#225768 — Re: Bash question hard to formulate

...

  i'm not familiar with that problem but another tip
which is helpful when dealing with a terminal that
gets into a strange state is to press return then
type in reset and press return again.

Typing return when you have already half-a-command line
(and are not sure what it is) is somewhat dangerous.

That's OK, it can be a life style. Be sure to keep some
backups around, then :-)

  haha, yeah...  with github these days my more recent
projects are being backed up "off site" so i'm not too
worried about the most recent changes not being 
available to me in case of a severe crash.  but i do
also keep backups.

  Ctrl-C can also be used to cancel a command in progress.
:)  i'm not often typing dangerous commands into the 
terminal, especially one which is in an odd state.

If characters are typed by a process while you're typing a command
line, then naively trying to backspace over a newline will not work
because bash has a different idea of where the cursor is from reality.

If you just ignore said characters, the command line you typed will
be unaffected, and will execute correctly when you press Return.

That's not going to work. When you "backspace into a sentence", you're
rubbing out characters that *you* typed, even though the characters
that are actually disappearing from the display are the ones that were
displayed last, ie those output by the other process.

If you want the characters that *you* typed to be re-shown, clean, on
the command line, then pressing Ctrl-L is the correct way to do it.
*Then* apply your corrections, using Backspace or the arrow keys as
appropriate.

Cheers,
David.
