Submitted by abhishek on Fri, 01/30/2009 - 10:43

Need to setup a lab/office with 200+ computers, very tiring job but look if you have machines identical in configuration why are you installing each of them why not install one and replicate it to others this will save a lot of time, But how will i do this?????????? Its very very simple you can do a dd of the source to all destination but this would be even difficult and a bit geeky, hey dont worry we have a solution for it use PXE. 

Now what is this PXE??

How to TTF Fonts in Ubuntu

Simple steps to install TTF fonts on your Ubuntu Machine
  1. Move all your fonts to the ~/ Directory. The ~/ Directory is your home folder. So if you were logged in as abhishek, the directory would be /home/abhishek/ . This step is done only to ease the process you can use any directory for this matter.
  2. Open up the terminal. I'm assuming you've already extracted the font to the ~/ directory.
