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

rotatelogs

rotatelogs(8)						      System Manager's Manual						     rotatelogs(8)

NAME

       rotatelogs - rotate Apache logs without having to kill the server

SYNOPSIS

       rotatelogs logfile rotationtime [offset]

DESCRIPTION

       rotatelogs is a simple program for use in conjunction with Apache's piped logfile feature, which can be used like this:

       CustomLog "|bin/rotatelogs /var/logs/logfile 86400" common

       This  creates  the files /var/logs/logfile.nnnn where nnnn is the system time at which the log nominally starts (this time will always be a
       multiple of the rotation time, so you can synchronize cron scripts with it).  At the end of each rotation time (here after 24 hours) a  new
       log is started.

OPTIONS

       logfile
	      The  path plus basename of the logfile.  If logfile includes any Otherwise, the suffix .nnnnnnnnnn is automatically added and is the
	      time in seconds.	Both formats compute the start time from the beginning of the current period.

       rotationtime
	      The rotation time in seconds.

       offset The number of minutes offset from UTC.  If omitted, zero is assumed and UTC is used.  For example, to use local time in the zone UTC
	      -5 hours, specify a value of -300 for this argument.

PORTABILITY

       The  following logfile format string substitutions should be supported by all strftime(3) implementations, see the strftime(3) man page for
       library-specific extensions.

       %A     full weekday name (localized)

       %a     3-character weekday name (localized)

       %B     full month name (localized)

       %b     3-character month name (localized)

       %c     date and time (localized)

       %d     2-digit day of month

       %H     2-digit hour (24 hour clock)

       %I     2-digit hour (12 hour clock)

       %j     3-digit day of year

       %M     2-digit minute

       %m     2-digit month

       %p     am/pm of 12 hour clock (localized)

       %S     2-digit second

       %U     2-digit week of year (Sunday first day of week)

       %W     2-digit week of year (Monday first day of week)

       %w     1-digit weekday (Sunday first day of week)

       %X     time (localized)

       %x     date (localized)

       %Y     4-digit year

       %y     2-digit year

       %Z     time zone name

       %%     literal `%'
