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.
Thanks,
