From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is there an easy way to filter all terminal commands that contain a --help flag? (lemmy.world)

Or is there maybe a way to set the pager for all help related queries to some command? I'm using bat and would like to pipe all --help through | bat --language=help by default for the syntax highlighting and colored output... Or if you know a lower effort way to color the output of --help let me know.

Frankly, I would be surprised, if anything uses groff for displaying --help, unless it shows the man page for that.
The most basic implementation of --help is a manually formatted multi-line string written into the source code, which gets printed as-is.
For dynamic layouting, you do need more logic, but rendering it to groff source code first does not make that easier. For tabbing, you print an appropriate number of \t.

I agree, I just didn't want to make assumptions about how newer things work with localization these days.
