How to clear the current command line in Linux or Mac terminal?
For example, if you typed a bunch of instructions wrongly, and you want to clear them,
Be sure to do the same as I used to, use the reverse key to kill slowly, we can use ctrl+u
Remove the entire command line directly.
If you press ctrl+u to delete the entire line command,
If you want to restore , you can press ctrl+y .
If you install Vim like me, will there be an error that python2.7 or python3 is required when executing the terminal, but the system obviously has python 2.7? This article explains how I fixed this issue.
I have some audio files downloaded from Youtube that I want to play in the background, do I know how to do it?
If we have changed some files, how to find out through the command line?
