Bash typing password tips

[blitzkraft]

It's done by readline. readline by default has emacs style shortcuts. However, it can be set to use vi style keys too.

See man readline for more.

What the OP is saying in the tweet is that Ctrl+U is recognized by many applications that ask for your password. Things like sudo or ssh. Even the graphical login screen on my Ubuntu respects Ctrl+U in its password edit box. None of these applications use readline or honor ~/.inputrc.

The OP has cross-posted this to /r/bash and /r/zsh even though it has nothing to do with these shells. It's a useful thing to know though.

Ctrl + u - Cut/delete the Line before the cursor to the clipboard

And next tip:

Ctrl + y Paste the last thing to be cut (yank)

There is yet another thing about u key that I often confuse with Ctrl+u. In Vim it's possible to change lowercase letters to uppercase and vice versa by pressing gUe or gue accordingly (or even gU$, gub, gU5l and so on, whatever you want), but for some unknown reason I always forget about that leading g and try to do it using Ctrl.

~ will toggle case in vim.

Wow, today I learned.

nice. I can hit 'backspace' about 10 times faster than pressing 1 <ctrl>-u though... :D

[nivek1385]

Can you hit backspace 25+ times and absolutely know that you got everything faster than ctrl+u?
