SED Insert & Append lines in a script

[gxh1000]

I have a file that I am manipulating in a Unix script. I want to use a sed command to insert text before the 1st line:

DATE $TDYSDATE //where $TDYSDATE is a variable set in
the script.

And I want to append text after the last line:

ENDOFFILE

This is what I've tried and it doesn't work:

#!/bin/ksh
cat test_file | sed '1i\DATE $TDYSDATE' \
'$a\ENDOFFILE' > new_file

I've tried numerous variations of this and I keep getting the same error - "Extra Text At End Of Command"

Please help.

does

sed '1iDATE $TDYSDATE' test_file | sed '$a\ENDOFFILE' > new_file

work?

You may try something like this:
(echo "DATE $TDYSDATE";cat test_file;echo "ENDOFFILE")>new_file
But if you insist on sed:
sed "1i\
DATE $TDYSDATE
"';$a\
ENDOFFILE
' test_file > new_file

Hope This Helps, PH.

None of the sed proposals work, but the echo suggestion does. So, echo it is. PHV, thanks for your help.
