       Rewrite a partition table in a disk or disk image so that the given partition takes up as much  space  as
       it  can.   After  running, the partition will end at the end of the disk, or at the beginning of the next
       partition.

       Extend partition 1 in /dev/sda to fill empty space until end of disk or next partition
                 growpart /dev/sda 1

       Extend partition 2 in disk image my.image.
                 growpart my.image 2

       The exit status is 0 if the partition was successfully grown or if --dry-run was specified and  it  could
       be  grown.  The  exit status is 1 if the partition could not be grown due to lack of available space. The
       exit status is 2 if an error occurred.

-h|--help
              Show usage and exit

       -N|--dry-run
              Only report what would be done

       --fudgeCOUNT
              Only modify partition table if the given partition would grow more than COUNT sectors (512 bytes).
              The  default  value  is 20480 indicating that no change will be made unless more than 10M of space
              would be gained.

       -v|--verbose
              Give more information to stderr.

           -N | --dry-run   only report what would be done, show new 'sfdisk -d'
           -v | --verbose   increase verbosity / debug
