It seems that modifying a file makes the last-modified time on the file's directory change as well. This is a little bit odd, since the directory doesn't have to change unless the file's INODE changes, and I don't think that's happening. I may not be testing this properly... Please, no arguments about whether this is a good thing or a bad thing. What I want to know is: is it standard behaviour? Can I depend on this occuring on all UNIX systems, all BSD systems, some BSD systems, or what? I'm writing a Makefile to handle the rebuilding of my pathalias database. Rather than dynamically rebuild the Makefile to contain an explicit list of dependencies (the map files), I thought I'd just have the database depend on the directory containing the map files. It seems to work, here. My system is more or less 4.2 BSD (it's a Symmetric 375). Please reply by mail if this is an old and often-rehashed topic.
