What is UNIX? UNIX is a portable, multi-tasking and multi-user computer operating system originally developed by a group at AT&T Bell Labs. What are the benefits and advantages of using UNIX? - UNIX can communicate with many different types of computers, it is not limited to a specific brand, type, or operating system. - Most UNIX operating systems come with a free email program called Sendmail. - UNIX provides tight administrative control, it has a mechanism for limiting a users disk usage in addition to passwords and file permissions. - UNIX allows shared network filesystems to be mounted at any point in a directory structure. A network share can also span multiple disk drives (or even different machines) in UNIX, thus allowing administrators to maintain pre-existing directory structures that are well-known to users, yet allowing them to expand the available disk space on the server, making such system changes transparent to users. - UNIX was conceived as a client/server operating system for professional use. - UNIX operating systems are equipped with scripting languages such as Bourne Shell, Korn Shell, C Shell, and sometimes Perl, and a cron facility for scheduling jobs to run at fixed intervals (every n minutes, every n hours, once a week, once a month, etc.). Cron scheduling is highly configurable.
