Rebuild Font Cache on Linux
When you add fonts, for instance to your ~/.fonts folder, you’ll need to force
rebuild the font cache.
Help docs
fc-cache --help
Build font information caches in [dirs]
(all directories in font configuration by default).
-f, --force scan directories with apparently valid caches
-v, --verbose display status information while busy
Rebuild
We can force it to re scan the valid caches to find our new fonts.
➜ fc-cache -f -v

Now your fonts will be in your font cache. Allow them to show up properly in the font list of various programs. You may need to restart a program to get it to populate in their font index.
