As acknowledged that's one of required special cases, but when I
expand an archive with two files on Unix I end up with two files
and not one as in the following on cygwin:-
tar -xvzf cygwin-test.tar.gz
w/
w/ls.exe
w/ls
[root@blade01]/tmp:
[root@blade01]/tmp: ls -l w
total 0
-rw-r--r--+ 1 root None 0 2011-01-04 20:42 ls
So not only did I loose a file I lost the windows one, not exactly
desired behavour.
What's even more confusing for the user is that its order dependent
so if the tar extracts w/ls followed by w/ls.exe instead of w/ls.exe
followed by w/ls you do get both files.
This always used to work just fine its only been broken in 1.7.
When I raised this when we first identified the problem we where
basically told that wasnt a valid use of cygwin so would not be
fixed, so I expect this directory problem which stems from the
same behavour will be the same as well :(
With something like cygwin there are always going to be querks and
gotyas but some of the recent "fixes" seem to taking a step backwards
breaking otherwise fine uses of this most valuable tool.
If anyone's interested in revisting this issue you'll find it under
the subject: "tar deletes .exe files on extraction" in the archives.
