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. cgf >> On Wed, Jul 05, 2000 at 02:12:33AM +0200, Jonas Jensen wrote: >> >Well, silly me :-) >> > >> >Now, 2 more questions about that: >> > >> >-What the hell is the purpuse of that feature? >> >> Tar used to be commonly used with a tape device.
