Moreover, the slashes do not work on all distributions - e.g. on my laptop that still has Mdk 9.1 Pro I had to use single quotes, though I would have preferred to have used the slashes, which are used in perl regular expressions. Furthermore in perl you specifically set the ignore case as grep /.../i . Now finally add the warning I have seen: the switch/option on bash to ignore case (I believe is -i) does not work on all versions of bash! [Again, I really prefer the slash notation and when I am doing a match using php I use them; moreover, to protect my matching to ignore the case I use the syntax I noted above within the php functions.]<br /> <br /> I had some other problems that I would have preferred to have written the author about directly, however, so far I have received no advice on how to email him.<br /> <br /> These comments are <span style="font-weight: bold">NOT</span> meant to be overly critical - I want to see this and other series on the command line continued.

In the first section, 4th example... I may be wrong, but I don't think that the regex /^linux.*format$/ will match with either "linux Format" or "Linux users love Linux Format" by default... you need to have a flag set to ignore case.<br /> <br /> Which brings me to:<br /> <br /> 2. on the second page, where you mention the case-insensitive flag for grep, it is correctly printed as "-i" in the code example, but referred to as "-l" in the text.<br /> <br /> Hopefully these are just glitches that crept in during the typesetting/layout stage <img src="images/smiles/icon_redface.gif" alt="Embarassed" border="0" /> <br /> <br /> Otherwise a good article - I especially like the broken bookmarks example.<br /> <br /> <br /> Nigel. http://www.linuxformat.com/forums/viewtopic.php?p=940#940 Nigel Sun Apr 24, 2005 12:24 pm http://www.linuxformat.com/forums/viewtopic.php?p=940#940
