On bash command-line, how to delete all letters before cursor?
In zsh, Alt+w clears all characters before the cursor.
In contrast to bash this does NOT cut them; it just deletes them.
This applies to zsh's Emacs mode (which is the default), NOT to Vi mode.
Ctrl-u - Cut everything before the cursor
Other Bash shortcuts,
- Ctrl-a
