There are many ways to skin a cat. For renaming extensions,
this script should do fine. You seemed to have googled some
geeky site. Actually the mv line within a loop is enough !
---------------<snip>-------------------
#!/bin/bash
# Renaming File Extensions Script (rfes)
# Usage: rfes old_extn new_extn
if [ $# -ne 2 ]
then
echo "Usage: `basename $0` old_suffix new_suffix"
exit 1
fi
for file in *.$1
do
mv $file ${file%$1}$2
done
exit 0
--------------</snip>---------------------
For your requirement of changing the extension dynamically
with extension increments see if you can generate the new
extension, instead of using $2 ... do it as homework :-)
Not difficult if you get the idea !
Come back on personal mail, if you get stuck.

Or :$echo "scale=4; (17 / 3) + 0.517" | bc ### 'real' maths
Note:'scale' is the decimal round off figure (real numbers).
