I am getting the follwing error:

ksh: /usr/bin/cp: arg list too long
The reason has nothing to do with AIX and everything with how the shell works: if you enter a "file glob" (like the "*" you used) it is not presented to the program but evaluated by the shell prior to feed its results to the program.

That means: if you enter the command as above and your directory holds only two files, "a" and "b", what the "cp" command would get is:

Code:
cp a b /application/program/files

(in case you wonder: "cp" would get "a" and "b" marked as both being source files).

In your case the list into which the asterisk expands is very, very long. Now, the command line in the shell is limited in length (as far as i remember it is 4k per default). This is why you get the error message.

The solution is to either use the directory name instead of "*" or use another utility: "find" or "tar".

With "find":

Code:
cd /your/source/directory ; find . -type f -exec cp {} /path/to/destination \;

or, with "tar":

Code:
# cd /your/source/dir
# tar -cf - . | (cd /your/destination/dir ; tar -xf - )

I hope this helps.

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.
