zsh: no matches found:...

I’ve been on zshell (via oh-my-zsh) for some time and have loved most of it. One of my nits was ‘no matches found’ when running various rake tasks; e.g.

$ rake parallel:spec[4]
> zsh: no matches found: parallel:spec[4]

I was a bit fuddled on the root cause, but today I found the solution and the cause. The root cause was zshell’s substitutions http://zsh.sourceforge.net/Guide/zshguide05.html and the solution was to add

alias rake="noglob rake"

to my ~/.zshrc
