If I wanted to see just orange-box, then I would do
grep --color=always orange-box file.txt
But, I don't want to see just orange-box. I want to see orange-box and compare against other cases of box. So I would do:
grep --color=always box file.txt | grep --color=always orange-box
Without that --color=always, other cases of box will be drowned out by the noise.
And if I wanted to write that out to a file then I would do
grep --color=never orange-box file.txt > matches.txt
Alternatively, I'd add a filter to the file with `ansi2txt`
grep --color=always box file.txt | grep --color=always box | ansi2txt > no-color-matches.txt
- rixed 6y agoI think the point the person you are replying to was trying to make is that in your proposed sequence of colored greps, the second one would not catch the "orange-box"es because of the extra chars added for coloring the output of the first grep. Maybe grep should ignore ansi sequences optionally or by default, to solve this?
