Set up a Linux swap area on a device or in a file. Note: path/to/file can either point to a regular file or a swap partition. More information:

  • Set up a given swap area:

sudo mkswap {{path/to/file}}

  • Check a partition for bad blocks before creating the swap area:

sudo mkswap -c {{path/to/file}}

  • Specify a label for the partition (to allow swapon to use the label):

sudo mkswap -L {{label}} {{/dev/sda1}}
