SIZE is an integer with an optional prefix and optional unit. The available units (K, M, G, T, P, E, Z, and Y) use the following format:

’KB’ => 1000 (kilobytes) ’K’ => 1024 (kibibytes) ’MB’ => 1000*1000 (megabytes) ’M’ => 1024*1024 (mebibytes) ’GB’ => 1000*1000*1000 (gigabytes) ’G’ => 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:

’+’ => extend by ’−’ => reduce by ’<’ => at most ’>’ => at least ’/’ => round down to multiple of ’%’ => round up to multiple of
