title: zsh gsed command not found
body: <p>I am using oh my zsh. I am not able to use some commands which I could do on ubuntu for e.g.. \s in regular expressions. I installed home-brew and then <code>brew install gnu-sed --default-names</code> but still I am unable to used sed command. my $PATH variable is a bit messed up and I am not sure how to correct it. <code>/Users/ishansrivastava/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin:/opt/local/sbin:/opt/X11/bin:/Library/TeX/texbin</code>. <strong>What should I do so that I can use all gnu commands without hassle on my Mac?</strong> also please give me the list of commands on which I have to use gnu command instead of default for e.g..gsed instead of sed etc </p>
