Bash
What it does
Writes, debugs, and hardens Bash shell scripts — quoting, arrays, strict mode, traps, argument parsing, and macOS/Linux portability. Use when writing or reviewing any script, one-liner, cron job, deploy script, container entrypoint, or CI step; when a script breaks on spaces in filenames, exits silently, ignores set -e, hangs, or returns the wrong exit code; when quoting, IFS, globs, arrays, heredocs, process substitution, trap, getopts, or mapfile misbehave; when shellcheck flags SC2086 and friends; when unbound variable, bad substitution, command not found, ambiguous redirect, or unexpected end of file show up; when a script works by hand but fails under cron, systemd, sudo, or a CI runner; or when porting between macOS bash 3.2, GNU/Linux, WSL, and POSIX sh. Not for interactive zsh or fish configuration, not for PowerShell, and not for host-level cron, systemd, or permission failures (linux).
