I have a bash function that changes the directory of my current bash session. I'd like to call the function by pressing Alt-M and am using bind -x to create this mapping. After entering Alt-M on my keyboard, nothing happens in my bash prompt - there is no new line as there would be if a function were typed and then Enter was pressed. I have to press Enter again to get a new prompt on a new line.
How can I force there to be a new prompt on a new line? If I call the function directly/normally (i.e. by typing foo and then hitting enter), the command will work as expected and there will be a bash prompt on a new line, with a refreshed PS1.
Using echo or printf commands in the function doesn't work - it prints a new line, but above the bash prompt, and the bash prompt doesn't refresh. What exactly is not happening here that I want to happen?
foo(){
dir="/some/path"
cd $dir
}
bind -x '"\em": foo'
If you use a macro instead of a shell function, you can inject a return keypress:
bind '"\em": "\C-ex\C-u foo\C-m\C-y\C-b\C-d"'
\C-e moves to end of linex appends something to ensure line is not empty\C-u deletes the line and saves it in the kill ring foo is the command - leading space stops it getting added to history (assuming HISTCONTROL=ignorespace)\C-m injects the return keypress\C-y restores the original line\C-b\C-d removes the extraneous x we addedI don't know how to move the cursor back to its original position if it wasn't at end of line. Also the kill ring gets polluted.
