Question 1

What does chmod 755 mean?

Accepted Answer

chmod 755 gives the owner full permissions (read, write, execute = 7), while group and others get read and execute (5). This is the typical permission for web directories and scripts.

Question 2

What is the difference between numeric and symbolic notation?

Accepted Answer

Numeric notation uses three digits (e.g., 644), where each digit represents permissions for owner, group, and others. Symbolic notation uses letters like rwxr--r-- to show the same information.
