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?

mvdir

mvdir(1)						      General Commands Manual							  mvdir(1)

NAME

       mvdir - Moves (renames) a directory

SYNOPSIS

       mvdir directory1 directory2

DESCRIPTION

       The  mvdir  command renames directories within a file system. To use mvdir, you must have write permission to directory1 and directory2 and
       to the parent directories of directory1 and directory2. The directory1 argument must name an existing directory.  If  directory2  does  not
       exist,  directory1  is moved to directory2.  If directory2 exists, directory1 becomes a subdirectory of directory2.  directory2 cannot be a
       subdirectory of directory1.

       Directories cannot be moved across file systems.

       You can also rename a directory with the mv command.

NOTES

       This command was made obsolete by the mv command.

EXAMPLES

       To rename or move a directory to another location, enter: mvdir appendixes manual

       If manual does not exist, then this renames the directory appendixes to manual.

       If a directory named manual already exists, this moves appendixes and its  contents  to	manual/appendixes.   In  other	words,	appendixes
       becomes a subdirectory of manual.

SEE ALSO

       Commands:  mkdir(1), mv(1)

       Functions:  rename(2)
