Of course, we're talking about Cygwin, which uses GNU tar, and GNU
tar will happily use the option that I mentioned.
If you want to do more typing, this mechanism works great, too.
Or, if you want to vary this slightly and confuse the issue a little more,
you can also do:
zcat filename.tar.gz | tar xvf -
gzip -c -d filename.tar.gz | tar xvf -
/bin/gunzip -c < ./filename.tar.gz | /bin/tar -x -v -f - -C .
If you are looking to do the maximum amount of typing then the last option
is obviously the best.
