control+R
in bash, it lets you quickly search for previously executed commands.
its very useful and makes things much quicker, i recommend you give it a try.
I use this constantly
i rely on this in my job. if i really need it, i’ll be using it often enough that it’ll always be in ^R distance :)
CTR + u will delete the whole command. I use that a lot so I don’t have to backspace. It’s saved me a ton of time
How about ctrl+c to cancel and clear the command you are typing? It’s much easier because you only need 1 hand, and does not impact your shell’s history.
And then ctrl+y to paste it back and recover that text.
This is great for when you type in your root password incorrectly!
I just use control C, is there a difference other than whether the line shows up or not?
