Re: Re: Grep Pattern Match

Thank you... Your nudge got me in the right direction. here is the code I am using: @files = grep {/^nc$digyear$digmon.*\.log$/} @files; Works like a charm :)

+\n"; } else { print "Thats a dog\n"; } print "\n";'

This is just a slight optimization - read up on qr// in perlop to get the full scoop. `$match = qr/^nc$digyear$digmon.*\.log$/; @files = grep m/$match/, @files;` [download] Fun Fun Fun in the Fluffy Chair	[reply] [d/l]

Slightly dangerous if the application calls for using the regex in a loop where one of the variables (eg. $month) changes, as unless the qr// is also inside the loop (in which case the optimisation benefits are lost), as the changing value of the variable won't be recognised. Examine what is said, not who speaks.	[reply]

Are you sure? I thought that the regex was being recompiled on each iteration to that block which is why I posted that. Fun Fun Fun in the Fluffy Chair	[reply]

I am not really going for optimisation (yet)... just want a script that will parse my log files that will search for attempted DOS's and stuff and then take those IP's and add them to our deny list. That is all I am writing this for. ----------------------- Billy S.
