I'm relatively new to perl and need some help. Basically, I have 10000 files containing a randomly generated set of strings that I need to check against a preset string. For each "data" input file, the program prints the number of times the preset string occurs to a "results" output file, with an individual line for each file that is checked. For example, the input/output might look like this: 
-file1-
stringa
stringa
stringb
stringc
stringc

-file2-
stringa
stringb
stringb
stringb
stringc

output:
File    A    B
1       2    1
2       1    3

I've written all the code to check the files, but right now I'm at a loss as to how to pipe each of the input files into the program. Is there a command for piping each file from a given directory into the program or something similar I could put at the beginning of the code? I apologize in advance if this ends up being a RTFM post, but I feel like I'm just missing something in the manuals.
