OK, I have figured out how to get a list of each of the paths to each of the log.gz files in my directory tree.
lp =: (> 1 }. 1 dirpath 'c:\test4') ,"1 '/log.gz' lp c:\test4\00-00-36-vx1prn123-7b42060a_00000d48_4eab4224_0060_0000/log.gz c:\test4\00-02-36-vx1prn123-7b42060a_00000d48_4eab429c_0061_0000/log.gz c:\test4\00-02-45-vx1prn123-7b42060a_00000d48_4eab42a5_0062_0000/log.gz c:\test4\00-05-24-vx1prn123-7b42060a_00000d48_4eab4344_0063_0000/log.gz c:\test4\00-08-24-vx1prn123-7b42060a_00000d48_4eab43f8_0064_0000/log.gz c:\test4\00-09-39-vx1prn123-7b42060a_00000d48_4eab4443_0065_0000/log.gz c:\test4\00-36-16-vx1prn123-7b42060a_00001cd4_4eab4a7f_0001_0000/log.gz c:\test4\00-36-31-vx1prn123-7b42060a_00001cd4_4eab4a8f_0002_0002/log.gz c:\test4\00-39-28-vx1prn123-7b42060a_00001cd4_4eab4b40_0003_0000/log.gz c:\test4\00-40-53-vx1prn123-7b42060a_00001cd4_4eab4b95_0004_0002/log.gz I know this is a bit of a brute force approach, but it ets the job done. Since I know that there is one log.gz file in each subdirectory, I can append the '/log.gz' string on the end of each directory path, to complete the full path. I assume that there is some 'findfiles' utility that can do the same job more elegantly without jamming strings together, but I haven't found it as yet. Now that I have the list of file paths, I need to open each file and operate on it. I have predefined two path nouns: zipth "c:\Gzip\gzip.exe -d -c " filepth c:\test3\log.gz So, I can pull out a file and unzip it, given the file path: $ shell zipth, filepth 237567 But that is just one log.gz file unzipped into a text array. Now I need to iterate through all of the list of log file paths I extracted above, and create an array of boxed text strings, one boxed string per expanded log.gz file. "lp" contains the list of files, one path per row. $ shell zipth, lp |rank error: uucp | r=.CreateProcessF 0;( uucp y);0;0;inh;f;0;0;si;pi That won't work. $ shell zipth, each lp |length error | $shell zipth ,each lp Nope. How can you make the shell command iterate through the list of files, to unzip each log.gz file and put each unzipped text string in a new boxed array?
