script help Undefined /illegal variable using cat

Hello group,

Still fairly new at the whole scripting thing so be gentle. I'm trying to write a simple script that archives my log files into a master log broken into weeks of the year.

My script runs fine up till the "cat" lines which I get a undefined or illegal variable name error. But using the same format earlier in the script it has no problem with the makedir or touch lines with the dates in them.

I have fiddled with it & had no luck, can someone eyeball this and tell me what I have done wrong? This is on a freenas system using a version of freebsd which is why I have the kooky copy lines instead of just echoing "" to the logs, which seemed to break syslog.

TIA
DP

Code:

#/bin/bash
#by DP run as ROOT!
#
#  make directory in format week number-year.month-year-logs
#
mkdir /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')
#
# touch new archived logs
touch /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')/sshd.log
touch /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')/system.log
#
#stop syslogd deamon
/etc/rc.d/syslogd stop
#
#copy sshd & system log to monthly directory
cat /var/log/sshd.log >> /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')/sshd.log
cat /var/log/system.log >> /var/log/archives/'week-'$(date +%U'.'%B'-20'%y'-logs')/system.log
#
#copy clean sshd & system log file to clear logs
cp /var/log/clean/sshd.clean.log /var/log/sshd.log
cp /var/log/clean/system.clean.log /var/log/system.log
#
#
#restart syslogd
/etc/rc.d/syslogd start
#
# log results
logger SYSTEM "Daily rotation of SSH & System logs was successful stored in /var/log/week-"$(date +%U'.'%B'-20'%y'-logs')
#
# EOF

bf_tar

BF_TAR(1)						    Bogofilter Reference Manual 						 BF_TAR(1)

NAME

       bf_tar - shell script to write a tar file of a bogofilter directory to stdout

SYNOPSIS

       bf_tar [-r] [-R] bogofilter_directory

DESCRIPTION

       bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see
       EXAMPLES below).

OPTIONS

       The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log
       files.

       The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive
       is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files.

EXIT STATUS

       The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.

EXAMPLES

       o   bf_tar ~/.bogofilter > outfile.tar

	   Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar.

       o   bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz

	   Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz.

       o   bf_tar `pwd`/mydirectory > outfile.tar

	   Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path.

NOTES

       This script is meant for use with Berkeley DB based bogofilter versions.

       This script requires a SUSv2 compliant pax utility.

       This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so
       that /usr/xpg4/bin/sh can be used.
