Use grealpath for Path Operations

Rule (CRITICAL)

ALWAYS use grealpath command for:

• Calculating relative paths between files/directories
• Converting relative paths to absolute paths
• Resolving symbolic links to absolute paths

Relative Path Calculation

Use grealpath --relative-to=<base> to calculate relative paths:

# Calculate relative path from base directory to target
grealpath --relative-to=/home/user /home/user/test
# Output: test
