<html><body>Hi All<br /><br /><br />I suggested grep for this month's talk and enough interest has been shown to give it a go.<br /><br />It's used a lot with log files, configs, etc.<br /><br />But just recently, I've been working on some light manuscript manipulation, post scan - removing page numbers, adding new lines between paragraphs, rejoining line breaks, removing redundant white space, identifying and marking section headings and the like.<br /><br />I solved all these tasks by harnessing grep and sed and the almighty power of regexp.<br /><br />Along the way I found an exceptional article [1] by a guy (Peteris Krumins) who really knows how to research teach the concepts and who had found and used a excellent tutorial [2] by Bruce Barnett and a cheat sheet of one-liners [3] by Eric Pement, which Peteris' article examines in minute detail. Highly beneficial.<br /><br />Then out of the blue, my manager tossed a folder full of 6 months of web log files to be filtered and analyzed for a customer. "Just do one month. Don't spend too long on this!"<br /><br />Why would I need to? All 6 months in one swoop: easy and fast! I told him I'd used grep on Linux and he recalled using wingrep [4] long ago. <br /><br /><br />[1] Famous Sed One-Liners Explained by Peteris Krumins<br />http://www.catonmat.net/blog/sed-one-liners-explained-part-one/<br />http://www.catonmat.net/blog/sed-one-liners-explained-part-two/<br />[2] Sed - An Introduction and Tutorial by Bruce Barnett <br />http://www.grymoire.com/Unix/Sed.html<br />[3] Sed one-liners compiled by Eric Pement<br />http://www.catonmat.net/blog/wp-content/uploads/2008/09/sed1line.txt<br />[4] If you need grep on Windows, use the DOS find command or google for wingrep.<br /><br /><br />
