Writing is a bit harder, though, if you want to be able to do a 'tar r', since (quite logically) tar r does not make sense on standard output. 4.3 tar handles remote drives, so I fished it out and compiled it and friends on a Sun, but alas, no luck. 'tar r' works fine locally on the 4.3 BSD Vax, but not from the Sun, where the subsequent archives don't show up in a tar t. Looked in the source, and the rmt stuff looks perfectly orthodox. We only have one machine running 4.3, so I could not try from a remote one... Also, I often find myself doing a big find -prune ... followed by a session of purification with a text editor, in order to get a reasonable list of files to put on tape. In the absence of 'tar r', using xargs to handle a huge list of arguments is out of the question, and the only tar I know that can read standard input for its list of files is John Gilmore's etar, but that one does not support on the fly change of directories, and does not follow symbolic links. Am I missing something? Ah well. I cross-posted to comp.unix.questions and redirected follow-ups there.

I have patches to make 'tar' do remote drive stuff.
