Thanks for the PR, it looks very good!

Well, Im only on my phone right now and can not really examine.
But two things come to my mind:

Iirc we have MIT license for all scripts, that simple "rule" would break with the license you choose.

Second I do not get the dependency on fc-cache. I didnt encounter a system that needs a fc-cache call for years.

And third ;-) apple has this bash 3 only, i would tweak the script to avoid the newer features.

But, whatever, great work!

Iirc we have MIT license for all scripts,

Sorry for my ignorance about .. changed lic to MIT --> diff

Second I do not get the dependency on fc-cache.

fc-cache itself might not be needed, but the existence of this command ensures that a fontconfig freedesktop.org infrastructure (desktop vs. server distros) is installed .. if you insist, I can remove the use of fc-config.

apple has this bash 3 only

This script is written for Linux distros with a fontconfig freedesktop.org installation.

I sorted out my last Mac OS systems many years ago, but I suspect:

• Apple shipped the 2007 version of Bash v3 and cannot upgrade to Bash 4 due to GPL3 restrictions.
• Same with fontconfig / compared to what I know from Linux, Apple might have it own quirks (IDK but I would expect some differences)

Homebrew is the (missing/unofficially) package manager for Mac-OS and has a package for a updated version of bash .. however, Mac users are recommended to install the fonts from https://formulae.brew.sh/cask-font

To clarify: Installation scripts like the one in this PR do not replace a package manager; for example, this script does not offer automated updates (only manually or via a crontab entry).

Nerd Fonts should be installed (if possible) via the distribution's package manager. On voidlinux, for example, I use the nerd-font package. For macOS, Homebrew is (probably) recommended. TBH: I have no idea if there exists something similar for Windows .. Scoop? .. and Scoop bucket for Nerd Fonts?

Last two force push fixed issues when TERM is unset and/or the script is used in a pipe (e.g. VERBOSE=2 ./fc_install list | grep Nerd).

Sorry for the force push mess / I hope I have now fixed last issues and PR is ready for review.

Well, Im only on my phone right now and can not really examine.

ping @Finii .. if you have time, can you review / thanks ..
