One thing I didn't make clear in my original post - it didn't seem important to confuse my real question which was the copy itself and not locating the files - but which likely changes how well some of these commands would work in my specific case was that the Builder directory actually has _many_ CSV files ut specifically I needed only the ones in the Correlation directories. Additionally, being that this is stock & futures trading data, generally at a given time I need the CSV files for a specific symbol, for instance in the original post: c2stable ~ # locate Correlation | grep Builder | grep csv /home/mark/Builder/TF/TF.D-17M-2009_06-2010_11/Correlation/TF.D-17M-2009_06-2010_11-V1.csv /home/mark/Builder/TF/TF.D-17M-2009_06-2010_11/Correlation/TF.D-17M-2009_06-2010_11-V2.csv /home/mark/Builder/TF/TF.D-17M-2009_06-2010_11/Correlation/TF.D-17M-2009_06-2010_11-V3.csv <SNIP> /home/mark/Builder/TF/TF.D-31M-2009_06-2010_11/Correlation/TF.D-31M-2009_06-2010_11-V4.csv /home/mark/Builder/TF/TF.D-31M-2009_06-2010_11/Correlation/TF.D-31M-2009_06-2010_11-V5.csv c2stable ~ # I knew I wanted the Correlation directory but it turned out I had other directories with that name on the system, so I added the grep Builder to get me into the right tree and CSV to find only the CSV files. However at that point I only had Russell futures data (TF.D) so I didn't have to go further. Now, however, as I bring in Dow futures (YM, YM.D) , S&P 500 futures (ES, ES.D), and NASDAQ futures (NQ, ND.D) I just an an extra grep in and I'm there in terms of finding the files I need for a certain test. Additionally I have test results for other date ranges that will show up soon, (2001-2005, or 2003-2011, etc. Additional greps are an easy way to just winnow it down to a point where I'm finding what I need to find. This thread has given me a lot of new commands to go look at. Thanks, Mark
