Have been using grep to colour the filename printed by tail using grep, by setting GREP_COLOR. However the setting does not work with GREP_COLORS.
Additionally, I could not set colour values with tput commands. tail -v -n "$tm" $file | GREP_COLOR='01;32' $_GREP -e ^ -e '^==> .* <==$' awk and sed work better with colour settings, including settings with tput. Cholden
