Brief History
The .sh file extension is often associated with shell scripts, particularly those written for Unix-like operating systems. It originated with the development of Unix in the early 1970s. Stephen Bourne developed the original Unix shell, known as the Bourne Shell (sh). It became the default shell on Unix systems and included a scripting language for automating tasks. Users can begin creating shell scripts by writing a series of shell commands in a text file. It is still a fundamental component of Unix-like operating systems and is used extensively for a variety of scripting tasks, including automation and system administration. On many systems, Bash has emerged as the factory standard for shell scripting.
.sh | File Format
A .sh file is a scripting language command file containing a computer program that can be run by the Unix shell. It can contain a series of commands that run sequentially to perform operations such as file processing, program execution, and other similar tasks. These are run from the command line interface by the user or in batch mode to perform multiple operations simultaneously. Script files can be opened in text editors such as Notepad, Notepad++, Vim, Apple Terminal, and other similar applications on Windows, MacOS, and Linux.
