Yup. Also you can do this on the command line using things like perl -nle (make an input loop) or perl -pi -e ("in-place" editting) as described in the perlrun manpage.

Since my paranoia turns on when I use -pi I often turn off paranoia (a biological process) and do something like
cat bigfile|perl -nle 's/escaped_old_ip/new_ip/g; print;' > newbigfile

You can also process files using the tie command, there are many modules which use it (Tie::). Good luck!
