For managing large and variable command lines, several tools can help:

1. Tome (github.com/laktak/tome): Manages playbooks and recurring commands.
2. Just (github.com/casey/just): Similar to Make, focused on commands.
3. Atuin (atuin.sh): Enhances shell command history management.
4. Simple bash scripts with fuzzy search using fzf.
5. Invoke (pyinvoke.org): For complex Python-based task execution.
