Honestly, restarting the shell would be a whole lot easier and faster.
Just "exec bash" should be enough to undo one-off "bind" commands, as
long as you didn't mess up the .inputrc or .bashrc files, or poke around
the terminal with stty.  (Following up with "reset" wouldn't be a bad
call, though, just in case.)


Didn't think about "exec bash", thanks. However, it's essentially a restarting. So you loose the environment, e.g.

If by "environment" you mean the exported environment variables.. `exec' "retains" them, they will be accessible:

export EXPORTED=foo; non_exported=bar; exec bash -c 'echo "$EXPORTED $non_exported"'

-> foo

(perhaps run the above after having run an additional copy of bash if your terminal program, say gnome-terminal, closes the window when the shell exits, as the exec'd bash will exit immediately after echo'ing).

Or, what you mean by "environment"?
