Here a small piece of code which will search for the duplicates in the path you supply. It will generate a new file which contains the commands for deleting those duplicates.
Make sure you double check the resulting file!
The script requires that you have fdupes installed.
Install it in Ubuntu/Debian by running the following command in your terminal:
sudo aptitude install fdupes
#!/bin/bash OUTF='rm-dups.sh' echo "#!/bin/bash" > $OUTF fdupes -r -f $1 | sed -r 's#(.+)#rm '\"'\1'\"'#' >> $OUTF chmod +x $OUTF
