I have an alias which is predefined by an oh-my-zsh plugin. -> % alias gcm gcm='git checkout master' I'd like to remove it, i.e. I'd like alias | pcregrep "\bgcm\b" return 1. I've tried with alias gcm='' but after that the alias is still existent.

You can remove an alias simply using:

$ unalias gcm
  • 1
    will this unalias it forever or only for this session? – meteors Apr 25 '15 at 12:41
  • @meteors Each session starts with no aliases, then they get created via your scripts - so, it depends on what you have in them. – nomadcoder Jul 26 '15 at 10:04

This other answer is correct but if you're adding the unalias gcm line to your .zshrc file, it must be done AFTER oh-my-zsh is sourced, or else it will be overwritten by the zsh defaults.

It would look something like the below in your .zshrc file:

source $ZSH/oh-my-zsh.sh

# must unalias all ZSH defaults here AFTER we source the above
unalias gcm
alias gcm="whatever you want"
