NEW STEP BY STEP MAP FOR HELLO001

I need to include a quantity just before the extension in the documents having a Bash script. such as, I need to convert a file name like abc.efg to abc.001.efg. the issue is always that I don't know exactly what is the extension of the file (it is without doubt one of the parameters on the script).
