remember you are redirecting output to a file and then moving the file back to the original
what if the file sizes are of the order of tens of MBs.
secondly, the shell script would compulsorily do it for all the files in the directory.
but while using a file, you can customize your renaming process.

DH-EXEC-INSTALL(1)						      dh-exec							DH-EXEC-INSTALL(1)

NAME
dh-exec-install - Install (and possibly rename) files. SYNOPSIS
#! /usr/bin/dh-exec debian/default.conf => /etc/my-package/start.conf usr/bin/* DESCRIPTION
Being a sub-command of dh-exec(1), this program must not be ran directly, but through dh-exec, which automatically runs all available sub-commands if run bare; or explicitly with dh-exec --with=install. It is meant to be used for dh_install(1) files, and those alone. If it finds that its input is not such a file, it will do nothing, but echo back the contents. The purpose of the program is to extend dh_install(1)'s functionality, by allowing to specify a destination filename. This can be accomplished by a special syntax: the " => " mark between a source and a destination means that the source file should be installed with the specified destination name. For obvious reasons, the source must not be a wildcard, and the destination in this case must be a file, and not a directory. All other non-comment lines are left alone. RESTRICTIONS
Due to the way executable scripts are called from debhelper(1), there is no way to know what options were used for the original dh_install(1). This means, that the --sourcedir option of dh_install(1) will not work correctly when dh-exec-install is in use. IMPLEMENTATION
Internally, the renaming happens by creating a temporary directory under debian/tmp/, and copying (or moving, if the source was under debian/tmp/ to begin with) the file there, with the new name. This is done this way to allow dh_install(1) to do the real copying, and allow its options to continue working, even when renaming is involved. The temporary directory is put under debian/tmp so that it will be cleaned by dh_prep(1) when the clean target gets to run. Thus, no extra code is needed anywhere to clean up the renamed files. ENVIRONMENT
DH_EXEC_SCRIPTDIR Indicates which directory the command-specific scripts should be sought for. If not specified, scripts will be searched for in /usr/share/dh-exec/. FILES
