The available units (K, M, G, T, P, E, Z, and Y) use the following format:
    \*(AqKB\*(Aq => 1000 (kilobytes)
    \*(AqK\*(Aq => 1024 (kibibytes)
    \*(AqMB\*(Aq => 1000*1000 (megabytes)
    \*(AqM\*(Aq => 1024*1024 (mebibytes)
    \*(AqGB\*(Aq => 1000*1000*1000 (gigabytes)
    \*(AqG\*(Aq => 1024*1024*1024 (gibibytes)
SIZE may also be prefixed by one of the following to adjust the size of each
file based on its current size:
    \*(Aq+\*(Aq => extend by
    \*(Aq\-\*(Aq => reduce by
    \*(Aq<\*(Aq => at most
    \*(Aq>\*(Aq => at least
