*nix isnt windows... windows creates a "copy" file only macosX offers something similar since it downloads you dont know why sometimes files you only downloaded but just wanted to look at ( often PDF files...) adding (X) to the file name and incrementing X.

To my knowledge no modern unix would accept that you cp a file on itself, allowing it would end with a file size 0, so you must give second parameter and it should be at least an existing directory ( file is optional if keeping the same name )

Your only choice if you dont want to give a second parameter because the file will be in the same directory is to write a script where you use the the first param for the second adding an extension to the original file name

LHAPDF-GETDATA(1)						   User Commands						 LHAPDF-GETDATA(1)

NAME

       lhapdf-getdata - Get PDF sets from the LHAPDF repository

SYNOPSIS

       lhapdf-getdata [--main] [--all] [--repo=URL] [--dest=DEST] [--dryrun] <name|number> [<name|number> ...]

DESCRIPTION

       Grab PDF grid and param files from the LHAPDF repository and install them into the local LHAPDF data directory.

OPTIONS

       -h, --help
	      show this help message and exit

       --repo=URL
	      Base URL of online sets repository (http://www.hepforge.org/archive/lhapdf/pdfsets/current)

       --dest=DEST
	      PDF sets directory to install to (/usr/share/lhapdf/PDFsets)

       --all  Get ALL sets (this will be hundreds of megabytes... be careful!)

       --list Just list available files

       --force
	      Overwrite existing files

       --dryrun
	      Don't actually do any downloading

       -Q, --quiet
	      Suppress normal messages

       -V, --verbose

EXAMPLES

       Show all available sets:
	      lhapdf-getdata --list

	      lhapdf-getdata NNPDF

       Get CTEQ6L1, CTEQ66, MRST-S LO* and LO** PDFs with pattern matching:
	      lhapdf-getdata CTEQ6ll CTEQ66 lomod MCal

       Get MSTW2008 68% confidence PDF by full name:
	      lhapdf-getdata MSTW2008lo68cl.LHgrid

       See how much downloading would be involved in getting all PDF sets:
	      lhapdf-getdata --all --dryrun

       I'm hardcore, give me the whole collection:
	      lhapdf-getdata --all
