[SOLVED] Rename files numerically in place, multiple folders

Issue

I am able to rename files numerically, in place, in multiple folders. However, it is not the result I am looking for. My file structure looks as follows:

Pictures-
    Vacation-
        img.001.jpg                                                    
        img.002.jpg                                                   
        img.003.jpg                                                    
    Holidays-
        img.004.jpg
        img.005.jpg                                                    
        img.006.jpg                                                   
    Fun-
        img.007.jpg

What I'd like to achieve is:

Pictures-                                                                   
    Vacation-
        img.001.jpg
        img.002.jpg
        img.003.jpg
    Holidays-
        img.001.jpg
        img.002.jpg
        img.003.jpg
    Fun-
        img.001.jpg

So far I have come up with the following:

a=1
for i in $vm/Holiday/*; do
    new=$(printf "%03d.jpg" ${a})
    mv ${i} $vm/Holiday/${new}
    let a=a+1
done

How can I achieve my desired result without having to separately run this on every single directory within my pictures folder?

Solution

Take your version and make it iterate over the folders as well.

#!/bin/bash

for dir in ~/code/stack/Pictures/*; do
        [ -d "${dir}" ] || continue
        i=1
        for img in "${dir}"/*.jpg; do
                [ -e "${img}" ] || break
                new="$(printf "%03d.jpg" "${i}")"
                echo mv "${img}" "$(dirname "${img}")/${new}"
                ((i++))
        done
done

Change the location of your Pictures folder and dryrun with the echo in place first. Is that what you wanted...?
