chmod (change mode) is a Unix/Linux command that sets file and directory permissions. It controls who can read, write, and execute files.

755 means: owner can read/write/execute (7), group can read/execute (5), others can read/execute (5). It's the standard permission for directories and scripts.

What's the difference between numeric and symbolic notation?

Numeric uses octal digits (755). Symbolic uses letters (rwxr-xr-x). They represent the same permissions — numeric is more compact, symbolic is more readable.
