swap_file_size_from_csv() ⇒ Any

Given a csv of swap files and sizes, split by pipe (||), we can determine the size in bytes of the swapfile Will return false if the swapfile is not found in the csv Examples:

get_swap_file_size_from_csv('/mnt/swap.1','/mnt/swap.1||1019900,/mnt/swap.1||1019900')

Would return: 1019900

get_swap_file_size_from_csv('/mnt/swap.2','/mnt/swap.1||1019900,/mnt/swap.1||1019900')
