Ctrl-P 在 mac 终端上的命令行编辑 vi 模式下不起作用

Question

https://www.gnu.org/software/bash/manual/html_node/Readline-vi-Mode.html said we could do set -o vi to use vi mode instead of emacs mode for command line editing.

And the help: ex-edit-index sais

c_CTRL-P        CTRL-P          after using 'wildchar' with multiple matches:
                                go to previous match, otherwise: recall older
                                command-line from history.

However when I press CTRL-P I just got ^P

May I know why ?

Answer 1

Readline's "vi mode" is neither vi nor Vim. It is a partial emulation of vi shoehorned into the command line context.

That <Cp> you are referring to is a Vim command so there is no reason whatsoever to expect it to do anything in that context. Vim's documentation is totally irrelevant in this case.

Search for Vim Mode bindings in $ man readline for the actual bindings at your disposal in that "mode".
