如何执行对话命令，并让它回到原来的屏幕? [英] How to to execute a dialog command, and have it return to the original screen?

问题描述

新手，不知道怎么问.

shell命令执行的技巧是什么，执行完会回到原来的屏幕?

What is the trick to execute a shell command, upon finishing, it will return to the original screen?

我正在使用 dialog 编写一个 shell 脚本，说它会打开一个基于控制台的 UI，然后当我退出它时，它看起来像:

I am wring a shell script using dialog, say it will open a console based UI, then when I exit it, it will looks like:

$ ./run_a_script_containing_dialog.sh
++++++++++++++++++++++++++++++++++++++
+.......
++++++++++++++++++++++++++++++++++++++
++++++++++++++++++++++++++++++++++++++
++++++ A BLUE BACKGROUND DIALOG ++++++
++++++++++++++++++++++++++++++++++++++
++++++++++++++++++++++++++++++++++++++
+.......
++++++++++++++++++++++++++++++++++++++
$ (Upon finishing, prompt would be here)

我真正想要的是:

$ ./run_a_script_containing_dialog.sh
$ (Dialog is still opened as normal, but upon finishing, prompt would be here)

我希望看到一种行为，就像我们通常在使用 man 时看到的那样，当您按 q 时，它会返回到您的原始屏幕.

I'd like to see a kind of behavior just like what we typically see in using man, when you press q, it will return to your original screen.

PS:如果您认为这个解决方案与上面的完全不同，请原谅我.

如何写一个shell脚本来实现这个效果?假设这个脚本只是简单地列出当前文件夹中的文件，但它会在新屏幕中列出它们.

How to write a shell script to achieve this effect? Let's say this script will just simply list the files in the current folder, but it will list them in a new screen.

$ ./a_personal_ls.sh (a new screen will open and list the files in $PWD)
$ (Pressing `q` will cause the new screen disappear, and prompt will be here)

这在 shell 脚本中可行吗?

Is this doable in shell scripting?

推荐答案

尝试将名称有点混乱的 --keep-tite 选项传递给 dialog(作为第一个选项).

Try passing the somewhat confusingly named --keep-tite option to dialog (as the first option).
