Since this thread continues: the ``p´´ is usually on, so it can happen
that you find files on your disk that belong to some far away user id.
The ``f´´ option, among some others, is one that needs an accompanying
argument, i.e. the file into which to archive/from which to extract.
Long ago I have decided to first pass to tar the options without
arguments followed by those that need an argument. Among the 'pure'
options I sort them in a way that first comes the compressor type and
then the usual actions (c, x, vt). It's too good to introduce the
options with an argument with ``f´´ since it's so easy to recognize,
and too: you just add extras to the last of the usual options. So I
would use tar as in
tar zcf - ./local | ssh machine 'cd <target dir>; tar zxf -'
tar is very old, so the way to use it confuses many. Apple decided to
use GNU tar in Mac OS X. This tar accepts arguments too in a clear
tar --gzip --create --file - ./local | ssh machine 'cd <target dir>;
tar --gunzip --extract --file -'
And the man page is made well in explaining 'functions' and 'options'
-- a good concept!
If you're not confused, you're not paying attention
