Bash and Awk for creating directories and moving files
I have a security system that FTPs the camera files to my machine, however I want to sort the pictures (taken every 30s) into directories by hour.

Every picture uses the following file format.
yymmddhhmmsstt.jpg (where tt is the milliseconds)

I am thinking the for loop is best

for file in *.jpg
do
?here?
done

I know its very vague, however the end result is I am guessing use awk (or better?) to create variables from the yy mm dd hh parts of the filenames, then creating directories based on those variables nested with a check to see if the directory exists, creating the directory if it doesnt.

i.e. (the way I imagine it working, I dont know how to actually construct the script to do this)

for file in 08072400123200.jpg
do
%y=08
%m=07
%d=24
%h=00
if not exist directory %y - mkdir %y
if not exist directory %y/%m - mkdir %y/%m
if not exist directory %y/%m/%d - mkdir %y/%m/%d
if not exist directory %y/%m/%d/%h - mkdir %y/%m/%d/%h
mv %y%m%d%h*.jpg %y/%m/%d/%h
done

Moving all the pictures taken within that hour into the respective subdirectories.

Any help would be much appreciated.

sane-dc25

sane-dc25(5)						   SANE Scanner Access Now Easy 					      sane-dc25(5)

NAME

       sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras

DESCRIPTION

       The sane-dc25 library implements a SANE (Scanner Access Now Easy) backend that provides access to Kodak DC20 and DC25 cameras.  At present,
       only the DC25 has been tested, but since the code is based on a DC20 interface program, it is likely to work for that model also.

DEVICE NAMES

       The current version of the backend only allows one camera to be connected.  The device name is always "0".

CONFIGURATION

       The contents of the dc25.conf specify the serial port and baud rate to use.  The baud rate specifies the maximum rate to  use  while  down-
       loading	pictures.   (The  camera is always initialized using 9600 baud, then switches to the higher rate).  On my 90MHz Pentium, I usually
       have no problems downloading at 115200 baud as long as the system is not excessively busy and the "interrupt-unmask flag" is set in the IDE
       driver (hdparm -u1).  Supported baud rates are: 9600, 19200, 38400, 57600, and 115200.

       The  dumpinquiry  line causes some information about the camera to be printed to stderr during startup.	Note:  This is not compatible with
       saned, so make sure you don't have any dumpinquiry lines if you are using saned (i.e. scanning on a remote machine using a network).

       Empty lines and lines starting with a hash mark (#) are ignored.  A sample configuration file is shown below:

	      port=/dev/ttyS0
	      # this is a comment
	      baud=115200
	      dumpinquiry

FILES

       /etc/sane.d/dc25.conf
	      The backend configuration file (see also description of SANE_CONFIG_DIR below).

       /usr/lib64/sane/libsane-dc25.a
	      The static library implementing this backend.

       /usr/lib64/sane/libsane-dc25.so
	      The shared library implementing this backend (present on systems that support dynamic loading).

ENVIRONMENT

       SANE_CONFIG_DIR
	      This environment variable specifies the list of directories that may contain the configuration file.  Under  UNIX,  the  directories
	      are  separated  by a colon (`:'), under OS/2, they are separated by a semi-colon (`;').  If this variable is not set, the configura-
	      tion file is searched in two default directories: first, the current working directory (".") and then in /etc/sane.d.  If the  value
	      of the environment variable ends with the directory separator character, then the default directories are searched after the explic-
	      itly specified directories.  For example, setting SANE_CONFIG_DIR to "/tmp/config:" would result in directories  "tmp/config",  ".",
	      and "/etc/sane.d" being searched (in this order).

       SANE_DEBUG_DC25
	      If  the library was compiled with debugging support enabled, this environment variable controls the debug level for this backend.  A
	      value of 128 requests maximally copious debug output; smaller levels reduce verbosity.

BUGS

       Known bugs/limitations are:

       I haven't figured out how to trigger an option reload following a "scan."  This causes problems when a new picture is snapped for  example,
       the slider that is used to select the picture from the camera may not be updated immediately.

       More  general  comments,  suggestions,  and  inquiries  about  frontends  or  SANE  should  go  to  the	SANE  Developers mailing list (see
       http://www.sane-project.org/mailing-lists.html for details).  You must be subscribed to the list, otherwise your mail won't be sent to  the
       subscribers.
