Frequently Asked Questions
What does chmod 755 mean?
chmod 755 means the owner has full permissions (read, write, execute), while the group and others can only read and execute. This is the standard permission for web server directories and executable scripts.
What is the difference between numeric and symbolic notation?
Numeric notation uses three octal digits (e.g., 755) where each digit represents a sum: read=4, write=2, execute=1. Symbolic notation uses letters: r (read), w (write), x (execute), - (none), grouped by owner, group, and others (e.g., rwxr-xr-x).
What are common chmod values?
644 — files (owner reads/writes, others read only). 755 — directories and scripts (owner full, others read/execute). 600 — private files (owner only). 777 — full access for everyone (avoid in production).
