Knowra Shell script Shell script A shell script is a text file containing commands interpreted and executed by a command-line shell. It can automate tasks and coordinate other programs.
Command-line interface : A text-based interface in which users interact with a computer by entering commands. A shell script automates commands normally entered through this interface.
Shell command : An instruction interpreted by a command-line shell, often invoking a program or shell feature. A script is composed of shell commands arranged for execution.
Task automation : The use of software to perform recurring tasks with limited human intervention. Shell scripts automate routine sequences of operating-system commands.
Python (programming language) : A high-level, general-purpose programming language with a large standard library. Python often replaces shell scripts when logic, portability, or data handling grows complex.
Shell (computing) : A program that interprets commands and provides an interface to an operating system. The shell parses and executes the script's commands.
Shell quoting : Syntax that controls how a shell interprets spaces, special characters, and expansions in text. Correct quoting keeps values with spaces or special characters intact.
Build automation : The automated process of compiling, testing, and packaging software from source files. Build scripts coordinate compiler and packaging commands into repeatable workflows.
PowerShell : A command-line shell and scripting language built around objects and the .NET ecosystem. PowerShell offers a different scripting model, especially across Windows administration.
Shell expansion : The transformations a shell applies to command text before executing it, including variable and wildcard expansion. Expansions substitute values and patterns as each command is prepared.
Shell redirection : Shell syntax that changes where a command reads input or sends output and errors. Redirection lets scripts save output, read files, and suppress or capture errors.
