What OS (including version) are you using? (If you don't know, show us the output from the command: uname -a).

What have you tried to solve this problem?

Are the target directories you mentioned to be created in the directory that contains these files or in a different directory?

Are the output files from running the awk commands to be placed in the directory that originally contained the files, in the directory where the files being processed by each awk command have been moved, or in some other directory?

Do the directories to which the files are to be moved already exist? If so, are other files (that are not to be processed by the awk command for the files to be moved to that directory) in those directories?

What is the maximum number of files that could be moved into one of these target directories? (Or, more importantly, will invoking awk with the awk script and the absolute pathname of all of the moved files run into ARG_MAX limits? If there are enough files that that could be an issue, will the output from the commands:
Code:
cat FILE-2014-10-30-*| awk 'your awk script' > Codes-2014-10-30.txt

and:
Code:
awk 'your awk script' FILE-2014-10-30-* > Codes-2014-10-30.txt

be different?)

dh_movefiles

DH_MOVEFILES(1) 						     Debhelper							   DH_MOVEFILES(1)

NAME

       dh_movefiles - move files out of debian/tmp into subpackages

SYNOPSIS

       dh_movefiles [debhelperoptions] [--sourcedir=dir] [-Xitem] [file...]

DESCRIPTION

       dh_movefiles is a debhelper program that is responsible for moving files out of debian/tmp or some other directory and into other package
       build directories. This may be useful if your package has a Makefile that installs everything into debian/tmp, and you need to break that
       up into subpackages.

       Note: dh_install is a much better program, and you are recommended to use it instead of dh_movefiles.

FILES

       debian/package.files
	   Lists the files to be moved into a package, separated by whitespace. The filenames listed should be relative to debian/tmp/. You can
	   also list directory names, and the whole directory will be moved.

OPTIONS

       --sourcedir=dir
	   Instead of moving files out of debian/tmp (the default), this option makes it move files out of some other directory. Since the entire
	   contents of the sourcedir is moved, specifying something like --sourcedir=/ is very unsafe, so to prevent mistakes, the sourcedir must
	   be a relative filename; it cannot begin with a `/'.

       -Xitem, --exclude=item
	   Exclude files that contain item anywhere in their filename from being installed.

       file ...
	   Lists files to move. The filenames listed should be relative to debian/tmp/. You can also list directory names, and the whole directory
	   will be moved. It is an error to list files here unless you use -p, -i, or -a to tell dh_movefiles which subpackage to put them in.

NOTES

       Note that files are always moved out of debian/tmp by default (even if you have instructed debhelper to use a compatibility level higher
       than one, which does not otherwise use debian/tmp for anything at all). The idea behind this is that the package that is being built can be
       told to install into debian/tmp, and then files can be moved by dh_movefiles from that directory. Any files or directories that remain are
       ignored, and get deleted by dh_clean later.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
