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

问题描述

根据 Unix屏幕命令的文档

这里是我的cofig：

$ b，你可以在.screenrc中配置它，并运行一个你指定的命令。
$ b

 ＃默认屏幕
屏幕-tshell_01 
屏幕-tautotest2 cd〜/ project / contactdb; autotest 
  

它不会运行autotest命令。当我开始屏幕时，我试图运行 autotest 的窗口会立即关闭。

我也试过了...

  screen -tautotest2 cd 〜/ project / contactdb 
  

结果相同。

我也试过...

  screen -tautotest2 ls 
  
 
 
 
同样的结果。
 
 
 
让它运行命令的秘诀是什么启动时给定的屏幕？
解决方案
程序正在运行（除了cd外），它只是在运行没有父shell，因此一旦完成，就会退出并完成。
 
 
 
您可以：
  screen -tautotest2 bash -c'cd〜/ project / contactdb; autotest'
  
产生两个弹壳，但生命可能会继续。
 
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.

Here's my cofig:
# Default screens
screen -t "shell_0"  1
screen -t "autotest" 2 cd ~/project/contactdb ; autotest
It will not run the autotest command. That window where I'm trying to run autotest just closes instantly when I start screen.

I also tried it with just...
screen -t "autotest" 2 cd ~/project/contactdb
Same result.

I also tried...
screen -t "autotest" 2 ls
Same result there too.

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

You could do:
screen -t "autotest" 2 bash -c 'cd ~/project/contactdb ; autotest'
Spawns two shells, but life will probably go on.
