Posted by in Software

Finding out when a directory was most recently modified should be relatively easy; just perform a dir or a ls -l and you should have it.

The most reliable way is, of course, to scan every file. To do that, I’ve got a simple program in two steps: Get the list of directories from a given path (not really related to the problem in…read more
