(grep "grep -r -nH -e TODO ~/git/emacs-pdf") Is there a deeper reason that --color is required to see the number of matches? Could it simply count the number of matched lines if no --color was specified? Or is it not easy to detect? I would like to see the number of matches with alternative programs like ripgrep: (grep "rg -nH --no-heading --color=always -e TODO ~/git/emacs-pdf") (grep "rg -nH --no-heading --color=ansi -e TODO ~/git/emacs-pdf") But the --color argument here does not seem to have an effect. Thanks in advance, Tomas
