adding a line to a file

I want to add a line at the beginning and at the end of a file..

e.g.

echo "at the beginning.." > tmp_file &&
cat file >> tmp_file &&
echo "last line" >> tmp_file &&
mv tmp_file file

is there a nice way for doing that??

Thx

Code:
echo -e  "Before the data\n $(cat file)\nEnd of data"
