The way i understand the use of tar + gzip is that
tar is normally used to consolidate a grouping of files into a single file, then
gzip is used to compress that file.
I recently learned that
tar can ALSO compress.
Because I do not fully understand how compression works @ it's core, I have (possibly ridiculous) concerns that sending a pre-compressed .tar to gzip might prevent gzip from compressing as well as it's potential would allow and things of that nature.
My question is essentially: What combination of args/compression methods should i use to create the absolute smallest tar.gz, and what does the command line statement look like for that?
