I liked it. I'll stick with tar.gz though, always have used that and bzip2. Anyways, there is no discussion link at geekhaven, which is why cg= fuckup

Actually, CG = Pop Idol.

That article looks very interesting. I notice tarbell instead of tarball, but that's not a big deal...

i noticed that as well but just thought it was a thing I never heard of.

jimbob.tar and jimbob.tar.gz are different.

MB (who wrote the article) is going to change everything related to the tarbell mistake when he's got more time he's currently away from home and only has access to 28.8K

hmmm.... what is a tarball? a *.tar file? if that's the case, i was under the impression that *.tar files are just uncompressed archives.

http://www.faqs.org/faqs/compression-faq/p...section-25.html

tar is not a compression program. It just combines several files
into one, without compressing them.

if the above is the case, then how can a tarball have any compression stats? please define a tarball for me in these stats since this is a point of confusion as everyday verbage can have a tarball equalling *.tar, *.tar.Z, *.tar.gz, etc....

Sorry! I was under the impression that it was. I removed it and changed tar.gz to gzip, since that's the official name. I also included a note at the bottom that Tarball is not a compression algorithm.

The new version can be seen at the same location with a simple press of the reload (or refresh, depending on your browser! See, I don't discriminate

, though I will tell you that Opera is the best browser anywhere and you won't be able to visit my site if you don't use it)

Anyway, sorry for the little problems!

nothing to apologize for. everyone uses tarball for *.tar.gz and other compressed archives even though they really aren't the same thing. but it seemed because of this everyday usage, i felt that you just needed to clarify what you meant as a tarball, since a *.tar isn't a compressed archive and shouldn't have any compression stats.

so you can ]#tar -cvf * shitloadoffiles_become_one_that'snotzipped.tar
?

but adding the "tar -cvzf adds the compression?

yep. the "z" flag in the tar command tells it to use gzip. using the "j" flag instead of "z" tells tar to use bzip.
