The LOG file in each folder is actually LOG.gz, which has been compressed with the open source, patent-free gzip program (http://www.gzip.org). The file, when expanded, produces a file named LOG with no extension. Once expanded, the LOG file is just a plain ASCII text file.
My first issue will be to discover if there is any utility in the J libraries that will expand this .gz file to is native form on a Windows machine. Ric Sherlock has shown us code that will find the LOG.gz file in each directory. I will be trying that out later tonight. ; (<empty'') -.~ (1 dir ,&'/LOG') each dirpath 'jsource' I will need to figure out what libraries to load in J to get the "empty",, "each" and "dir" verbs, so I can try this out. Once I figure out how to find and open the files, I will need string searching utilities to extract the text string I need. Can this be done in a non-iterating, array style in J, or will I need control loops to iterate through all the files?
