searching logs from .bz2 and alternate to tail


Hi

Just a quick question.
How to search through the log file which is in .bz2 format. I know to use zgrep to search the pattern through .gz but couldn't find anything for .bz2? I don't want to uncompress it first and then search through.


Second question
Is there any alternate to tail or cat which starts parsing the file from the end towards the start, rather starting from the beginning to the end?

Regards
Fani

Some distros have tac (cat reverse).
