Can someone tell me how to untar, and un-zip a file with
this extension, using gnu-win32's tools? Thanks.

gzip -d *.gz, then tar -xvf filename.tar. Get the book Unix for Dummies.

Try

    tar xzf file.tar.gz

If you are not using GNU tar then you may have to unzip the file
before untarring

    gunzip -c file.tar.gz | tar xf -

Last time I checked (version b17.1), this did not work,
because pipes were opened in text mode, not binary mode.
Instead I had to use

     gunzip file.tar.gz
     tar xf - file.tar

Has this changed since b17.1?

Or, just get WinZip 6.2.  It'll ungzip it, and untar it.  But, command
line is more fun!

I don't think so.  But using the 'z' option to gnutar works as it
always has:

	tar xzf file.tar.gz

There has been at least one copy of bash floating around which was
compiled with O_BINARY as the default for open.  That would allow the pipe
version above to work.

A warning - WinZip (as of 6.3 build 4.1) doesn't notice some corruptions in
gzipped files - I've reported this to Nico Mak and it will hopefully be
fixed before 6.3 is released.

Yes, but the 'z' option to tar is not portable, so I can't use that. :-(

I had thought that the issue wasn't the use of gzip/gunzip itself, but the
-z flag to tar, which causes gzip/gunzip to be invoked if using gnu tar, but
may do other things on other versions of tar.  I don't think that anybody
has questioned gzipping archives as being non-portable, just how to handle
them.

Re: .tar.gz

[Chris Faylor]

I don't see how anyone could ever argue that gzip is "non-portable".
In fact that isn't what this thread is about.  Of course it is "portable";
it's got something called a "configure" script which goes to great pains to
ensure that it will run on as many platforms as possible.

The point that was being made is that 'gzip' is not distributed, by
default, with many computer systems.  Most UNIX distributions do have a
'compress' program, however.  That doesn't mean that compress is more
"portable" but it does mean that it is more widely available.

The original poster was not saying that the compress code was more
"portable".  He was pointing out that if you expect to find 'gzip' on
every UNIX platform you'll be disappointed.

Hail Jason!

Very good point.  I've felt that this debate about gzip being
non-portable was bogus as well.  Every UNIX and PC I've been
using has had a cross-platform compile of gzip.  Never had
a problem.

gzip/gunzip are a helluva lot more portable than compress/uncompress;
the code is universally available, and unencumbered by the Unisys patent
on LZW compression. The requirement for a patent license to ship
compress has driven us away from providing it; we use gzip/gunzip.

(It's worth noting that the FSF holds that the Unisys patent applies to
LZW compression, not decompression; thus, gzip won't use LZW
compression, but gunzip can uncompress files compressed with LZW.)

Good point!

Also, for the uninitiated, the above example is wrong anyway.  It really
should be:

	gunzip file.tar.gz
	tar xf file.tar

But, really, just use "tar xzf file.tar.gz".

We distribute our software only in .tar.gz form.  In order to execute
it, the user must have unpacked it first, and to unpack it, they must
have g*zip (and tar).  But they might not have GNU tar.

Also, if they happen to not have gzip, the error message "gzip: command
not found" will be pretty clear.  Whereas if we invoke tar with the 'z'
option, it might just do the wrong thing.  E.g. on the system I'm posting
this from:

But g*zip is not portable, either, only *compress is "standard" on unix.
You can just as well install gtar, under that name, too (or link on Linux).
