That is a very big and complicated command. I would try and unwrap that a little, not jam everything on one line.
Also, you can't jam multiple lines of text in a variable and expect them to work right. Quoting them is a bit of a hassle. Save it in a file instead -- that makes it easy to use in a loop or transfer into anything else.
How do I evaluate the result of a command assigned to a variable??
Example:
var1=`cmd`
rc=$?
rc will be the result of the assignment rather than cmd since it executes after. How do I evaluate the result of the command itself?

LEARN ABOUT DEBIAN
dh-exec-install
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/.
