The files I work with are actually logs that record information at set intervals down an oil well's borehole. So, depending on the depths of these logs, I have files that range in size from around 100kb to 50mb. My program only needs to read from a block of information at the top, and extract certain bits to a text file. Once it hits a specific delimiter, it closes the file and moves on to the next file. The file name is a 10-14 digit identification number plus an optional version number. When I was globbing the files, it was taking around 5 minutes to get started. With the readdir, it starts immediately.

in thread Things every perl programmer should know?
I am running perl version 5.6.0 on Win2k. Our machines here at work are managed by off-site personnel and have the registries and "Program Files" folders locked down so I can't upgrade the perl version or make any modifications to it. Any software has to be tested and packaged for company-wide distribution via intranet. It really sucks. So anyway, that's my situation. Here's the node where the readdir was suggested: File glob question. Let me know if you have any suggestions. Thanks!
