Claude Code Bash Patterns

A systematic reference for orchestrating bash commands in Claude Code through hooks, command chaining, and session persistence. You're getting patterns for the five core scenarios (sequential with &&, parallel tool calls, stateful sessions, background processes, and PreToolUse hooks), plus git workflow automation and CLI tool integration. The 55% token savings comes from teaching you when to chain commands versus fire parallel tool calls, and the hooks let you inject logging or security checks before every bash execution. Load this when you're setting up automated workflows, need to understand why your commands are timing out, or want to stop re-explaining that git operations should chain with && instead of semicolons.
