quick script question



Hi.. Need to ask you a simple script question,  I used the date command to get the yesterday web
log file using the following command echo ex`date -d yesterday +%y%m%d.log`  in Linux.  I want to
create a simple script to cat /home/IT/ex060530.log > kr.log using the following script but it is
not working.  May I know how do I put the output of echo ex`date -d yesterday +%y%m%d.log into cat
/home/IT/xxxx  > kr.log ?

[root w2 krweblog3]# echo ex`date -d yesterday +%y%m%d.log`
ex060530.log

[root w2 krweblog3]# vi krweblog.sh

#!/bin/sh
#
KRWEBLOG3= echo ex`date -d yesterday +%y%m%d.log`
cat /home/IT/$KRWEBLOG3 > kr.log
