Please tell me what is wrong in the following shell script.

#!/bin/sh
DATE1=`date -d "yesterday" +"%Y-%m-%d"`
ssh ftwplapp01 << EOF
echo "Date is :" $DATE1 > /tmp/testfile
cd /app/was6/AppServer/logs/prod_ebp_live/ebp
tar cvf /app/was6/AppServer/logs/prod_ebp_live_applogs_$DATE1.tar `find . -name "*.log."$DATE1 -mtime -1`
EOF


DATE1 is not resolving under ssh. In other words, /tmp/testfile is not getting the value of $DATE1.

I'm getting following output:

was6@vmulport04:/app/weblogs/scripts> ./applogs_ftp.sh
Pseudo-terminal will not be allocated because stdin is not a terminal.
