🔬Technical Introduction
Core ConceptFile permissions control access to files and directories. Three types: owner, group, and others. Each has read, write, and execute permissions.
Best PracticesUse 755 for executables, 644 for regular files, 600 for sensitive files. Avoid 777 unless necessary for security.
