Bash Pro

If you're writing shell scripts for production environments or CI/CD pipelines, this skill enforces defensive patterns that prevent the usual footguns. It defaults to strict mode with proper error trapping, safe argument parsing with getopts, and comprehensive input validation. The approach is opinionated about things like NUL-safe file iteration, proper quoting to avoid word splitting, and using arrays instead of parsing ls output. It also integrates testing with Bats and static analysis with ShellCheck, which honestly should be standard but often isn't. The focus on portability across Linux, macOS, and BSD variants is useful if you maintain scripts that run in different environments.
