I'm trying out zsh and there's a tab-completion behavior that I'm finding annoying: It seems that if I type cd str and hit TAB, it will auto complete with *str*. For example, cd pl TAB results in an autocompletion of cd Applications/ because 'Applications' contains 'pl'.

Is there a way to turn this off?

I know zsh has a tab completion feature where cd /u/loc/b TAB will get you to /usr/local/bin. Is this behavior related?

  • Operating System: OSX 10.11
  • Zsh version: 5.0.8
  • oh-my-zsh plugins: git, zsh-syntax-highlighting, z


I've tracked the offending block of code down to my ~/.oh-my-zsh/oh-my-zsh.sh file.

67 if [[ $ZSH_DISABLE_COMPFIX != true ]]; then
68   # If completion insecurities exist, warn the user without enabling completions.
69   if ! compaudit &>/dev/null; then
70     # This function resides in the "lib/compfix.zsh" script sourced above.
71     handle_completion_insecurities
72   # Else, enable and cache completions to the desired file.
73   else
74     compinit -d "${ZSH_COMPDUMP}"
75   fi
76 else
77     compinit -i -d "${ZSH_COMPDUMP}"
78 fi

I'm still reading documentation and trying to figure out exactly what's going on.


Ok. I think I've got it sorted out. This post was very helpful.

Basically, oh-my-zsh sets the completion to

zstyle ':completion:*' matcher-list 'm:{a-zA-Z}={A-Za-z}' 'r:|[._-]=* r:|=*' 'l:|=* r:|=*'

Removing 'l:|=* r:|=*' (which is the last rule) now gives me the desired behavior.

The ability to do cd /u/lo/b/ TAB is not compromised.
