What is chmod?
chmod (change mode) is a Unix/Linux command used to set file and directory permissions. Permissions control who can read, write, or execute a file, and are assigned to three categories: owner, group, and others.
Numeric vs Symbolic Notation
Numeric notation uses three digits (e.g., 755) where each digit represents permissions for owner, group, and others. Each digit is the sum of read (4), write (2), and execute (1). Symbolic notation uses letters: r (read), w (write), x (execute), and - (no permission).
