Is it compatible with POSIX sh?

While the primary focus is on Bash 4+, the skill provides specific notes and alternative headers for maintaining POSIX shell portability when required.

Does it support unit testing for shell scripts?

Absolutely. It provides standardized implementation patterns for bats-core, ensuring your shell logic is verifiable and maintainable.

How does it handle complex argument parsing?

The skill utilizes a standardized getopts template that safely handles flags, option arguments, and positional parameters while providing automatic usage documentation.

How does this skill improve script safety?

It enforces the 'set -euo pipefail' header, mandates variable quoting to prevent word splitting, and provides robust cleanup trap patterns for temporary resources.

Can this help with cross-platform shell scripts?

Yes, it includes specific logic for detecting OS environments and handling tool differences between macOS (BSD) and Linux (GNU) versions of commands like sed, date, and stat.
