Hello,

I want to extract a number of files from a tar.gz archive.
I want to extract them all into a single directory, regardless
of their path in the archive.  I haven't found a switch in the
gnu manual for this.  Is it possible?  I realize I can extract
them into the directories as per their full path, then move
them to a common directory.  But if gnu can extract them into
the common directory, I use that feature of course.

Thanks.

But you can flatten the result with (untested):

tar -C output -zxf archive.tar.gz
cd output
find . -type f -exec mv -i {} . \;
find * -type d -prune -exec rm -rf {} \;

$ zcat archive.tar.gz | pax                 
./
./dir/
./dir/subdir/
./dir/subdir/b
./dir/subdir/a
./dir/a

$ zcat archive.tar.gz | pax -r  -s ',.*/,,p'
./ >> 
./dir/ >> 
./dir/subdir/ >> 
./dir/subdir/b >> b
./dir/subdir/a >> a
./dir/a >> a

$ ls
a       b

Thank you, Pascal.  I was thinking about "find" for the case
where a suitable switch is not available for tar.

Thank you, Sven.  I'll keep that in mind for when
pax is available.  I know from the cygwin mailing
list that this is possible, even through it doesn't
come with cygwin itself.
