[Ilugc] Sed should affect the input file

What is the option should I need to set, so that the replacement string
should affect the Input file
Example:
sed 's/<old>/<new>/g' input_file
Then If I open input_file the file the effect should take place in the
input file.
Is it possible to do that?
We can do with PERL directly as,
perl -pi -e 's<old>/<new>/g' input_file
so that pattern matching changes will be updated in the same input_file.
To accomplish with sed then,
sed 's/<old>/<new>/g' input_file > outputfile; mv outputfile input_file
HTH.
Thanks,
