Sometimes it would be really useful if you could, in real time, join all the log files (/var/log/* in my distro.) and do a tail -f on them except the ones you exclude from a directory (e.g. .bz2 files).
Has anyone tackled this idea and come up with a solution? I would really like to do this and it's especially useful on new hardware when something weird is going wrong and you are not yet sure where.
