Top Forums UNIX for Dummies Questions & Answers Copying files with the latest date Post 79734 by hadarot on Saturday 30th of July 2005 04:26:56 PM

If the modification times of the files don't necesarilly match the "dates" coded in the filenames, then you have to be a bit more creative. If this is part of a big project that you want automated, you should look into writing a perl script, which would read the directory filenames into an array, and then parse the filenames for substrings (those correspdng to "dates"), and order the array according to these substrings. In this way you can determine the filename corresponding to the most recent date.

Also, as more general advice, rather than making a copy of the most recent file, you should consider creating a symbolic link to it. E.g., in your example above, use:
ln -s bas100e1_jun05 bas100e1

But to get to the real issue: I don't know what you are trying to do with these different files. But if these file represent different versions/revisions of basically the same file, and you are using dates in the filenames to keep track of these revisions, then you are probably WAY better off looking into a version control system. Probably RCS is what you would want to use. Very simple and elegant...
