    printf '%s\n' "$file"
done

done

3. All directories on Desktop –

#!/bin/bash

for dir in ~/Desktop/*/; do
    printf '%s\n' "$dir"
done

4. Only these files – /Dir1/Dir2/File1, /Dir1/Dir2/File2, /Dir1/Dir2/Dir3/File3 –

#!/bin/bash

for file in /Dir1/Dir2/{File1,File2,Dir3/File3}; do
    printf '%s\n' "$file"
done

5. All files inside all nested directories –

#!/bin/bash

for file in ~/Pictures/**/*; do

shopt -u globstar
