processing file names using text files

Hi,

I have to perform an iterative function on a set of 10 files. After the first round the output files are named differently than the input files.

examples

input file name = xxxx1.yyy
output file name = xxxx1_0001.yyy

I need to rename all of the output files to the original input name for reprocessing.

I have created two text files using ----

ls > output.txt
ls > input.txt

Now what I would like to do is assign line one of output to say $1 and input to $2 and then use the shell command

cp $1 $2

where the file listed on the first line of output.txt is cp to the file name givin in the first line of input.txt

and for this to be done for each line of the two files.

I have been trying to use an awk script

#!/usr/bin/awk -f
{d=$0}
{print d }

but I cannot figure out how to assign input file to "d" and output to "e" to then pass those variables to the shell cp command.

can anyone help me? and yes as you probably can tell, I'm very new at this.

xzless

XZLESS(1)							     XZ Utils								 XZLESS(1)

NAME

       xzless, lzless - view xz or lzma compressed (text) files

SYNOPSIS

       xzless [file...]
       lzless [file...]

DESCRIPTION

       xzless  is  a  filter  that  displays text from compressed files to a terminal.	It works on files compressed with xz(1) or lzma(1).  If no
       files are given, xzless reads from standard input.

       xzless uses less(1) to present its output.  Unlike xzmore, its choice of pager cannot be altered by setting an environment variable.   Com-
       mands are based on both more(1) and vi(1) and allow back and forth movement and searching.  See the less(1) manual for more information.

       The command named lzless is provided for backward compatibility with LZMA Utils.

ENVIRONMENT

       LESSMETACHARS
	      A list of characters special to the shell.  Set by xzless unless it is already set in the environment.

       LESSOPEN
	      Set to a command line to invoke the xz(1) decompressor for preprocessing the input files to less(1).

SEE ALSO

       less(1), xz(1), xzmore(1), zless(1)
