Rsh command

Question

In a script, I set the current date to a variable. I want to use that variable in my rsh command. The variable doesn't work. Here's what I do:
# Setting the current date
EXTENSION=`date "+%m%d%y"`
# Do copy on remote system using current date variable
rsh suntest 'cp /etc/passwd /etc/passwd.$EXTENSION'
When I run this, on the remote system it copies /etc/passwd to /etc/passwd. (passwd followed by period) so I can see it doesn't like $EXTENSION. Is it not possible to do this with 'rsh'?
Thank you!

Try creating a string variable with your command in it and then executing it. Here's sample code from my script:
exec_str="rsh ${SQR_SERVER} ${HOME}/bin/generate_rpt -i $in -o $out -h $host -u $username -p $passwd -a \"$args\" -d $print -q $queue -m \"$mvdir\" > /dev/null 2>&1; /usr/bin/echo \"\$?\""
remote_rc=`$exec_str`
