Single line backups with find or cat and xargs, etc
Hi, I'm new here and this is my first post. I used command line Unix at work for 3 years... about 10 years ago! Now I can't figure out nor hunt down examples of how to do the following:
Say I built a list of file to backup like this:
Code:
find ~ -name "*.pdf" -print >> MYPDF.txt

So I am using find with a redirection operator to a plain text file. Now I want to say... cat that file and pipe it to xargs using the cp command to copy them all to a single directory so I can tar them into a tar ball... but I am screwing it up!!
Code:
mkdir NEW_PDF_DIR
cat MYPDF.txt | xargs cp NEW_PDF_DIR

then I want to do something like:
Code:
tar  -cfv PDF_ARC ./NEW_PDF_DIR

Several things going on here... trying to find to build a list to use to create a tar archive... more or less. And hey, if there is an easier/smarter way to do it, Thank you all! (I figure it can be done in 1 line at the shell prompt... but hey I am re-acquiring skills here!)

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/>.
