Hammer & Screwdriver What about this thinking?

The following example
shows files that start file7
creates a file, by using awk, containing current names and desired new names
shows that work file
reads through the work file, copying from original to new names
shows that the files were just created

Code:
> ls file7*
file70  file71  file73  file74  file75  file77  file78  file79

> ls file7* | awk 'd=$0 {print d" "substr(d,1,4)"new"substr(d,5,2)}' >list7

> cat list7
file70 filenew70
file71 filenew71
file73 filenew73
file74 filenew74
file75 filenew75
file77 filenew77
file78 filenew78
file79 filenew79

> while read file1 file2; do cp $file1 $file2; done <list7

> ls filenew*
filenew70  filenew71  filenew73  filenew74  filenew75  filenew77  filenew78  filenew79

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) Tukaani 2010-09-27 XZLESS(1)
