You might want to read my little
introduction to find for a starter on how to use "find".
"xargs" is not necessary, just use "-ls" as find option, it does quite the same. In general, it is advisable to use "find ... -exec .." instead of "find ... | xargs" most of the times.
i hope this helps.

LEARN ABOUT DEBIAN
dpkg-name
dpkg-name(1) dpkg utilities dpkg-name(1)
NAME
dpkg-name - rename Debian packages to full package names
SYNOPSIS
dpkg-name [option...] [--] file...
DESCRIPTION
This manual page documents the dpkg-name program which provides an easy way to rename Debian packages into their full package names. A full
package name consists of package_version_architecture.package-type as specified in the control file of the package. The version part of the
filename consists of the upstream version information optionally followed by a hyphen and the revision information. The package-type part
comes from that field if present or fallbacks to deb.
OPTIONS
-a, --no-architecture
The destination filename will not have the architecture information.
-k, --symlink
Create a symlink, instead of moving.
-o, --overwrite
Existing files will be overwritten if they have the same name as the destination filename.
-s, --subdir [dir]
Files will be moved into a subdirectory. If the directory given as argument exists the files will be moved into that directory oth-
erwise the name of the target directory is extracted from the section field in the control part of the package. The target directory
will be `unstable/binary-architecture/section'. If the section is not found in the control, then `no-section' is assumed, and in
this case, as well as for sections `non-free' and `contrib' the target directory is `section/binary-architecture'. The section field
isn't required so a lot of packages will find their way to the `no-section' area. Use this option with care, it's messy.
-c, --create-dir
This option can used together with the -s option. If a target directory isn't found it will be created automatically. Use this
option with care.
-?, --help
Show the usage message and exit.
-v, --version
Show the version and exit.
EXAMPLES
dpkg-name bar-foo.deb
The file `bar-foo.deb' will be renamed to bar-foo_1.0-2_i386.deb or something similar (depending on whatever information is in the
control part of `bar-foo.deb').
find /root/debian/ -name '*.deb' | xargs -n 1 dpkg-name -a
All files with the extension `deb' in the directory /root/debian and its subdirectory's will be renamed by dpkg-name if required
into names with no architecture information.
find -name '*.deb' | xargs -n 1 dpkg-name -a -o -s -c
Don't do this. Your archive will be messed up completely because a lot of packages don't come with section information. Don't do
this.
dpkg-deb --build debian-tmp && dpkg-name -o -s .. debian-tmp.deb
This can be used when building new packages.
BUGS
Some packages don't follow the name structure package_version_architecture.deb. Packages renamed by dpkg-name will follow this structure.
Generally this will have no impact on how packages are installed by dselect(1)/dpkg(1), but other installation tools might depend on this
naming structure.
