If you share a computer or have small children you don’t want visiting certain sites, here is a way to easily block them if you are an Ubuntu user:

1) you will need to have sudo permission

2) run the following command to edit /etc/hosts – sudo gedit /etc/hosts

3) Now, under the lines:

127.0.0.1       osgood-desk     localhost.localdomain   localhost
127.0.1.1       ubuntu.ubuntu-domain    ubuntu

127.0.0.1       osgood-desk     localhost.localdomain

The next step is to simply add:

127.0.0.1 examplesite1.com

127.0.0.1 examplesite.com

4) Now, anytime someone tries to visit examplesite1 or examplesite2, their browser will be unable to access the site.

Setting Bash Environment Variables

If you are using the shell in Ubuntu and want to change your $PATH or $HOME variable permanently and not on a per session basis, the easiest way, IMO, is to simply edit ~/.bashrc. Adding the following line to .bashrc will add some directories to your $PATH variable:

‘export PATH=$PATH:/path/to/some/dirs:/path/to/some/more/dirs’
