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?

SVNWRAP(1) General Commands Manual SVNWRAP(1)NAME
svnwrap - Umask wrapper for subversion client commands
SYNOPSIS
svnwrap {program} [args...]
DESCRIPTION
svnwrap is a simple shell script to work around permission problems when sharing Subversion repositories between multiple local users.
svnwrap can be used either by specifying a particular subversion client command on the command line, or by invoking it by the same name as
the desired client command, via a symlink.
svnwrap sets the umask to 002, then launches the appropriate subversion client command. For complicated reasons, this is needed when using
the clients with BDB-format repositories, but not for FSFS-format ones.
EXAMPLES
To create a new BDB-format shared repository (note that FSFS-format shared repositories should also be created this way):
svnwrap svnadmin create --fs-type=bdb /path/to/repo
chgrp -R shared_group /path/to/repo
The following line in /etc/inetd.conf can be used to serve svn:// URLs:
svn stream tcp nowait my_svn_user /usr/bin/svnwrap svnserve svnserve -i -r /srv/svn
The following commands enable use of svnwrap for local file:/// and remote svn+ssh:// URLs:
ln -s /usr/bin/svnwrap /usr/local/bin/svn
ln -s /usr/bin/svnwrap /usr/local/bin/svnserve
svn is used for local file:/// URLs, and svnserve is invoked by remote users of svn+ssh:// URLs.
BUGS
If you symlink the svn binary to svnwrap, as shown in one of the examples, all local users' working copies will also use the new umask. Be
sure to warn your users about this, as security-related surprises are rarely pleasant.
