Re^4: Parse a tar.gz file without unzipping and uncompressing unzipping?
in thread Parse a tar.gz file without unzipping and uncompressing unzipping?
I've been using Cygwin for little things like this for years. Tar, gzip, zip, bzip2, etc., all work as expected from a normal Shell window (aka DOS window). If you have gzip or other compression installed, tar will support it natively, saving you some piping.
If you want to avoid Cygwin and/or get as much performance as possible, you can also get non-Cygwin, native ports of common linux/unix utilities here.
