Recursive switch now needed/available. File paths with spaces.

[trimitri]

Great script, thanks for sharing!

I needed to do some adjustments for allowing file paths with spaces. Also, with the new(?) recursion option in findimagedupes, a more streamlined approach could be used:

Calling the script:

findimagedupes --recurse -t 94% --program /home/tmp/rm_dupes.sh folderA folderB

The rm_dupes.sh script, now smaller:

#!/bin/bash

deletefiles=false

echo -e "! deletefiles is set to $deletefiles"

prevSize=0

# split each line by whitespace, loop through and check each file size, select the largest file to keep
for thisEntry in "$@"
do
	dupesFound=$((dupesFound+1))
	echo - statting "$thisEntry"...
	thisSize=$(stat --printf="%s" "$thisEntry")
	echo - single found item is "$thisEntry" with file size of "$thisSize" bytes
	# find largest file
	if [[ "$thisSize" -gt "$prevSize" ]]; then
		fileToKeep=$thisEntry
	fi
done
echo - largest file is "$fileToKeep", this file will be kept when deleting duplicates
dupesFound=$((dupesFound-1))
echo ---

# now find the files to delete
for thisEntry in "$@"
do
	# find largest file
	if [[ "$thisEntry" != "$fileToKeep" ]]; then
		echo - file to be deleted is "$thisEntry"
		# delete file if --delete is passed in
		if [[ "$deletefiles" == "true" ]]; then
			echo -e " - deleting duplicates"
			rm -v "$thisEntry"
			deletedFiles=$((deletedFiles+1))
		fi
	fi
done
echo -----
echo -e " - $dupesFound duplicates found, not including largest original file"
echo -e " - $deletedFiles files deleted."
