sed to read and write to very same file

This is likely to be a dumb one.

How can I use sed to substitute string occurances having it read from an input file and write to this very same file ?

I have a file with lots of occurances of '2006', I want to change it to '2007', but I'd like these changes to be saved on the input file.

How do I achieve this ?


Thanks in advance,
Abrahao, Brazil.
