Check a partition for bad blocks before creating the swap area

sudo mkswap {{[-c|--check]}} {{path/to/file}}

sudo mkswap {{[-L|--label]}} {{label}} {{/dev/sdXY}}

Use the specified UUID

sudo mkswap {{[-U|--uuid]}} {{clear|random|time|UUID_value}}

Set up a swap file (for btrfs, see `tldr btrfs filesystem` instead)

sudo mkswap {{[-s|--size]}} {{file_size}} {{[-F|--file]}} {{path/to/swapfile}}
