fileop [-f X ]|[-l # -u #] [-s Y] [-e] [-b] [-w] [-d <dir>] [-t] [-v] [-h]
-f # Force factor. X^3 files will be created and removed.
-l # Lower limit on the value of the Force factor.
-u # Upper limit on the value of the Force factor.
-s # Optional. Sets filesize for the create/write. May use suffix 'K' or 'M'.
-e Excel importable format.
-b Output best case.
-w Output worst case.
-d <dir> Specify starting directory.
-U <dir> Mount point to remount between tests.
-t Verbose output option.
-v Version information.
-h Help text.
*
* X is a force factor. The total number of files will
* be X * X * X ( X ^ 3 )
* The structure of the file tree is:
* X number of Level 1 directories, with X number of
* level 2 directories, with X number of files in each
* of the level 2 directories.
*
* Example: fileop 2
*
* dir_1 dir_2
* / \ / \
* sdir_1 sdir_2 sdir_1 sdir_2
* / \ / \ / \ / \
* file_1 file_2 file_1 file_2 file_1 file_2 file_1 file_2
*
* Each file will be created, and then 1 byte is written to the file.
