chmod 755 Explanation 1. Understand chmod notation The command `chmod` uses octal numbers to set file permissions. Each digit represents different permissions for owner, group, and others. 2. Decode the permission digits - First digit (owner): 7 = read (4) + write (2) + execute (1) = 7 - Second digit (group): 5 = execute (1) + read (4) = 5 - Third digit (others): 5 = execute (1) + read (4) = 5
