Hi.

Alternatives with rename and mved:

Code:

#!/usr/bin/env bash

# @(#) s1	Demonstrate easy mass rename with similar pattern files.
# mved: see http://www.efball.com/linux/mved/mved (shell), or  http://raf.org/mved/ (perl)

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C rename mved

# Remove debris, create new files.
renew () {
  rm -f *.{txt,dat}.gz
  touch file{1,2,3}.txt.gz
}

pl " Current situation:"
renew
ls *.gz

pl " Results from rename:"
rename 's/txt/dat/' *.gz
ls *.gz

pl " Renewed current situation:"
renew
ls *.gz

pl " Results from mved script:"
mved =.txt.gz =.dat.gz
ls *.gz

exit 0
