Using variables in SSH

Shell Programming and Scripting
1

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.

Please let me know what modification is needed to resolve this.

Thanks in advance.

When using Variables in a path or generally next to other characters, use {} around it like ${VAR}.

Try

tar cvf /app/was6/AppServer/logs/prod_ebp_live_applogs_${DATE1}.tar `find . -name "*.log.${DATE1}" -mtime -1`

If tar still says it refuses to create an empty archive, try the same "find" on the command line directly and see if it brings any useful output back.
