Learning to use the command line will open up endless possibilities for you - it is undoubtedly essential in web development and programming, but even regular users doing everyday tasks will benefit. When I inevitably encountered a situation where I had to gain some basic command line knowledge, I discovered how useful and easy it is. I thought it was something only really advanced users knew anything about. I didn't know anything about it, and it seemed scary and overwhelming. You might be like me - I used computers for twenty years without ever touching a command prompt.
