Help in regular expression Posted by shafa.fahad (FahaD), 7 November 2006 Hi,I am relatively new to perl and hence the regular expressions as well.... Please help me understanding this re syntax, To be precise i need to know what and all pattern the below expression matches to if ($string =~ /^(ORA-[0-9]+):.*/ || $string =~ /.*[ ]+(ORA-[0-9]+):.*/ || $string =~ /^(Corrupt block)/) Thanks in advance Fahad Posted by admin (Graham Ellis), 7 November 2006 Ah - I think you need our regular expression course ![]() Your example looks for a string which ... starts with ORA, followed by some digits and a colon OR contains the same thing after a space OR starts with "Corrupt block". If you need a full explanation of how, where, why, etc ... then I don't think that the forum's a very good place for me to tell you - I would be re-writing a whole book. There are complete books on regular expressions (see our library) or, as I said earlier, we do a one day course. This page is a thread posted to the opentalk forum
