I have zsh + zprezto installed on my Arch linux. Every time I open the console the annoying warning is being displayed: 

grep: warning: GREP_OPTIONS is deprecated; please use an alias or script

Following the instructions in [SOLVED] grep: warning: GREP_OPTIONS is deprecated doesn't help. How can I get rid of this warning?

unset GREP_OPTIONS
