Why CommandBox?
# CLI Frameworks
{code}
Let's Look At Code
- Interactive inputs
- Free-form prompt
- Confirmation (y/n)
- Multiple choice
- Hot-key
User Input
# CLI Inputs
{code}
Interactive Inputs
- Make it DRY
- Write it like any modern CFML
Helper Methods

Helper Methods
- Run other CommandBox commands
- Run shell commands
- Run other binaries/executables
- Full filesystem interaction
Running Commands & Filesystem Resources
# Modules/DI
{code}
Shell and Filesystem
- Write and Inject Modules (ColdBox style)
- Install external Modules
