Format2USB - Quick Way to Format USB/HDD/SDCards via Commandline

A couple of functions i created to format my drives. It will delete existing partitions and create just a single partitions that fills the whole drive, then formats it to whatever filesystem you choose.

I could of used just mkfs to format but from my experience linux likes to have at least one partition so that is why we used fdisk to create a partition before we format with mkfs.

add to ~/.bashrc or ~/.zshrc
