Mount a directory on RAM.

Mount a directory completely on RAM. Everything will be wiped out on reboot.

mount -o size=<x>G -t tmpfs none <dir_name>

Explanation

size=<x>G: Sets the directory size in RAM (replace with GB, e.g., size=4G for a 4GB virtual directory).

-t tmpfs: Specifies tmpfs as the RAM-based filesystem.

none: Represents the virtual directory in RAM, not tied to any physical device.

<dir_name>: Path to the directory where you'll access the RAM directory.
