Re: Dynamic colored command in zsh

[Roy Zuo <roylzuo@xxxxxxxxx>]

Hi Julien,

Which version of zsh are you using? If you are using 4.2.x, i.e. the default
version under Centos 5, you would have this problem because operator "=~" is not
defined. Even if you are able to get around this, you still cannot use my script
because "region_highlight" is not defined in 4.2.x too.
