Recursively iterating through subdirectories and removing certain file - bash

Question

I have a music archive with lots of folders and sub-folders (Cover Art etc.) so instead of manually removing hundreds of Folder.jpg, Desktop.ini and Thumb.db files, I decided to do a simple bash script but things got really messy.
I did a simple test by creating dummy folders like this:
/home/dummy/sub1 -
sub1sub1
sub1sub1sub1
sub1sub1sub2
sub2 -
sub2sub1
sub2sub2
sub2sub2sub1
and copied some random .jpg, .mp3, .ini files across these folders. My bash script looks currently like this:
function delete_jpg_ini_db {
if [[ $f == *.jpg ]]; then
echo ".jpg file, removing $f"
gvfs-trash $f
elif [[ $f == *.ini ]]; then
echo ".ini file, removing $f"
gvfs-trash -f $f
elif [[ $f == *.db ]]; then
echo ".db file, removing $f"
gvfs-trash -f $f
else echo "not any .jpg, .ini or .db file, skipping $f"
fi
}
function iterate_dir {
for d in *; do
if [ -d $d ]; then
echo "entering sub-directory: $d" && cd $d
pwd
for f in *; do
if [ -f $f ]; then #check if .jpg, .ini or .db, if so delete
delete_jpg_ini_db
elif [ -d $f ]; then #enter sub-dir and iterate again
if [ "$(ls -A $f)" ]; then
iterate_dir
else
echo "sub-directory $f is empty!"
fi
fi
done
fi
done
}
pwd
iterate_dir
When I run it, it successfully iterates through sub1, sub1sub1 and sub1sub1sub1, but it halts there instead of going back to home and searching sub2 next.
I am new in Bash scripting, all help is appreciated..
Thanks.

Answer 1

And in one command you can run:
find /home/dummy/sub1 -name "*.jpg" -o -name "*.ini" -o -name "*.db" -delete
And if you want to see which files would be deleted, replace -delete with -print (just filenames) or with -ls (like ls -l output).

here is the changed code....
function delete_jpg_ini_db {
if [[ $f == *.jpg ]]; then
echo ".jpg file, removing $f"
gvfs-trash $f
elif [[ $f == *.ini ]]; then
echo ".ini file, removing $f"
gvfs-trash -f $f
elif [[ $f == *.db ]]; then
echo ".db file, removing $f"
gvfs-trash -f $f
else echo "not any .jpg, .ini or .db file, skipping $f"
fi
}
function iterate_dir {
for d in *; do
if [ -d "$d" ]; then
echo "entering sub-directory: $d" && cd $d
pwd
for f in *; do
if [ -f "$f" ]; then #check if .jpg, .ini or .db, if so delete
delete_jpg_ini_db
elif [ -d $f ]; then #enter sub-dir and iterate again
if [ "$(ls -A $f)" ]; then
iterate_dir
else
echo "sub-directory $f is empty!"
fi
fi
done
cd ..
fi
done
}
pwd
iterate_dir
Mistakes
You did have support for file name with space in them
You did not navigate back after your inner for loop..
Try it...
