prompt templates

Turn fragile one-off CLI commands into reliable, shareable Bash workflows with prompts, safe defaults, and previews. This guide shows how to wrap tasks, speed selection with fzf, add guardrails with dialog/whiptail, and drive choices from JSON via jq, with install steps for apt/dnf/zypper and ready-to-use scripts (backup, git branch, env runs, log tails), plus tips for organizing, versioning, and real-world automations to reduce errors and speed onboarding.

Turn your Bash prompt into a productive HUD: learn why prompt templates reduce mistakes and mental load, then build a fast, minimal PS1 with colors, exit status, jobs, a newline, and Git via __git_ps1. Compare Starship (cross-shell, smart defaults) and Powerline (segmented, font-based), add per-host/project cues with direnv, and apply speed/testing tips to keep prompts portable, readable, and context-aware.
