concatenate compressed and uncompressed logs

I use zgrep because it also parses non gzip files.

With ls -tr, we parse logs in time order.

Greping the empty string just concatenates all logs, but you can also grep an IP, an URL...

Alternatives

There is 1 alternative - vote for the best!

Terminal - Alternatives
zcat -f $(ls -tr access.log*)

with zcat force option it's even simpler.

find /var/log/apache2 -name 'access.log*gz' -exec zcat {} \; -or -name 'access.log*' -exec cat {} \;

This command allows you to stream your log files, including gziped files, into one stream which can be piped to awk or some other command for analysis.

Note: if your version of 'find' supports it, use:

find /var/log/apache2 -name 'access.log*gz' -exec zcat {} + -or -name 'access.log*' -exec cat {} +
