files Files to test on. File names have the following fomat:

[ size: ] path

[ free% [ max size ] : ] path

If no size is specified, the files must exist
|

and the contents will be overwritten if testing write or
|

writea system calls. If a size is supplied, an attempt to
|

create/grow/shrink path to the desired size will be made.
|

size is an integer which defaults to bytes, but may be
|
||||
suffixed by 'b', 'k', or 'm' for blocks (4096 byte units),
|
||||
kilobytes (1024 byte units), or megabytes (2^20 byte units).
|

|
||||
If the size is a percentage, df is used to find how much
|
||||
free space there is (in blocks), and uses that. The maximum
|
||||
size is implied to be in blocks.
