foremost(8) - Recover files using their headers, footers, and data structures
-h     Show a help screen and exit.
-V     Show copyright information and exit.
-d     Turn on indirect block detection, this works well for Unix file systems.
-T     Time stamp the output directory so you don't have to delete the output dir when  running  multiple
-v     Enables  verbose  mode. This causes more information regarding the current state of the program to
       be displayed on the screen, and is highly recommended.
-q     Enables quick mode. In quick mode, only the start of each sector is searched for matching headers.
       That  is,  the  header  is  searched  only up to the length of the longest header. The rest of the
       sector, usually about 500 bytes, is ignored. This mode makes foremost run considerably faster, but
       it may cause you to miss files that are embedded in other files. For example, using quick mode you
       will not be able to find JPEG images embedded in Microsoft Word documents.

       Quick mode should not be used when examining NTFS file systems.  Because  NTFS  will  store  small
       files inside the Master File Table, these files will be missed during quick mode.
-Q     Enables Quiet mode. Most error messages will be suppressed.
-w     Enables write audit only mode.  No files will be extracted.
-a     Enables write all headers, perform no error detection in terms of corrupted files.
-b number
       Allows you to specify the block size used in foremost.  This is relevant for file naming and quick
       searches.  The default is 512.       ie.  foremost -b 1024 image.dd
-k number
       Allows you to specify the chunk size used in foremost.  This can improve speed if you have  enough
       RAM  to  fit the image in.  It reduces the checking that occurs between chunks of the buffer.  For
       example if you had > 500MB of RAM.       ie.  foremost -k 500 image.dd
-i file
       The file is used as the input file.  If no input file is specified or the  input  file  cannot  be
       read then stdin is used.
-o directory
       Recovered files are written to the directory directory.
-c file
       Sets  the  configuration  file  to  use.  If  none is specified, the file "foremost.conf" from the
       current directory is used, if that doesn't exist then "/etc/foremost.conf" is used. The format for
       the  configuration file is described in the default configuration file included with this program.
       See the CONFIGURATION FILE section below for more information.
-s number
       Skips number blocks in the input file before beginning the search for headers.       ie.  foremost
       -s 512 -t jpeg -i /dev/hda1
