[Ubuntu-eg] how can i find duplicate files, folders ?

[Ahmed Kamal]

If you wanna code it for fun, enjoy. However if you want it to solve a
real-life problem, here is a simple one liner that may help

$ find . -exec md5sum {} \; 2>/dev/null | sort | tee md5.log | uniq -c -w
32 -d

This will print <repeat-count> <md5sum> <file-name>
Example:

      2 45d8a687baba5945db31936c171f49ed  ./HPIM1910.JPG

If you'd like to know what other files are duplicates of that file .. just
grep the checksum like

$ grep 45d8a687baba5945db31936c171f49ed md5.log
45d8a687baba5945db31936c171f49ed  ./HPIM1910.JPG
45d8a687baba5945db31936c171f49ed  ./koko.JPG

PS: Since checksumming files is not a fast process, storing results in that
log file is actually a good thing.
