Full Discussion: Hpux find tar gzip
Operating Systems HP-UX Hpux find tar gzip Post 302979032 by rbatte1 on Monday 8th of August 2016 06:00:43 AM

These options will struggle with too many filenames because xargs will produce multiple commands from the list. The command xargs (as I understand it) will take the input list and try to make a single command line from the options given using the input as described or as the final part of the line by default. If the line is going to exceed the maximum command length, then xargs will loop on the command with the remaining input.

With a tar this could be disastrous because the potential multiple tar commands would not be able to be disentangled if you needed to read it back.

If this was AIX, I would recommend writing the names of the required items into a temporary file and passing that with the -L flag, but I'm not sure that HP-UX or anything else supports that. Solaris might use -I (capital i) instead. You would have to read the manual page and look for a flag to accept a list or input file.


Could you consider cpio or other tools instead?

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.

SEE ALSO

       guestfish(1), virt-cat(1), virt-copy-in(1), virt-copy-out(1), virt-edit(1), virt-tar-in(1), http://libguestfs.org/.
