问题描述
我为FFmpeg运行多个bash脚本.但是,由于打开了多个窗口,因此我无法跟踪运行的文件,因为我直接从脚本执行文件,因此没有运行历史的记录.唯一的历史记录是我调用的第一个文件
I run multiple bash script for FFmpeg. However, since I have several windows open, I lose track of what file I ran since I execute the file directly from the script there is no history of what I ran. The only history there is the first file I called
例如:
enter tv number i.e 19: 19
stream key: key
Press [enter] to execute tv19
我按Enter键,它运行tv19,但是在该窗口中没有运行tv19的记录,因此如何将命令回显到$
I press enter, and it runs tv19 but there is no record I ran tv19 in that window, so how can I echo the command to the $
像这样
[ibrod ~]$ ./tv19
然后我可以按Enter键并使用向上箭头,直到我知道我在那个腻子窗口中运行了什么文件.
than I can press enter and use the up arrow than I know what file I ran in that putty window.
推荐答案
感谢您的帮助,我想出了另一种方法.我将提示更改为[tv10〜] $
Thanks for the help, I figured another way. I change the prompt like [tv10 ~]$
只是更改了文件,放入了我的
just made a file changetv i put inside
PS1="[$1 \W]\$ "
所以我运行文件并将其命名为
so I run the file and call it as
. ./changetv tv10
所以现在我知道什么窗口是什么. :)
so now I know what window is what. :)
