Module shell_exec 

Cross-platform shell execution

Provides a unified interface for executing shell commands across platforms:

• Unix: Uses sh -c (resolved via PATH)
• Windows: Uses Git Bash (requires Git for Windows)

This enables hooks and commands to use the same bash syntax on all platforms. On Windows, Git for Windows must be installed — this is nearly universal among Windows developers since git itself is required.
