Script that goes through files in a directory AND subdirectories

Question

I have a simple problem to which I don't find the answer on the net.

Like the title states it, I would like to go trough all the files in a directory AND his sub-directories. I know how to do it with find command but I would like to know how to do it with a simple for loop.

I initially have this line :

for file in $dir/*.png; do

And I'm sure there is a way to have some kind of $dir/*/*.png line that makes it possible with a for loop.

Thanks for your answers.

Hi, is there any specific reason to avoid using the find command? It makes life easier to use any decent tools available. — Krassi Em

just a for loop won't help you (you don't know levels of directory hierarchy). Without find tool, you may try to go with a recursive function — RomanPerekhrest

Thanks, I suppose there is no choice but to use that find command.
