What is .sh?

.sh files contain a series of commands written in a scripting language for a command-line interpreter (shell), such as Bash (Bourne Again Shell), Zsh, or sh. They are used to automate tasks, install software, and manage system configurations on Unix-like operating systems (Linux, macOS).

This quick guide explains when to use .sh files, how to open them on any device, and how to share them instantly with FileXhost.

When to use .sh files

You want to automate repetitive tasks (e.g., backing up files, renaming photos).
You are setting up a development environment or server.
You are creating a deployment pipeline (CI/CD).
You need to chain multiple command-line tools together.

How to open .sh files

SH files are plain text and can be edited in any text editor. To run them, you execute them in a terminal using a shell interpreter.

Algorithm details

Shell scripts are interpreted line-by-line by the shell. They can execute system commands, define variables, use control structures (if/else, loops), and define functions. The shebang line (e.g., `#!/bin/bash`) at the top tells the system which interpreter to use.

Browser & platform support

Direct: Not supported by browsers.
WebContainers: Modern technologies like WebContainers can run some shell commands directly in the browser.

Format comparison

Feature	Details
Power	Can control the entire operating system, manipulate files, and start/stop processes.
Portability	Scripts written for standard `sh` work on almost any Unix system. Bash scripts work on Linux, macOS, and Windows (via WSL).
Simplicity	Great for gluing together other programs ('piping' output from one to another).

How to create sh files

Text Editors: Save file as 'script.sh'.
CLI: 'touch script.sh' then 'chmod +x script.sh' to make it executable.
Echo: 'echo "echo Hello" > script.sh'.

How to convert sh files

FileXhost: Upload to share scripts.
Compilers: Tools like 'shc' can compile scripts into binaries for obfuscation.

Frequently asked questions

How do I run a .sh file?

Open your terminal and type `bash script.sh` or `./script.sh` (if it has executable permissions).

What is chmod +x?

It's a command that makes a file executable. You usually need to run `chmod +x script.sh` before you can run it with `./script.sh`.

Can I run .sh files on Windows?

Yes, using Git Bash, WSL (Windows Subsystem for Linux), or Cygwin.
