Linux: Learn the basics

So, the truth about Linux - I can't tell exactly but the proven fact is Linuxes / Unixes are build for server environments and be the Server rather End client. Servers' need to be very resource efficient and GUIs are never an option when we are critical to our resources.

In short, Linux can be used as Desktop machines but one-way-or-another one needs to use command line to get things done.

While learning to deploy VoIP servers- As I plan on -we must be very friendly with black&white command line screen and learn as we go.

Following are some basic Linux Commands we need every now and then from viewing a directory to creating medium level shell scripts.

cp srcfilename /path/destfilename	Copy srcfilename into directory /path with name destfilename
