Having been built from the ground up adhering to the JeOS principle, the OS is very lightweight and very suitable for the confined usage range of an HTPC. OpenELEC, a Linux distribution that incorporates the media center software Kodi, is an OS tuned specifically for an HTPC.
In 2001 the market share for the Linux operating system was 25 percent; other Unix flavors 12 percent. 2 server operating system behind Windows NT.
A common feature of Unix-like systems, Linux includes traditional specific-purpose programming languages targeted at scripting, text processing and system configuration and management in general. For example, regular expressions are supported in programs like grep and locate, the traditional Unix MTA Sendmail contains its own Turing complete scripting system, and the advanced text editor GNU Emacs is built around a general purpose Lisp interpreter. Many programs also have an embedded programming language to support configuring or programming themselves. Linux distributions support shell scripts, awk, sed and make.
Unix is an operating system commonly used in internet servers, workstations and PCs by Solaris, Intel, HP etc. Linux is an open source, free to use operating system widely used for computer hardware and software, game development, tablet PCS, mainframes etc.
Linux is an operating system kernel, and UNIX is a certification for operating systems. The UNIX standard evolved from the original Unix system .
The Jet Propulsion Laboratory has used Linux for a number of years “to help with projects relating to the construction of unmanned space flight and deep space exploration”; NASA uses Linux in robotics in the Mars rover, and Ubuntu Linux to “save data from satellites”.
IBM develops an operating system called AIX, which is mostly used on IBM mainframes and PowerPCs. Hewlett-Packard maintains HP-UX, which is used on the HP 9000 line of workstations and server systems. And then there’s Minix, a microkernel operating system that’s now mostly used for educational purposes.
An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.
The Management Packs for UNIX and Linux Operating Systems enable discovering, monitoring, and managing UNIX.

According to the study, if all this software had been developed by conventional proprietary means, it would have cost about . Slightly over half of all lines of code were licensed under the GPL.  Most of the source code (71%) was written in the C programming language, but many other languages were used, including C++, Lisp, assembly language, Perl, Python, Fortran, and various shell scripting languages. 1 found that this distribution contained 30 million source lines of code.  Using the Constructive Cost Model, the study estimated that this distribution required about eight thousand man-years of development time. 4 million lines of code, or 8% of the total. 5 billion (2017 US dollars) to develop in the United States. A 2001 study of Red Hat Linux 7. The Linux kernel itself was 2.
You can specify how many threads to run and the timeout. This tool is exactly what it says, it’s a Multi Threaded TCP Port Scanner with possibility to scan 65535 TCP ports on an IP address. It will tell you the MAC address of the target and the service running – works on both Linux and Windows.
