The auto-correct feature of zsh is sometimes helpful, but most time will annoy me.
Such as:
$ tankywoo::octopress/ (source*) » ls
_deploy Gemfile plugins public ...
$ tankywoo::octopress/ (source*) » rake deploy
zsh: correct 'deploy' to '_deploy' [nyae]?
To disable this feature, there are some ways.
Disable autocorrect on specific command
alias rake='nocorrect rake'
nocorrect is a precommand modifier that prevents a spell check on any following words.
Disable autocorrect entirely
For newer versions of zsh:
unsetopt correct
For older version of zsh:
unsetopt correct-all
Use oh-my-zsh
The newer version of oh-my-zsh can control this feature:
# Uncomment following line if you want to disable autosetting terminal title.
# DISABLE_AUTO_TITLE="true"
default is enable, uncomment it and disable autocorrect feature.
