linux:remove-foreign-fonts-from-debian-ubuntu

Remove foreign fonts from Debian, Ubuntu and derivatives

To get rid of tons of asian, arabic, oriental fonts takes ages by hand. This script I've made for my Debian 10, removes:

  • All non english fonts
  • All the Libreoffice help files except those indicated in the variable KEEP
  • All the Libreoffice locales except those indicated in the variable KEEP
  • All the Firefox locales except those indicated in the variable KEEP

This process frees 1.4 GB and a lot of inodes, but most of all, when you have to choose a font it's a lot easier/faster.

By default the script keeps en-gb + en-us + it. Set the var KEEP to change it.

# Remove oriental/medio-oriental/african/etc. fonts
