Linux is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. Most Linux distributions , as collections of software based around the Linux kernel and often around a package management system , provide complete LAMP setups through their packages.
In computing, Bash (short for "Bourne Again SHell,") [7] [8] [9] is an interactive command interpreter and command programming language [10] developed for UNIX-like operating systems. Created in 1989 [ 11 ] by Brian Fox for the GNU Project , [ 12 ] it is supported by the Free Software Foundation [ 13 ] and designed as a 100% [ 14 ] free ...
Most programming languages support Linux either directly or through third-party community based ports. [125] The original development tools used for building both Linux applications and operating system programs are found within the GNU toolchain, which includes the GNU Compiler Collection (GCC) and the GNU Build System.
A scripting language or script language is a programming language that is used for scripting. [ 1 ] Originally, scripting was limited to automating an operating system shell and languages were relatively simple.
Some popular cross-platform scripting languages are: bash – A Unix shell commonly run on Linux and other modern Unix-like systems, as well as on Windows via the Cygwin POSIX compatibility layer, Git for Windows, or the Windows Subsystem for Linux. Perl – First released in 1987. Used for CGI programming, small system administration tasks ...
The S-Lang programming library was started in 1992 by John E. Davis, considering that functions he wrote for a text editor might be useful in other programs. [5] The earliest version of the library contained input/output routines for interacting with computer terminals and an implementation of a simple stack-based interpreter with a PostScript-like syntax that he developed for use in a ...
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts. [2]
Declarative programming stands in contrast to imperative programming via imperative programming languages, where control flow is specified by serial orders (imperatives). (Pure) functional and logic-based programming languages are also declarative, and constitute the major subcategories of the declarative category. This section lists additional ...
