Writes, reviews and fixes shell scripts (bash and sh) so they are safe, portable and testable. Use whenever the user asks for a bash or sh script, shares one to review or debug, hits errors like unbound variable, command not found, bad interpreter or broken quoting, wants a script to run in Termux, Linux and macOS, or asks to automate a task from the command line, even if they only say "write me a script that does X". Lints with a script and uses a safe template with dry-run and cleanup.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# shell-scripting
Shell scripts fail in quiet, destructive ways: an empty variable in `rm -rf`, a failed `cd`, unquoted spaces. This skill writes scripts that stop early, clean up after themselves and can be tested without risk.

## When to use
- Writing a new automation script
- Reviewing, debugging or hardening an existing script
- A script works on one machine but not another (Linux, macOS, Termux, `sh` versus `bash`)
- Errors about quoting, unbound variables, `\r`, interpreters or permissions
## Workflow
1. **Clarify the task** in one sentence: inputs, outputs, what may be deleted or changed, where it runs (Fedora, Termux, CI). Ask only what you cannot infer.
2. **Start from the template** in `references/safe-patterns.md`: strict mode, usage text, `--dry-run`, `mktemp` with `trap` cleanup, quoted expansions.
3. **Write small, named functions** and keep data on stdout and messages on stderr.

How to install
mdr add mehranqadirian/skills/shell-scripting@sha256:a9f72374fdc8b31cThe line at the top of this page pins the label git:20261104.b07e2c3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
