Both are almost perfect Smilie.
My version use dynamic filenames, your teams dynamic replace rule.
Your team version not chech, is there name change or not. My version check it.

So this is the best:
Code:
#!/bin/sh
#rename.sh
# arg1=old string
# arg2=new string
# arg3-n = files to make name editing
old="$1"
new="$2"
# remove 2 args, rest are filenames
shift 2
for f in $*
do
      newname=`echo "$f" | sed "s/$old/$new/" `
      if [ "$newname" = "$f" ] ; then
           echo "no rename $f"
           continue
      fi
      echo "rename $f -> $newname"
      mv  "$f"  "$newname"
done

Using:
Code:
./rename.sh "grp_eclp_" "grp_ecl_"  grp*ADTA*.xlt

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list. Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1). FILES
