I have n number of files I want to rename by removing a particular name, whitespace, and I want to add a unique string with the new name:
E.g.
"MPKL 100055.jpg"
"MPKL 200452.jpg"
"MPKL 500002_thumb.jpg"
I want to rename the above files to:
"00100055.jpg"
"00200452.jpg"
"00500002_thumb.jpg"
Two zeros have to come in front of the existing number.
