Re: [Trisquel-users] Does PlayOnLinux work with Trisquel 8?

Historically, shells have evolved and grown out of earlier shells by adding  
new features or have been developed from scratch because of license  
considerations. You need a way to pass commands and interact with the kernel  
and other programs, so the shell is out there to take care of that. Modern  
graphical user interfaces have mostly hidden the shell from the user. Some  
systems are headless, so you use the shell from another computer like a  
laptop connected to a serial interface or remotely.
