t. e. In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code that is executed ...
Bash, short for Bourne-Again SHell, is a shell program and command language supported by the Free Software Foundation [ 2] and first developed for the GNU Project [ 3] by Brian Fox. [ 4] Designed as a 100% [ 5] free software alternative for the Bourne shell, [ 6][ 7][ 8] it was initially released in 1989. [ 9]
Shell script. Editing a FreeBSD shell script for configuring ipfirewall. A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. [ 1] The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program ...

Pipeline (Unix) A pipeline of three program processes run on a text terminal. In Unix-like computer operating systems, a pipeline is a mechanism for inter-process communication using message passing. A pipeline is a set of processes chained together by their standard streams, so that the output text of each process ( stdout) is passed directly ...
Scripting language. GDScript in Godot 3.4. In computing, a script is a relatively short and simple set of instructions that typically automate an otherwise manual process. The act of writing a script is called scripting. Scripting language or script language describes a programming language that is used for scripting. [ 1]
Unix shell. 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]
Control flow. v. t. e. In computer science, control flow (or flow of control) is the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated. The emphasis on explicit control flow distinguishes an imperative programming language from a declarative programming language.
