<html><body>Hi All, this is aimed at those who were at the August moot.<br /><br /><br />I've updated my analysis file quite a bit and written up the instructions with notes so you can step through it again whenever you decide.<br /><br />I've put it up on the East Grinstead site for download. All the same tutorial and cheat sheet links are there at the bottom of the page with notes on how I prepared the practice file, and I've retested the three commands we focused on.<br /><br />The text I chose is particularly challenging so provides for more interesting experimentation. That text, in 1928, would have been typed up by hand (more than 1000 pages) and then the printing plates for each of the 16 volumes within it would have been hand set. This would partly explain why the paragraph indents vary from section to section, ranging from 2 to 6 characters. There are also a great many bordered quotes interspersed, which end up as spaced out character strings floating around haphazardly in the plain text version.<br /><br />Among other manipulations remaining to be done are the elimination of extra white space within paragraphs, and here again, the varying indents limit the accuracy of any one expression - unless you take the text one section at a time. There are options which let you define line numbers but that will have to be left as a further challenge. We didn't even touch on stored scripts.<br /><br />Anyway, here's the link: http://www.eglug.org.uk/bash_and_regexp_example_analysis.html<br /><br />I enjoyed the exercise and I still refer back to the analysis when crafting additional expressions. Writing it all up prior to the moot was painstaking as was revisiting it afterwards, but well worth it as it cemented my understanding. Running (successful) sed commands one after the other and seeing the results is like magic :-)<br /><br />Let me know if you give it a go, and please post your feedback.<br /><br /><br /><br />
