This is very different from PC operating systems such as MS-DOS or MS-Windows (which allows multiple tasks to be carried out simultaneously but not multiple users). UNIX is a machine independent operating system. Unix is primarily a command line based operating system with additional applications, such as X Window System, to give a graphic oriented operating system similar to Windows. Since Unix is often used from the command line, there are various shells. A shell is a large add-on or modification of the Unix operating system.

Unix is a portable, multitasking, multiuser, time-sharing operating system (OS) originally developed in 1969 by a group of employees at AT&T. Unix was first programmed in assembly language but was reprogrammed in C in 1973. Unix has been ported to more machine families than any other operating system.

On Linux and macOS, the date program is the core utility for dealing with date/time, including Unix timestamps. Called without any arguments, it returns the current date/time in a human-readable format: The unix time stamp is a way to track time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970 at UTC. Therefore, the unix time stamp is merely the number of seconds between a particular date and the Unix Epoch.

A Unix domain socket or IPC socket (inter-process communication socket) is a data communications endpoint for exchanging data between processes executing on the same host operating system. Valid socket types in the UNIX domain are: SOCK_STREAM (compare to TCP) – for a stream-oriented socket Unix time (also known as Epoch time, POSIX time, seconds since the Epoch, or UNIX Epoch time) is a system for describing a point in time.It is the number of seconds that have elapsed since the Unix epoch, minus leap seconds; the Unix epoch is 00:00:00 UTC on 1 January 1970 (an arbitrary date); leap seconds are ignored, with a leap second having the same Unix time as the second before it, and Se hela listan på opensource.com UNIX served as the inspiration for free open-source operating systems such as Linux and FreeBSD, and it is the basis for Apple Inc. ’s Mac OS X.
