Hello everyone,

I have a question on a change I need to apply to the following code:

perl -sple"BEGIN{open BIG};($undef,$l)=split;read(BIG,$_,$l)" -- -BIG=
+bigfile.dat index.dat >outfile.dat

[download]
As you can see I have 2 files one is data the other is an index file with offset and length for each of the record in the data file. I would like to modify this command in such a way that I can also pass let's say three string vars (could they also be regexp's?), and at the completion of the modified command it will return 3 counts (one per passed var) each count will tell me how many of the records contained var1 or var2 or var3.

I hope one of you wise perl monks can help me out.

Thanks!
