Rename files in sub directories with sequential numbers
I can rename a file with sequential numbers from 1 to N with this script:

Code:
num=1
for file in *.dat;do
       mv "$file" "$(printf "%u" $num).txt"
       let num=num+1
done

The script begins with renaming a some.dat file to 1.dat.txt and goes on sequentially renaming other DAT files to 2.dat.txt, 3.dat.txt and so on.


This script works very well on my Linux system when I have one directory with all DAT files in it. But it cannot work when I have a parent directory with sub directories. My directory structure is like this:

Parent Directory and inside parent directory there are 20 more sub directories and inside those sub directories are the DAT files.

Is there any way I can modify the above script so that (I am in my parent directory and run this script) it takes in one sub-directory and renames all the files in that directory in sequential numbers say 1 to N, then goes to another sub-directory and renames from N+1 to M, then goes to third sub-directory and renames from M+1 to X and so on?

git-mv

GIT-MV(1)							    Git Manual								 GIT-MV(1)

NAME

       git-mv - Move or rename a file, a directory, or a symlink

SYNOPSIS

       git mv <options>... <args>...

DESCRIPTION

       This script is used to move or rename a file, directory or symlink.

	   git mv [-v] [-f] [-n] [-k] <source> <destination>
	   git mv [-v] [-f] [-n] [-k] <source> ... <destination directory>

       In the first form, it renames <source>, which must exist and be either a file, symlink or directory, to <destination>. In the second form,
       the last argument has to be an existing directory; the given sources will be moved into this directory.

       The index is updated after successful completion, but the change must still be committed.

OPTIONS

       -f, --force
	   Force renaming or moving of a file even if the target exists

       -k
	   Skip move or rename actions which would lead to an error condition. An error happens when a source is neither existing nor controlled
	   by GIT, or when it would overwrite an existing file unless -f is given.

       -n, --dry-run
	   Do nothing; only show what would happen

       -v, --verbose
	   Report the names of files as they are moved.
