In folders and subfolders, I have a bunch of images named by date. I'm trying to come up with a script to look into a folder/subfolders and rename all jpg files to add the folder name.

Example:

/Desktop/Trip 1/200512 1.jpg

/Desktop/Trip 1/200512 2.jpg

would became:

/Desktop/Trip 1/Trip 1 200512 1.jpg

/Desktop/Trip 1/Trip 1 200512 2.jpg

I tried tweaking this script but I can't figure out how to get it to add the new part. I also don't know how to get it to work on subfolders.

#!/bin/bash
# Ignore case, i.e. process *.JPG and *.jpg
shopt -s nocaseglob
shopt -s nullglob

cd ~/Desktop/t/

# Get last part of directory name
here=$(pwd)
dir=${here/*\//}
i=1
for image in *.JPG 
do
   echo mv "$image" "${dir}${name}.jpg"
   ((i++))
done

  • @souser I don't understand, I don't wish to rename to lowercase but to add the subfolder name – user1081491 May 13 '20 at 00:12

Using find with the -iname option for a case insensitive match and a small script to loop over the images:

find /Desktop -iname '*.jpg' -exec sh -c '
  for img; do
    parentdir=${img%/*}      # leave the parent dir (remove the last `/` and filename)
    dirname=${parentdir##*/} # leave the parent directory name (remove all parent paths `*/`)
    echo mv -i "$img" "$parentdir/$dirname ${img##*/}"
  done
' sh {} +

This extracts the parent path for each image path (like the dirname command) and the directory name (like basename) and constructs a new output filename with the parent directory name before the image filename.

Remove the echo if the output looks as expected.

Try the following in your for loop. Note that '' is used to that the script can deal with spaces in the file names. 

for image in "$search_dir"*.JPG
do
    echo mv "'$image'" "'${dir} ${image}'"
done

  • Thanks, this worked for getting it to rname in the current folder. IS there a way to make it work on subfolders too? I think I would need the -R or -regex flags, right? But where would I place it? – user1081491 May 13 '20 at 00:45
