Perl: Loop through a file and substitute

Question

I simply wanna read in a logfile, do a search and replace, and then write out the changes to that same logfile. What's the best practice way of doing this in Perl?

Accepted Answer

I normally code up a one liner for this:

```
perl -i -pe 's/some/thing/' log.file
```
