Raw extraction problems with dcraw

Hi,

I'm really a newbie in linux system! Please bear with me.
The problem is every time I run the shell script, it deletes all the files in the target directory and left one D source code type file with name: *.ppm.d.

Can anyone help me with this??
Thanks in advance!

what I'm trying to do is:
1. use dcraw to extract all *.raw in one directory. outputs are *.ppm. (The shell script let you type in the directory to work in)

2. remove all *.raw
3. doing a bit image processing with double.c(outputs are *.d)

4. remove all *.ppm files

5. remove *.d extension of all files

Here is the code:

Code:

#!/bin/sh
cd /home/pi/dcraw/
echo "Enter target directory: "
read filename


for file in "$filename/*.raw";
do
./dcraw "$file";
done


cd $filename
rm *.raw


for file in "$filename/*.ppm";
do
double $file > ${file}.d;
done


rm *.ppm


for file in "$filename/*.d";
do
mv -- "$file" "${file%%.d}";
done

LEARN ABOUT DEBIAN

dpkg::source::package

Dpkg::Source::Package(3)					   libdpkg-perl 					  Dpkg::Source::Package(3)

NAME

       Dpkg::Source::Package - manipulate Debian source packages

DESCRIPTION

       This module provides an object that can manipulate Debian source packages. While it supports both the extraction and the creation of source
       packages, the only API that is officially supported is the one that supports the extraction of the source package.

FUNCTIONS

       $p = Dpkg::Source::Package->new(filename => $dscfile, options => {})
	   Creates a new object corresponding to the source package described by the file $dscfile.

	   The options hash supports the following options:

	   skip_debianization
		   If set to 1, do not apply Debian changes on the extracted source package.

	   skip_patches
		   If set to 1, do not apply Debian-specific patches. This options is specific for source packages using format "2.0" and "3.0
		   (quilt)".

	   require_valid_signature
		   If set to 1, the check_signature() method will be stricter and will error out if the signature can't be verified.

	   copy_orig_tarballs
		   If set to 1, the extraction will copy the upstream tarballs next the target directory. This is useful if you want to be able to
		   rebuild the source package after its extraction.

       $p->get_filename()
	   Returns the filename of the DSC file.

       $p->get_files()
	   Returns the list of files referenced by the source package. The filenames usually do not have any path information.

       $p->check_checksums()
	   Verify the checksums embedded in the DSC file. It requires the presence of the other files constituting the source package. If any
	   inconsistency is discovered, it immediately errors out.

       $bool = $p->is_signed()
	   Returns 1 if the DSC files contains an embedded OpenPGP signature.  Otherwise returns 0.

       $p->check_signature()
	   Implement the same OpenPGP signature check that dpkg-source does.  In case of problems, it prints a warning or errors out.

	   If the object has been created with the "require_valid_signature" option, then any problem will result in a fatal error.

       $p->extract($targetdir)
	   Extracts the source package in the target directory $targetdir. Beware that if $targetdir already exists, it will be erased.
