue}
         eof {
            send "\003\177\015"
            send_user "EOF reached\n"
            exit 0}
         timeout {
            send_user "Job timed out\n"
            send "\003\177\015"
            exit 100}
}
interact {
\015 {send "\015"}
\003 {send "\003\177\015"}
"\033\[3~" {send "\177"}
}

我的主要 korn shell 脚本 (main_ksh_script.ksh) 是一个非常大的脚本，可以为所需的环境做很多事情。其中之一就是运行守护进程和一些远程作业。这是一个非常简短的例子...

while true; do
    clear
    echo "\n\tDo You Want to deploy xxx!!!  ([Yes]/No) \c"
    read yn1 ;
    case ${yn1} in
    [Yy]*|$enter)
        clear
        echo "SomeJobName1" on Environment (${envNum})\n"
        secondScript.expect environment$envNum@host "Some command(s)"
        echo "End of SomeJobName1" on Environment (${envNum})\n"

        echo "SomeJobName2" on Environment (${envNum})\n"
        secondScript.expect environment$envNum@host "Some command(s)"
        echo "End of SomeJobName2" on Environment (${envNum})\n"

        #And so on...
        break ;;
    [Nn]*) break ;;
    *) echo "\n\tPlease choose Yes or No\c"; pau ;;
    esac
    pau
done

secondScript.expect 看起来像这样......

#!/usr/bin/expect -d
set timeout 300
spawn ssh -o PubkeyAuthentication=no [lindex $argv 0] -n [lindex $argv 1]
expect {
        "Operational Job ended successfully" {
                send "\003\177\015"
                exp_continue}
        "Operational Job ended with failure" {
                send "\003\177\015"
                exp_continue}
        "Press ENTER to Continue" {
                send "\r"
                exp_continue}
        "Press any key to continue" {
                send "\r"
                exp_continue}
        "Password:" {
                send "mypassword\r"
                exp_continue}
        eof {
                send "\003\177\015"
                send_user "EOF reached\n"
                exit 0}
        timeout {
                send "\003\177\015"
                exit 100}
}
interact

问题是，当 main_ksh_script.ksh 完成时，第一个 expect 脚本(通过生成进程调用它的脚本)不会退出。我必须打开新终端，然后用“kill -9”将其杀死。甚至无法发送 Ctrl+c。

编辑...如果我从两个 expect 脚本中删除“交互”，我将不会得到任何结果。这就是主脚本尾部的样子。

expect: does " \c\r\n\r\n" (spawn_id exp6) match glob pattern "Press ENTER to Continue"? no
"Press any key to continue"? no
expect: read eof
expect: set expect_out(spawn_id) "exp6"
expect: set expect_out(buffer) " \c\r\n\r\n"

它仍然不会自行终止，我仍然无法通过任何其他方式杀死它，期望通过另一个终端的 kill 命令。

如果你想让第一个expect脚本结束，interact命令在最后做什么？您需要使用 interact 命令来检测 eof。

interact {
  ...
  -o
  eof {puts "spawned process completed"; exit}
}

-o 表示将从派生进程而不是用户检测以下规则(“eof”)。
