I have about a hundred fonts that I need to install. Manually right clicking every font file and clicking install, then selecting "personal" vs "system" in a dialog that appears, and then closing it is tedious. Is there a command that will let me achieve the same effect in one shot? (I am using KDE.)
Sure, just move all of the fonts you want to install to
Note you might have to restart the application you want to use the fonts in for the changes to take effect.
