Zsh – How to Create a Custom Auto_cd Command

cd-commandzsh

Instead of the normal cd I've created my own function

function cd {
    builtin cd "$@" && ls -F
}

This works great for when I use commands like cd someDir/subDir but not when I change directories via zsh's auto_cd someDir/subDir.

Is there a way to customize what command gets called for auto_cd?

The typical way to run-some-command-on-the-changing-of-the-directory is via the chpwd hook function (or list of functions named in the appropriately named chpwd_functions array):

% function chpwd () { pwd }  
% cd ~/tmp
/Users/jdoe/tmp
% pushd /etc
/etc ~/tmp
/etc
% chpwd_functions=( chpwd_do_ls )
% function chpwd_do_ls () { ls }
% cd /
/

Add arguments from previous command to zsh completion

You can add your completer to the list of completers used by default:

zstyle ':completion:*' completer _last_command_args _complete

How to get the shell functions to make use of existing autocompletion in zsh

To request that a command be completed like another command that is already known to the completion system, you can use the compdef my_command=known_command form of compdef.

compdef s=ssh
compdef {cxterm,uxterm,xterm-color}=xterm

Under the hood, this is basically equivalent to _comps[s]=$_comps[ssh].

Some completion commands apply to a family of functions and read the first word of the command line to determine which particular command to complete. For example, the commands ssh, scp, sftp and a few more are all completed by the function _ssh. In that case, you need to tell the completion function which “service” your function is like (by default, the service is the executable name, here your function's name).

_s () {
  local service=ssh
  _ssh "$@"
}
compdef _s s
