Bash Code Style

Generally follows https://google.github.io/styleguide/shellguide.html

And the following rules have higher priority.

Editor Settings

• Your editor must be able to recognize the .editorconfig file in project.
• Shellcheck must be installed, and your editor must support it.

File naming

• All filenames must match the regex [-_a-z0-9], except other particular files (like Dockerfile).
• All script filenames must end with .bash.

File Header

• For executable files, put #!/usr/bin/env bash at the top of file.
• For .bats files, put #!/usr/bin/env bats at the top of file.
• No shebang for non-executable files.

Test

• Use bats for unit testing.

Rules

• No function key. Function declaration func() {...} is preferred over function func() {...}.
