色付きのコマンドの結果などから html に変換してくれる aha というコマンドを少し試してみました．
Debian では aha パッケージがあるのでパッケージから導入しました．
$ sudo apt install aha
aha の help を変換してみます．
$ aha -h | aha -b | xsel
Ansi Html Adapter Version 0.5.1 aha takes SGR-colored Input and prints W3C conform HTML-Code use: aha <options> [-f file] aha (--help|-h|-?) aha reads the Input from a file or stdin and writes HTML-Code to stdout Options: --black, -b: Black Background and White "standard color" --pink, -p: Pink Background --style X, -y X: Set the style used in the <body> element --stylesheet, -s: Use a stylesheet instead of inline styles --iso X, -i X: Uses ISO 8859-X instead of utf-8. X must be 1..16 --title X, -t X: Gives the html output the title "X" instead of "stdin" or the filename --lang X, -L X: Uses the ISO 639-1 code X for the language --line-fix, -l: Uses a fix for inputs using control sequences to change the cursor position like htop. It's a hot fix, it may not work with any program like htop. Example: echo q | htop | aha -l > htop.htm --word-wrap, -w: Wrap long lines in the html file. This works with CSS3 supporting browsers as well as many older ones. --no-header, -n: Don't include header into generated HTML, useful for inclusion in full HTML files. --no-xml, -x: Don't use doctype xml but html (may useful for old browsers like IE) --css X, -c X: Add css file X to the output. In fact just adds <link rel="stylesheet" href="X" /> to the header. --ignore-cr, -r: Ignore all carriage-returns (ASCII sign 13, \r) which may lead to double new lines in html. Examples: Create an HTML file with a black background, a custom title and a larger font-size using aha's help: $ aha -h | aha -b -t 'aha help' -y 'font-size:1.8em' > aha-help.html Create an HTML file with a white background using the output of diff $ diff -u --color=always oldfile.c newfile.c | aha > diff.html Create an HTML file with a black background from the output of htop. You have to use option -l due the other new-line-commands htop uses: $ echo q | htop | aha -b -l > htop.html Create an HTML file from the output of this man page. man uses bold and underline formatting from nroff, which ul converts to SGR: $ MAN_KEEP_FORMATTING=1 COLUMNS=80 man aha | ul | aha > man-aha.html Copyleft Alexander Matthes aka Ziz 2020 ziz@mailbox.org https://github.com/theZiz/aha This application is subject to the MPL1.1 or LGPLv2+.

lolcat もと思ったら，
$ cowsay hello | lolcat | aha -b -n | xsel
色が付いていません．

パイプのところで消えちゃっています．パイプがあるとパイプの後ろのコマンドが扱えないかもしれないと気を使って色を落としています．
$ echo hello | lolcat | od -xc

-f, --force
Force color even when stdout is not a tty.出ました :)

lolcat は -f オプションで行けましたがそのようなオプションがない場合は unbuffer コマンドなどが使えます． unbuffer コマンドは Debian では expect パッケージに含まれています．
Tip | 以下のようなものもあるようですが未検証． |
$ apt moo moo | aha -b -n

スクリーンショットの方が確実ですが，ちょっとしたことなら html の方がサイズも小さく良いかもしれません．
