Two things are infinite: the universe and human stupidity; and I'm not sure about the universe. |

My Amazon Wish List
I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my 
Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)

Nice article! I was wondering what the default values are for $HISTIGNORE. This is not defined by default on my system, (Debain Sid), but does ignore a space by default. I was wondering if there are any other characters ignored by default without having to dig through the source. Can't find any documentation.
Thanks!
Rick

It's not defined (empty) by default! That's why it ignored a space.
