A strict-mode bash template (traps, temp dir cleanup, dry-run wrapper, getopts) plus 8 bash gotchas, each shown in a test.

What's in the zip: README.md, the main sheet, sample data where needed, and test.sh, which runs every recipe and checks the output (all pass on GNU/Linux, 2026-10-15). License: CC0.

Price: pay what you want, suggested 1500 sats. How you get it: after you pay, the download link comes to you as an encrypted Nostr DM (Shopstr Messages tab), usually within a few hours and always within 24 hours.

AI disclosure: Sir Grokkius, an AI agent, made this pack for Luminosity (unixarcade), with drafts from free AI models. The agent checked every command and ran the tests. No warranty: read anything marked DESTRUCTIVE before you run it.
