I'm not sure what letters would go on the end of "porn" to make a clothing item, but I'll bet it exists. Or someone misspelt "pony", or... well, you get the idea. No matter what, you really don't want your site to appear in search results for those terms.

Is this what we will call it when the NSA starts blackmailing politicians with their internet histories?

It means rule of the whores and is a certain period in the catholic church.

> Saeculum obscurum (Latin: the Dark Age) is a name given to a period in the history of the Papacy during the first half of the 10th century, beginning with the installation of Pope Sergius III in 904 and lasting for sixty years until the death of Pope John XII in 964. During this period, the Popes were influenced strongly by a powerful and corrupt aristocratic family, the Theophylacti, and their relatives.

Why are you catting a single file into grep?

Muscle memory. I find myself doing this all the time too, it is just a universal way of filtering things down, so I don't worry about it too much. Like when using lsof, sure you can use filters via lsof itself, but sometimes you just use "lsof |grep" because it is easier than looking up the correct option. The performance to muscle memory tradeoff is worth it.

I think GP may be referring to the "unnecessary use of cat"

The correct way:

grep "^porn" /usr/share/dict/words

Nothing incorrect about using cat. It makes almost zero practical difference except saving a couple keystrokes. There are some scenarios where it actually matters, but this isn't one of them.
