I have a folder on my desktop named Models. In the folder, there are named folders with jpeg files without the .jpg extensions. The jpeg file names are random hashes. I would like to use a bash script to batch rename these jpeg files to their directory names with increments and append the .jpg extension on each file.
It's basically something like
Models/
Alice/
a5ccB2ff3e
ee420bc4a
2acee54dc
...
Alex/
de33fa24c0
d1eaa48e0a
...
And I want to to be like
Models/
Alice/
Alice001.jpg
Alice002.jpg
Alice003.jpg
...
Alex/
Alex001.jpg
Alex002.jpg
...
