The sad state of sysadmin in the age of containers

I usually get tar right on the first try. I only have to remember 2 variants (extract file and create file):

    tar xf ./foo #automagically works with bz2 and gz files
    tar cf /tmp/out.tar . #add z for compression

That second one will create a tarbomb[1], which isn't necessarily wrong and maybe it's what's right for your application, but for more general usage this is friendlier:

    tar cf <mydir.tar> <mydir>

And some of those switches are just for convenience, e.g.:

tar c . | gzip > /tmp/out.tar.gz

Oh cool. So that works? I've already memorized:

    tar -xvvzf foo.tar.gz
    tar -xvvjf bar.tar.bz2
    tar -xvvf  baz.tar

Thanks!
