[1nickt]: ++YourMother (Grammar Vigilante of Bristol)
[Lady_Aleena]: Um, how does grep do multiline? print "$file:$_" if grep { /get_(array|hash| data)\(.+\)/ } $_; only returns the same 18 lines the command line grep does.
[Lady_Aleena]: my scratchpad has what I have so far.
[choroba]: what do you mean by multiline?
[Discipulus]: thanks 1nickt!
[choroba]: grep is a filter, it selects elements from a list based on a boolean condition
[moritz]: you need to read the file in one go to do a multiline regex match
[erix]: ha ha, I like the Vigilante
[Lady_Aleena]: Forget it. I'm getting angry with it.
[Lady_Aleena]: I'll just have to search for the files using the subs and open them up.
