Prepend content of a file to another file

How can i prepend the content of a file to another file? I tried:
sed '1r textfile' myfile
but it inserted the text AFTER the first line? What would be a good method?

I can easily append lines to a file using the ">>" operator, is the something similar in bash to prepend lines?

Kind regards

Chris

From: Sed - An Introduction and Tutorial
You can insert a new line before the pattern with the "i" command:

sed '
/WORD/ i\
Add this line before every line with WORD
' file

To prepend f2 with the contents of f1 you can simply do something like:

cat f1 f2 > f2.tmp && mv f2.tmp f2
