Command Completion and up-arrow

Command Completion and up-arrow

[Corwin Zechar]

Hi -

In tcsh, when I put the following lines in my .tcshrc:

        bindkey -k up history-search-backward
        bindkey -k down history-search-forward

The effect is that when I type one or more characters and press 
up-arrow, tcsh attempts to match commands in my command history to the 
characters I have typed.

Is there a way to do this in zsh?

Do I need to write a completion function?

Thanks


Corwin

yes

no

Just use the same commands as you used in tcsh, but drop the -k and
you have to write the literal code for "up" and "down", ie something
like ^[[A and ^[[B.

You might also try

	bindkey "^N" history-beginning-search-forward
	bindkey "^P" history-beginning-search-backward

This searches on the complete string to the left of the cursor and not
just the first work on the command line.
