On NCR Tower unix, release 20100, the unpack we have unpacks linked packed files. I discovered this because I wanted to unpack, then compress the man files, some of which are linked. Compress isn't this stupid - it doesn't unpack these files. Beware - this is going to cause me some headaches. Greg Disclaimer - Thomas Cooks Iron, My Opinions Greg Calkin Thomas Cook N.Z.

What do you expect from System V? Geez. System V only has hard links. If you modify a file, the link is destroyed. (I'm probably explaining this badly). When you unpack a file, it becomes a seperate file. Someone out there probably has written a script or program to handle this, but it is not a System V bug -- it's a System V "feature". aem a.e.mossberg - aem@mthvax.cs.miami.edu/aem@umiami.BITNET - Pahayokee Bioregion The life of money-making is one undertaken under compulsion, and wealth is evidently not the good we are seeking, for it is merely useful for the sake of something else. - Aristotle

If you modify a file, the link is destroyed. >(I'm probably explaining this badly). Actually, NCR has implemented symbolic links for System V. So far as I know, these aren't used by any of the "standard" software supplied by NCR. We use them for development, but compared to Berkeley symbolic links, they are not complete (particularly with respect to linking directories).
