Help:
* Usage:
~$ {$argv[0]} path=[path-to-dir] dest_path=[dest-subdir] move_processed=[move-processed-files] ext=[forced-ext]
where:
* path-to-dir - string - scan this path + 1 dir down
* dest-subdir - string - save results to "path-to-dir/dest-subdir/"
* move-processed-files - 0(default) or 1 - if not 1 - will not move the processed files
* forced-ext - string - override extensions from exifs with this one
* Examples:
** Split all *.img, *.bin and *.mov files in the current dir and 1 dir down, puts results to '0/':
~$ {$argv[0]}
** Split in /data/test + 1 dir down, create and move processed files to /data/test/processed for files in path and /data/test/any-found-subdir/processed for any files found in /data/test/any-found-subdir
~$ {$argv[0]} path=/data/test move_processed=1
** Split all *.img, *.bin and *.mov files in the current dir and 1 dir down, puts results to 'results/', override extensions with 'jpg':
~$ {$argv[0]} dest_path=results ext=jpg
