GO Programming Language
Go a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language. Go is syntactically similar to C, but with memory safety, garbage collection, structural typing, and CSP-style concurrency. The language is often referred to as Golang because of its domain name, golang.org, but the proper name is Go. Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. Go is portable: it runs on many Unix variants including Linux and macOS, and on Windows.
Python Programming Language
Python is an interpreted, high-level and general-purpose programming language. Python's design philosophy emphasizes code readability with its notable use of significant whitespace. Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes. It supports multiple programming paradigms beyond object-oriented programming, such as procedural and functional programming. Python combines remarkable power with very clear syntax. It has interfaces to many system calls and libraries, as well as to various window systems, and is extensible in C or C++. It is also usable as an extension language for applications that need a programmable interface. Python is portable: it runs on many Unix variants including Linux and macOS, and on Windows.
Perl Programming Language
Perl is high-level, general-purpose, interpreted, dynamic programming language, used for mission critical projects in the public and private sectors. Supports object-oriented, procedural and functional programming. There are over 25k open source modules available from the Comprehensive Perl Archive Network (CPAN). Perl includes powerful tools for processing text that make it ideal for working with HTML, XML, and all other mark-up and natural languages. The Perl interpreter can be embedded into other systems such as web servers and database servers.
Tcl/Tk Programming Language
Tcl is a high-level, general-purpose, interpreted, dynamic programming language. It was designed with the goal of being very simple but powerful. Tcl casts everything into the mold of a command, even programming constructs like variable assignment and procedure definition. The popular combination of Tcl with the Tk extension is referred to as Tcl/Tk, and enables building a graphical user interface (GUI) natively in Tcl.
Vala Programming Language
Vala language is a programming language using modern high level abstractions without imposing additional runtime requirements and without using a different ABI compared to applications and libraries written in C. The Vala language uses the GObject type system and has additional code generation routines that make targeting the GNOME stack simple. Vala has many other uses where native binaries are required. Vala programming language is designed to allow access to existing C libraries, especially GObject-based libraries, without the need for runtime bindings. All that is needed to use a library with Vala language is an API file, containing the class and method declarations in Vala syntax. Vala currently comes with bindings for GLib and GTK+ and many others from the GNOME Platform. Speaking about the concept and syntax Vala is close related with Swift and C# but it implements a bit different flavour specific for Linux and Unix platforms.
Shell Scripting Language (Unix Shell Scripting)
The shell programming language is almost a standard for the Linux and Unix platforms. The shell scripting is a programming language similar with the powershell. The shell programming has small variations as implementation that differ between sh, ksh, ash, bash, dash and others but mostly they have all implemented the minimal standard shell language scripting. 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. The most popular shells that are mostly accepted as a standard for (unix) shell scripting are: `bash` (Bourne-Again Shell) and `ksh` (KornShell). Most of the other shells are implementing the bash or ksh shell syntax. Bash is a Unix shell and command language (mostly found on Linux) written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. Ksh (the KornShell), developed by David Korn at Bell Labs is a more traditional shell (mostly found on BSD/Unix) that complies with POSIX.2, Shell and Utilities, Command Interpreter. KornShell is backward-compatible with the Bourne shell.
