readling, ctrl-u is not working like linux console

Hi,

I find it the barebox console's ctrl-u is not working like my linux host.
for now, the barebox's ctrl-u discard the whole line. but the linux consle just remove characters before cursor. is the barebox ctrl-u follows any standard, if not, how about make it just works like linux(ah, it is gnu readline) does.

FWIW, in bash on both my tty2 and urxvt, Ctrl-U clears the whole line. But I don't know if there is a standard for this shortkey.

did you try to move your cursor in the middle of a line.

I guess my bash use this keybinds:

[1] https://www.gnu.org/software/bash/manual/bash.html#Bindable-Readline-Commands

8.4.4 Killing And Yanking
kill-line (C-k)
Kill the text from point to the end of the line.

backward-kill-line (C-x Rubout)
Kill backward from the cursor to the beginning of the current line.

unix-line-discard (C-u)
Kill backward from the cursor to the beginning of the current line.

kill-whole-line ()
Kill all characters on the current line, no matter where point is. By default, this is unbound.

In some shells, like mksh, the default behaviour of ctrl-u is to kill the whole line. But then it's not called unix-line-discard, and I don't think mksh uses readline, either. The "standard" is probably just readline, though it makes me wonder where the "unix" came from…

The program in a Unix-like system that allocates machine resources and talks to the hardware is called the “kernel”. GNU is typically used with a kernel called Linux. This combination is the GNU/Linux operating system. GNU/Linux is used by millions, though many call it “Linux” by mistake.
