- description:
- Use when writing a Bash script. Covers the template, conventions, and required patterns.
Template
Start from the template at assets/template.sh. Copy it exactly and fill in the specific logic.
Conventions
- File:
<name>.shwith kebab-case (e.g.,extract-pr-number.sh) - Make the file executable (
chmod +x) - Flag-based arguments using
--flag-name(kebab-case). Only use positional args for very simple cases. - Full variable names (
directory, notdir) - Exit
0for success,1for errors - stdout for primary output, stderr for errors/warnings/progress messages
Required patterns
set -euo pipefailat the top of every scriptprint_help()function for help output--helpflag must be the first case in argument parsing- All error messages must start with
Error:and go to stderr (>&2) - Always print help to stderr when validation fails or unknown options are provided
- Always quote variable expansions (
"$variable") - Validate required flags after the parsing loop completes
- Invalid options must print
Error: The option <option> is invalid.
