Bash

What This Skill Does

The Bash skill provides OpenClaw with the capability to generate, debug, and optimize robust Bash scripts. It focuses on writing POSIX-compliant or Bash-specific code that adheres to industry best practices, such as proper quoting, safe parameter expansion, and defensive programming. This skill acts as a technical advisor that understands the nuances of subshells, word splitting, and globbing, ensuring your automation scripts don't fail due to common pitfalls like unquoted variables or space-sensitive filenames.

Installation

To integrate this skill into your agent, run the following command in your terminal: clawhub install openclaw/skills/skills/ivangdavila/bash

Use Cases

This skill is ideal for sysadmins, DevOps engineers, and developers who need to automate repetitive CLI tasks. It is perfect for writing robust startup scripts, cleanup utilities, log rotation routines, and data processing pipelines. Whether you are refactoring legacy scripts or building new complex automation, this skill ensures your code is maintainable, secure, and error-proof.

Example Prompts

1. "Create a Bash script that searches for files older than 30 days in a given directory, archives them into a tarball, and ensures the script handles filenames with spaces correctly."
2. "Review this script for common quoting traps: if [ $filename = 'test' ]; then cat $filename; fi. Rewrite it using best practices."
3. "Write a function that accepts a parameter, assigns a default value if it's unset, and validates that the variable is not empty using parameter expansion."

Tips & Limitations

To get the most out of this skill, always leverage [[ ]] over [ ] for its advanced pattern matching and safety features. Remember that set -e and set -u are your best friends for catching unexpected behavior early. Be cautious when piping command outputs into while loops, as subshells can clear your variables; use process substitution instead. While this skill provides excellent code, always test generated scripts in a sandbox environment before deploying them to production, as script execution can involve file system modifications or data deletion.
