How to read and grep compressed & rotated log files

Your typical server log directory looks something like this: ```bash access.log access.log.1 access.log.1.gz access.log.2.gz ``` Now what if you want to extract data from day x to day y? You could use gzip and grep to uncompress the files, but there's a better way: the z commands. All you have to do is: ```bash zgrep "2010" /var/log/apache2/access.log* ``` More info on the subject can be found here:
