Hi All
Thanks a lot for all your suggestions and I have implemented 'summer cherry's logic.
Also, I tried to understand his logic, but not able to do so.
Could any one explain the below logic. I mean I know map and sort function, but don't know, how exactly below line will execute.
Quote:
print join "\n", map {$_->[1]} sort {$a->[0]<=>$b->[0]}map {my @tmp = split(",",$_); [$tmp[1],$tmp[0].",".$tmp[1]]} <DATA>;
With Regards,
Mysore Ganapati.

LEARN ABOUT DEBIAN
dh_movefiles
DH_MOVEFILES(1) Debhelper DH_MOVEFILES(1)
NAME
dh_movefiles - move files out of debian/tmp into subpackages
SYNOPSIS
dh_movefiles [debhelperoptions] [--sourcedir=dir] [-Xitem] file...]
DESCRIPTION
dh_movefiles is a debhelper program that is responsible for moving files out of debian/tmp or some other directory and into other package
build directories. This may be useful if your package has a Makefile that installs everything into debian/tmp, and you need to break that
up into subpackages.
Note: dh_install is a much better program, and you are recommended to use it instead of dh_movefiles.
FILES
debian/package.files
Lists the files to be moved into a package, separated by whitespace. The filenames listed should be relative to debian/tmp/. You can
also list directory names, and the whole directory will be moved.
OPTIONS
--sourcedir=dir
Instead of moving files out of debian/tmp (the default), this option makes it move files out of some other directory. Since the entire
contents of the sourcedir is moved, specifying something like --sourcedir=/ is very unsafe, so to prevent mistakes, the sourcedir must
be a relative filename; it cannot begin with a `/'.
-Xitem, --exclude=item
Exclude files that contain item anywhere in their filename from being installed.
file ...
Lists files to move. The filenames listed should be relative to debian/tmp/. You can also list directory names, and the whole directory
will be moved. It is an error to list files here unless you use -p, -i, or -a to tell dh_movefiles which subpackage to put them in.
NOTES
Note that files are always moved out of debian/tmp by default (even if you have instructed debhelper to use a compatibility level higher
than one, which does not otherwise use debian/tmp for anything at all). The idea behind this is that the package that is being built can be
told to install into debian/tmp, and then files can be moved by dh_movefiles from that directory. Any files or directories that remain are
ignored, and get deleted by dh_clean later.
