Bash Scripting Workflow

Overview

Specialized workflow for creating robust, production-ready bash scripts with defensive programming patterns, comprehensive error handling, and automated testing.

When to Use This Workflow

Use this workflow when:

• Creating automation scripts
• Writing system administration tools
• Building deployment scripts
• Developing backup solutions
• Creating CI/CD scripts

Scope and execution

Choose the phases that match the user’s task; this document is an index, not an instruction to run every listed skill. Read a selected skill before using it. Respect repository and user constraints. Cloud calls, host configuration, publishing, destructive operations and spending require the applicable authorization; a workflow checklist does not grant it.

The template is a starting point, not a completed script: it does not implement argument parsing or rollback. Validate paths, quote expansions, test in a disposable directory, and make retries bounded and safe for the specific command. Never log credentials or imply strict mode catches every failure.

Script Template

#!/usr/bin/env bash
set -euo pipefail

SCRIPT_NAME=$(basename -- "$0")
readonly SCRIPT_NAME
SCRIPT_DIR=$(cd -- "$(dirname -- "$0")" && pwd)
readonly SCRIPT_DIR

log() { echo "[$(date '+%Y-%m-%d %H:%M:%S')] $*"; }
error() { log "ERROR: $*" >&2; exit 1; }

usage() { cat <<EOF
Usage: $SCRIPT_NAME [OPTIONS]
Options:
    -h, --help      Show help
    -v, --verbose   Verbose output
EOF
}

main() {
    log "Script started"
    # Implementation
    log "Script completed"
}

main "$@"

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
