Issue
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?
Solution
The following setting in ~/.zpreztorc caused the annoying warning message to be displayed:
zstyle ':prezto:*:*' color 'yes'
I just commented it out and it's fine now. The warning disappeared.
