Currently, I have the following in my .zshrc:

bindkey '^[[A' up-line-or-search
bindkey '^[[B' down-line-or-search

However, this only seems to match the content of my current input before a space character occurs. For example, sudo ls / will match every line in my history that begins with sudo, while I would like it to only match lines that match my entire input. (i.e. sudo ls /etc would match, but not sudo cat /var/log/messages)

What do I need to change in order to gain the desired behavior?

Here is my entire .zshrc in case it is relevant:

This is the documented behavior:

Move down a line in the buffer, or if already at the bottom line, search forward in the history for a line beginning with the first word in the buffer.

There doesn't seem to be an existing widget that does exactly what you want, so you'll have to make your own. Here's how to define a widget that behaves like up-line-or-search, but using the beginning of the line (up to the cursor) rather than the first word as search string. Not really tested, especially not on multi-line input.

up-line-or-search-prefix () {
  local CURSOR_before_search=$CURSOR
  zle up-line-or-search "$LBUFFER"
zle -N up-line-or-search-prefix

An alternate approach is to use history-beginning-search-backward, but only call it if the cursor is on the first line. Untested.

up-line-or-history-beginning-search () {
  if [[ -n $PREBUFFER ]]; then
    zle up-line-or-history
    zle history-beginning-search-backward
zle -N up-line-or-history-beginning-search

Thanks, Gilles, your first solution works pretty well, but there's one issue and I'm hoping you can help me resolve it. When I call up-line-or-search-prefix on an empty input, it gives me the last run command -- the desired behavior. However, when I run up-line-or-search-prefix again, it does an up-line-or-search on the first character of my input. Is it possible to somehow change things so that pressing the up arrow with an empty input will scroll through my history? –  rps Jul 14 '11 at 16:33
@rps Ah, gotcha, it was picking up the first word because the argument was missing (instead of being empty as it should have). Use my edited version. –  Gilles Jul 14 '11 at 23:02

zsh provide this functionality by using



bindkey "^[[A" history-beginning-search-backward
bindkey "^[[B" history-beginning-search-forward

Have also a look at the zsh-history-substring-search project.

It offers what you are looking for, and it can even be used as a oh-my-zsh plugin.
