How to batch rename files (.jpg) randomly?

Question

Ok, so I have a digital photo frame that I have, and view my photos from a USB. Everything works fine, however, there is no way to display the pictures randomly. So, I have to watch my pictures in order, which is fine but not really what I want.

I am wondering if there is a way to have my .jpg pictures, that I view to be batch renamed, but renamed randomly? Be it adding random characters to the start of the name or replacing the characters before .jpg

Thank you for your time and answers.

Answer 1

I suppose the following could work. Assuming the prefix of your filenames is "DSC" you can use the following command in the terminal (untested!)

cd /path/to/photos
rename 's/DSC/'$RANDOM'/' *.jpg

This uses the perl rename command to match regular expressions and replace them. In this case, we are substituting "DSC" with a random number in the filename for all .jpg files. Change the "DSC" to whatever your photos' prefix is.

another method (also untested) is with a bash script:

#!/bin/bash
for f in *.jpg; do
  mv "$f" $RANDOM-"$f"
done

Answer 2

#!/bin/bash    
for img in *.jpg; do
newname=$(head /dev/urandom | tr -dc a-z0-9 | head -c 8)
mv "$img" "$newname".jpg
done

This will shuffle all jpg files to random names.

Following one line script works for file names with white chars.

for f in *.jpg; do mv -n "$f" "${f/*/$RANDOM.jpg}"; done
