Re: TAR command

Hi,

Your tar version does not support the uncompress/unzip function.

Less crude would be something like:

tar cvf - /home/oracle/scripts | \
gzip > /backup/aaa/cb.tar.gz

which, I believe, is essentially what GNU
"tar" does for "-z". Works with bzip2, too,
or any other filter-like compression program,
whether your "tar" program knows about it or
not.

Sometimes it pays to know how to do things
the old-fashioned way (before "-z" existed).

Re: TAR command

sure you should know how it works, and what the alternatives are, just in case.

but, common, we admins are lazy bastards, if i can replace a 20 char command with a single letter, i'm happy ;)

I'm so lazy (or stupid) that I can barely
remember one way to do anything, so I try to
remember the one way which will work
anywhere.
