I think it is better to descript it what it ctrl-u does: Kill backward from the cursor to the beginning of the current line. :) Regards, duhuanpeng ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox

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.
