Command line overwrite
is there a way to overwrite what I have typed in rather than having to hit enter and re enter the command?

What shell are you using?

Do you mean, to bring back a previous command or does your backspace not work?

I'm afraid you need to run a shell that uses the readline library or equivalent, like e.g. bash. You obviously have the unadorned sh running, the grand parent of almost all shells.

I am not sure if I understand the question correctly, but you could use ctrl-u to erase everything you typed in on the line so far and enter the new command rather than pressing the backspace multiple times.

I got to thinking that that was going to be the answer but I am not used to using sh. I'm more tuned to how bash works.

I was wondering if there was a way to clear a wrongly entered character. hitting backspace puts in a different character rather than removing the character.
