Build Reliable Bash Scripts
Shell automation can fail when inputs, errors, cleanup, and tests are overlooked. This workflow guides structured design, defensive implementation, testing, and documentation.

Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "bash-scripting" from https://skillstore.io/skills/sickn33-bash-scripting.md and its manifest at https://skillstore.io/api/skills/sickn33-bash-scripting/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "bash-scripting". Plan a backup script for a directory and remote destination.
Expected outcome:
- Defines required source and destination inputs.
- Validates paths, tools, permissions, and available space.
- Plans cleanup, logging, retries, exit codes, and rollback behavior.
- Lists ShellCheck checks and Bats test scenarios.
Using "bash-scripting". Harden a deployment script that has inconsistent error handling.
Expected outcome:
A focused review identifies missing strict mode, unchecked commands, unsafe argument handling, incomplete cleanup, and absent rollback tests.
Using "bash-scripting". Document a maintenance script for team use.
Expected outcome:
The result covers purpose, dependencies, options, examples, exit codes, logs, testing steps, and troubleshooting guidance.
Security Audit
SafeAll 37 static findings are false positives caused by Markdown backticks, code fences, benign shell substitutions, and a Bats testing checklist item. The skill is documentation-only and shows no prompt injection, network reconnaissance, data exfiltration, or malicious command execution intent.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Automate System Operations
Create maintainable administration scripts with validation, logging, cleanup, and predictable exit codes.
Build Deployment Utilities
Design deployment scripts with strict failure handling, rollback planning, tests, and operational documentation.
Standardize Shell Contributions
Apply consistent structure, ShellCheck rules, Bats tests, and documentation to team shell scripts.
Try These Prompts
Plan a Bash script that [goal]. Identify inputs, outputs, dependencies, errors, and success criteria before writing the implementation.
Create a Bash script for [task]. Include strict mode, validated arguments, usage text, structured logging, cleanup traps, and meaningful exit codes.
Review this Bash script for unsafe expansion, missing validation, weak error handling, cleanup failures, and unclear logging. Propose focused corrections.
Design a production validation plan for this Bash script. Include ShellCheck, Bats tests, edge cases, failure injection, rollback checks, and documentation updates.
Best Practices
- Define inputs, outputs, permissions, and failure behavior before implementation.
- Quote expansions, validate external data, and use cleanup traps for temporary resources.
- Run ShellCheck and Bats tests in the same environment used for deployment.
Avoid
- Do not copy the starter template without adapting validation and dependencies.
- Do not suppress command failures without logging context and handling recovery.
- Do not deploy generated automation before testing permissions, edge cases, and rollback behavior.
