This question already has an answer here:
I have multiple folders and each one have around 175 files in it. file names are like
1.wav 2.wav 3.wav ...... 175.wav
I have to rename them as
A1.wav A2.wav A3.wav ...... A175.wav
In other words I have to append Letters in previous file names.
I am wondering if there is a easy way to do this.
Ubuntu Version is 16.10
