Introduction
UNIX is basically a multi-user, multitasking operating system. It has around twenty years of history and is very grown-up in terms of performance with a proven track record for performance, consistency, scalability and safety. UNIX grew to its full height after about 30 years of nonstop research and growth with contributions from quite a number of volunteers. The consequence of their dedicated efforts is an operating system which has powerful multiprocessing capabilities and whose performance is still unmatched. It not only meets the demands of today's computing needs, however in a lot of cases exceeds them.
Impact of UNIX System
The UNIX system had a huge impact on the surrounding community. A number of programmers believe it the most powerful operating system in changing other proprietary operating systems, chiefly UNIX to be called the vital operating system may never use.
Subsequent the lead of Multics, its code was written in high level language as opposed to assembler. It had a severely simplified file model compared to numerous current operating systems. The file system hierarchy contained machine services and devices for example printers, terminals, or disk drives, providing a apparently uniform interface, however at the expense of requiring oblique mechanisms for instance ioctl and mode flags to access features of the hardware that did not fit the simple stream of bytes model. (Maurice, 1996)
UNIX is not an only operating system; it refers to a family of operating systems. Various admired members are Linux, HP-UX, SCO, Solaris, SunOS, Digital UNIX, IRIX and AIX. The record continues with a number of other members NetBSD, OpenBSD, BSDI, FreeBSD and Pyramid. UNIX operating systems are set with scripting languages like Bourne Shell, Korn Shell, C Shell, Perl and more. (Maurice, 1996)
