# Dependency Checker - Analyze file dependencies
|
||||
#
|
||||
# Purpose: Check for dependencies between files to inform commit ordering
|
||||
# Version: 1.0.0
|
||||
# Usage: ./dependency-checker.sh [files...]
|
||||
# If no files specified, analyzes all changed files
|
||||
# Returns:
|
||||
# Exit 0: Success
|
||||
# Exit 1: Error
|
||||
# Exit 2: Invalid parameters
|
||||
#
|
||||
# Dependencies: git, bash 4.0+, grep
