你如何使用命令启动的Unix命令屏幕？ [英] How do you start Unix screen command with a command?

问题描述

按照文档为Unix的筛选命令，可以配置它.screenrc开始与一帮默认屏幕，每个运行您指定的命令。

According to the docs for the Unix "screen" command, you can configure it in .screenrc to start with a bunch of default screens, each running a command that you specify.

下面是我的cofig：

Here's my cofig:

# Default screens
screen -t "shell_0"  1
screen -t "autotest" 2 cd ~/project/contactdb ; autotest

这将不会运行自动测试命令。在那里我试图运行自动测试这个窗口只是关闭瞬间，当我开始屏幕。

It will not run the autotest command. That window where I'm trying to run autotest just closes instantly when I start screen.

我也刚刚试了一下...

I also tried it with just...

screen -t "autotest" 2 cd ~/project/contactdb

同样的结果。

我也试过...

screen -t "autotest" 2 ls

同样的结果也有。

Same result there too.

有什么秘诀让它在给定的屏幕在启动时运行命令？

What's the secret to getting it to run a command in a given screen on startup?

推荐答案

您的程序正在运行（当然，除了CD），它只是它没有父shell正在运行，所以一旦它完成，它退出就大功告成了。

Your program is being run (well, except the cd), it's just that it's being run without a parent shell, so as soon as it completes, it exits and you're done.

您可以这样做：

screen -t "autotest" 2 bash -c 'cd ~/project/contactdb ; autotest'

产卵两枚炮弹，但生活很可能会继续下去。

Spawns two shells, but life will probably go on.
