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!!
You you don't say what OS you are using some GNU options can make this task easier. If cp implementations the cp -t DIRECTORY SOURCE ... method, then this makes xargs much easier to work with:
Also GNU xargs allows a --no-run-if-empty which to avoids invoking cp if no files exist to be copied.
If NEW_PDF_DIR is under your home directory, you will want to prune it to avoid trying to backup the backup files!

lorder
lorder(1) General Commands Manual lorder(1)NAME
lorder - Finds the best order for member files in an object library
SYNOPSIS
lorder file...
DESCRIPTION
The lorder command is essentially obsolete. Use the following command in its place: % ar -ts file.a
The lorder command reads one or more object or library archive files, looks for external references, and writes a list of paired filenames
to standard output. The first of each pair of files contains references to identifiers that are defined in the second file. You can send
this list to the tsort command to find an ordering of a library member file suitable for 1-pass access by ld.
If object files do not end with lorder overlooks them and attributes their global symbols and references to some other file.
EXAMPLES
To create a subroutine library, enter: lorder charin.o scanfld.o scan.o scanln.o | tsort | xargs ar qv libsubs.a
(Enter this command entirely on one line, not on two lines as shown above.)
This creates a subroutine library named libsubs.a that contains charin.o, scanfld.o, scan.o, and scanln.o. The ordering of the object mod-
ules in the library is important. The lorder and tsort commands together add the subroutines to the library in the proper order.
Suppose that scan.o calls entry points in scanfld.o and scanln.o. scanfld.o also calls entry points in charin.o. First, the lorder command
creates a list of pairs that shows these dependencies: charin.o charin.o scanfld.o scanfld.o scan.o scan.o scanln.o scanln.o scanfld.o
charin.o scanln.o charin.o scan.o scanfld.o
This list is piped to the tsort command, which converts the list into the ordering that is needed:
scan.o scanfld.o scanln.o charin.o
Note that each module precedes the module it calls. charin.o, which does not call another module, is last. The second list is then piped
to xargs, which constructs and runs the following ar command: ar qv libsubs.a scan.o scanfld.o scanln.o charin.o
This ar command creates the properly ordered library.
