Tarball?

What the hell is the point of having .tar.gz?  Is it double compression?  Does source code REALLY need that much?

tar is not compression.
gz is not archiving.

You're an idiot.

A tar only archives, it doesn't compress. gz and bz2 only compress streams, they have no notion of files or directory hierarchies.

HELLO IM LUNIS TARBALLS AND AS A SIGNIFICANT CONTRIBUTOR TO THE DEVELOPMENT OF LINUX KERNEL I APPROVE OF THIS THREAD

.tar isn't compression.

.tar isn't compression.
O RLY?

>>2 and >>3 are correct.  tar just globs a bunch of files into a single file.  It's original purpose in the UNIX of the 70's was to save space on reel-to-reel tapes.  Every time the tape would stop and then restart, a small space would be wasted.  If you'd write a bunch of files, there'd be a lot of space wasted.   So tar comes to the rescue, allowing one to write one big file to the tape and maximize the tape.

Read the XENIX programmers manual to see how the late 70's/early 80's UNIX worked (even though it's XENIX, an early 80's 286 implementation of UNIX, this text has a lot of manuals straight from the PDP versions of UNIX).  Everything is in a concise, terse format, in a pre-compressed format if you will.  Many of these vestiges live on in today's Linux, BSD, etc.  Compression came later, with separate utilites.

But yeah, it's not necessary to compress code that much.  But the .tar.gz thing is mostly a tradition, and a way to say "this is defintely for UNIX".  Better than those newfangled .bz2 punks, though.

Read the UNIX Programmer's Manual instead.

Informative. However:

1. Compression is valuable, now more than ever since the CPU is so much faster than long-term storage media. It's always profitable, even in databases, filesystems, etc.
2. I use .tgz instead of .tar.gz to piss people off.
3. bzip2 compresses better than gzip. However, it's slow as fuck.
4. 7-Zip offers a superior algorithm to both of them, and is faster than bzip2. It's also better to archive and compress in the same step, because you can tell what files do you have and perform certain operations on the file such as uncompressing just one of the files (if solid compression is disabled) more efficiently.

>It's also better to archive and compress in the same step...

That's true for the reasons you mentioned, but tarballs compress better because all the data is compressed as a single unit, so that common parts of different files can be encoded. I supposed it would be possible to develop a compression and archiving format that would compress all files against each other, but still keep the list of files separate so that they could be easily extracted singularly, but I don't know of such a format.

Depends. Just tar is perfectly fine for images, mp3s and the likes. If you're taring up your collection of Touhou music, adding generic compression like bzip2 or gzip to the process will only make it slow as fuck and it'll hardly help in the long run.

>>20
7-Zip also supports solid compression. It's just optional.
