[Trisquel-users] Use this bash init script snippet to get an improved prompt. Also can you donate to help us to get a friend out of jail?

Hello fellow free software users!. I want to share with you a small snippet  
that I have in my .bashrc to make a custom prompt, as you can see in the  
attached image. It is licensed under the GNU General Public License version 3  
or any later and you will find it attached to this post. Note that the exit  
status code of the previous command is displayed between the host name and  
the path.

I am also writing to ask for your help to raise funds for the legal defense  
of a friend who is currently in jail. He is known as Alina Davis among  
Russian users for his sometimes feminine and sometimes androgynous appearance  
and sense of fashion You can find information about Alina and how to help in  
this web site. Please help by donating, and also by linking to our  
fund-raising web site from your social media accounts. For those of you who  
use Facebook or Twitter, please help us by linking to Alina's fund raising  
web site from those social networks, especially among those groups that may  
sympathize with Alina's situation. Thanks.
