I've seen many similar questions, but none really works for me.
I have a simple script that downloads latest 2 video episodes from one channel, so I can watch them later on mobile in offline mode. It uses yt-dlp command with -w switch not to overwrite if video exists. I would like to colorize "Destination" so I see more clearly file name, and "has already been downloaded" if file has already been downloaded.
So my script looks like this:

    cd /tmp
EPI=$(curl -s https://rumble.com/c/robbraxman | grep  -m 2 "href=/\v"| awk '{print $5}' |awk -F\> '{print $1}')
for i in ${EPI//href=/http://rumble.com}; do
  printf "\e[1;38;5;212m Downloading \e[1;38;5;196m $i\e[m \n"
  yt-dlp -f mp4-480p -w $i
done

output of the yt-dlp is like:

So I would probably need to pipe output somehow, and then color it. yt-dlp actually colors progress when downloading. I've tried to put grc in front of yt-dlp but didn't color it.

  • I don't work with `yt-dlp` so I'm not sure if/how `yt-dlp's` colorization may interact with your desired colorization so fwiw .... [this answer](https://stackoverflow.com/a/74987715) may be of interest if the objective is to apply different colors to various strings in the output streaming from the `yt-dlp` call – markp-fuso Feb 04 '23 at 22:28
  • to keep your code less complicated I'd probably wrap the coloeization code (eg, `awk` script from that linked answer) in a function and then have your feed the `yt-dlp` output to the function; ymmv ... – markp-fuso Feb 04 '23 at 22:44
  • Thanks @markp-fuso This use of awk is a bit much for my knowledge, also never really used functions in bash, but probably could learn to use it. Can you propose at least aprox solution. I just want to color filename or message that exists in red. No other colors – DenisZ Feb 04 '23 at 23:20

You can colorize specific things you want using grep:

yt-dlp 'URL' | grep --color -P "^|(Destination.*|.*has already been downloaded)"

Basically it will match all lines with ^, so those lines will still be printed, however since this match contains no visible characters those lines will not be colored.

Then you just add in the parts you want colored after the regex |. The --color shouldn't be neccesary, just adding it to make sure that is not the issue.

  • Thanks @Maximilian ... That works, and very simple/short. It doesn't show % counting while downloading, but good enough. – DenisZ Feb 04 '23 at 23:45
  • @DenisZ You can show percent while downloading in title bar with `yt-dlp --console-title` or you can print as newline with `yt-dlp --newline`. Unforunately `grep` has issues with displaying progress bars natively so there is no perfect way. – Maximilian Ballard Feb 05 '23 at 00:10
  • Thanks @Maximilian, that's brilliant... btw how can I reset console title to `[screen #: user@host:/dir]` – DenisZ Feb 05 '23 at 00:33
  • Maybe the `-E` flag will work as well, no? – Jetchisel Feb 05 '23 at 02:02
  • @Jetchisel Yes `-E` should would work as well. – Maximilian Ballard Feb 05 '23 at 03:29

    btw @MaximilianBallard I was able to reset my console title with help of ChatGPT :) so I added `printf "\033]0;\007"` to my script. (it just removes last part where yt-dlp displays the status – DenisZ Feb 16 '23 at 09:38
