As much as I’d like to be able to produce completely error free books, the reality of the computer publishing industry is that the pace at which books must be written and released makes this very difficult. And regretfully, my own books do have sporadic mistakes and typos scattered throughout them.
For the benefit of my readers, here is a current errata for Sams Teach Yourself Regular Expressions in 10 Minutes. Feel free to print this page for future reference.
And as always, if you come across errors that I do not know about, please let me know. I’ll make sure they are added to this list, and will try to have them corrected in future reprints.
