So just change the time stamp 200906 become 200905.
Is it possible using script ?

Thanks

There should be a better soln.
Code:
ls *2009* |while read file
do
   nf=$(echo $file|sed 's/200906/200905/')
   mv $file $nf
done

Or use posixshell (ksh, bash,...) builtin replace without external sed.
Code:
for file in *200906*
do
    nf=${file/200906/200905} 
    # example how to check, have we done some change or not - if done, then rename
    [ "$nf" != "$file" ] && mv "$file" "$nf"
done

Try this...
Code:
ls -1 *200906* | sed 's/\(.*\)\(200906\)\(.*\)/mv & \1200905\3/'

if it gives u what u want...

Code:
ls -1 *200906* | sed 's/\(.*\)\(200906\)\(.*\)/mv & \1200905\3/' | sh
