Bashstyle

Bashstyle is a programming style and set of conventions for writing shell scripts in the Bash programming language. It is designed to improve the readability, maintainability, and portability of Bash scripts. The Bashstyle guidelines were created by Patrick Callahan and have been widely adopted within the Bash scripting community.

The key principles of Bashstyle include:

1. Use meaningful variable names: Variable names should be descriptive and follow a consistent naming convention, such as using lowercase letters and underscores.

2. Use functions: Functions should be used to encapsulate reusable code, making scripts more modular and easier to understand.

3. Use quotes: Quotes should be used around variable expansions and command substitutions to prevent word splitting and globbing.

4. Use local variables: Variables should be declared as local within functions to avoid unintended side effects.

5. Use exit codes: Scripts should use meaningful exit codes to indicate success or failure, and handle errors gracefully.

6. Use comments: Comments should be used to explain the purpose of code and improve readability.

Bashstyle is not an official standard, but it has become a widely accepted best practice for Bash scripting. By following the Bashstyle guidelines, developers can create more robust, maintainable, and portable Bash scripts.
