Expect 不在屏幕上执行脚本

Question

我试图在 screen 到 expect 和 ssh 中执行脚本，但它从未执行过。我知道这一点是因为我没有看到 screen 与 screen -list 的会话。 Expects的退出代码是0，如果我手动通过SSH执行命令，就可以了。

我做错了什么？（也欢迎其他实现我目标的方法）。

剧本：

#! /bin/bash
expect -d <<-EOF
    set timeout -1
    spawn ssh ${user}@${host}
    expect {
        "yes/no" { send "yes\r"; exp_continue }
        "password: " { send "${pass}\r" }
    }
    expect "*# "
    send "screen -dm bash -c './${CLIENT_SCRIPT_LOG}'\r"
    exit 0
EOF
exit $?

调试输出：

[.. cut ..]
expect: set expect_out(buffer) "\r\nLinux client 4.9.76-Rxx-rt61-gb7ccafd-dirty #1 SMP PREEMPT RT Wed Apr 1 13:14:00 CEST 2020 armv7l\r\n\r\nThe programs included with the Debian GLinux system are free software;\r\nthe exact distribution terms for each program are described in the\r\nindividual files in /usr/share/doc/*/copyright.\r\n\r\nDebian GNU/Linux cs with ABSOLUTELY NO WARRANTY, to the extent\r\npermitted by applicable law.\r\nLast login: Thu Jan  1 05:29:03 1970 from 192.168.138.2\r\r\nroot@client:~# "

好吧，看来要等命令执行完退出终端了。否则我认为 expect 太快了。

send "screen -dm bash -c './${CLIENT_SCRIPT_LOG}'\r"
expect "*# " { send "exit\r" }
exit 0

Expect 不在屏幕上执行脚本

Expect doesn't execute script in screen

ssh

bash

gnu-screen

expect
