Renaming File Names in a folder/Dir

Hi Team,
I'm new to Unix shell scripting .
I've the following requirement

A folder contains the list of files with the following format

I have to rename the above file to like below

Could you please give me some idea to rename the file (not the content in the file )
# 2  
What shell are you using? Using bash or ksh93:
for i in*
 echo mv "$i" "$new"

Remove the echo when satisfied with the command lines.

You seem to be using ksh88, not ksh93.
for i in*
 new=$(echo "$i"|sed 's/^ab/BOX/;s/\./_/g')
 echo mv "$i" "$new"
