Let’s say you’ve got a string like:
$ string="abc.Cat.def.1.zip.hij.Cut.klm.1.zip.Cat.no.2.zippqrs"
Out of this string, you want to pick out Cat*zip (Cat.def.1.zip and Cat.no.2.zip), “.*” works but is greedy so this grabs too much:
$ echo $string | grep -Eo "Cat.*zip" Cat.def.1.zip.hij.Cut.klm.1.zip.Cat.no.2.zip
This does what we want:
$ echo $string | grep -Eo "Ca[t][^t]*.zip" Cat.def.1.zip Cat.no.2.zip
Previously, I had setup an Ubuntu Karmic box to install Boxee from the apt.boxee.tv APT repository. Since this repository appears to be unmaintained, I’m now reverting back to manual Boxee installs until an updated repository becomes available.
I haven’t been getting any SPAM lately, so I thought I’d turn on catch-all to see what happens. Accepting mail for invalid recepients (e.g. anything @mydomain) caused about twice as much SPAM to be attempted, but still nothing got through to my Inbox:

As you can see, Postfix got most of it, then SpamAssasin got the rest. I heart Postfix and SpamAssassin.
