kvale,
While this is a perfectly good solution, it may be an issue if the file in question is very large. In that case, instead of slurping the whole thing into memory it might be better to use a perl implementation of tac. If you need to manipulate the lines at all in addition to reversing them, you could always have a look at File::ReadBackwards

For any other conversions of sed, there is always the s2p utility that ships with the core.
