1.1. Linux or GNU/Linux, that is the question.
Many people feel that Linux should really be called GNU/Linux.
This is because Linux is only the kernel, not the applications that run
on it. Most of the basic command line utilities were written by the
Free Software Foundation while developing their GNU operating system.
Among those utilities are some of the most basic commands like cp, mv
lsof, and dd.
In a nutshell, what happened was, the FSF started developing GNU
by writing things like compliers, C libraries, and basic command line
utilities before the kernel. Linus Torvalds, started Linux by writing
the Linux kernel first and using applications written for GNU.
I do not feel that this is the proper forum to debate what name
people should use when referring to Linux. I mention it here, because
I feel it is important to understand the relationship between GNU and
Linux, and to also explain why some Linux is sometimes referred to as
GNU/Linux. The document will be simply referring to it as Linux.
GNU's side of the issue is discussed on their website:
