What is the importance of the GNU project?
The GNU project was started by Richard M. Stallman in September 1983 to create an operating system which will be free for users. The users would have freedom to run, share, distribute, study, change and improve or make new changes to the software.
The aim of this project was to build an operating system that is free and also “everything useful that normally comes with a Unix system so that one could get along without any software that is not free." This was called as GNU, a recursive acronym for “GNU's not Unix””. It was based on the design of Unix.
These days the kernel Linux is very common. Outside the kernel,all other parts of the Linux system are GNU. It was taken under version 2 of GNU and hence the name Linux was named to GNU/Linux.
