If you just want to write to an output file, why not use dd?
I want to include several compressed disk images in a tar file, so that I can stream them at once across the local area network, without having to store compressed copies on disk before sending. dd is great for copying
one stream, in fact I've been using up to this point and intended to use it to feed the fifos, but it cannot multiplex several in a manner easy to seperate at their destination.
tar is being entirely too smart for it's own good, apparently. It could work if it'd just open the files. Is there any older, dumber archiver I can use?

Is there a performance advantage of one of these over the other? Obviously, it makes no sense to use normal TCP sockets or UDP sockets w/ the overhead they carry. But what about UNIX domain sockets vs FIFOs? I'd think they'd be very similar, in terms of performance and in terms of how they're... (2 Replies)

virt-tar-out
virt-tar-out(1) Virtualization Support virt-tar-out(1)
NAME
virt-tar-out - Pack a virtual machine disk image directory into a tarball.
SYNOPSIS
virt-tar-out -a disk.img /dir files.tar
virt-tar-out -d domain /dir files.tar
virt-tar-out -d domain /dir - | gzip --best > files.tar.gz
DESCRIPTION
"virt-tar-out" packs a virtual machine disk image directory into a tarball.
The first parameter is the absolute path of the virtual machine directory. The second parameter is the tar file to write. Use "-" to
write to standard output.
EXAMPLES
Download the home directories from a guest:
virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz
JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command. For anything more complex than a trivial
copy, you are probably better off using guestfish directly.
OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.
