    Sorting using “sort -n” the output of “du -Sh” (“h” stands for “human-readable”) gives incorrect results: sizes are printed by “du” in float values with trailing unit indicator (none, “K”, “G”). For instance 1.2M is sorted as *lower* than 4.0K (since 1 < 4) which is false.

    So, instead of
    find /home/tecmint/Downloads/ -type f -exec du -Sh {} + | sort -rh | head -n 5
    You'd better use
    find /home/tecmint/Downloads/ -type f -printf "%s %p\n" | sort -rn | head -n 5
    which gives the 5 top size files.

      Oups! Didn’t noticed the “-h” option to “sort” too (which I didn’t knew BTW).
      So that’s OK.

      Thanks for the tip, will include your command as alternative way to achieve the same results with better format..

  2. Good advice. I’ve put together a tool that makes a lot of this even easier, in case anyone is interested.

    I expect that urls are not permitted in content, but are invited for one’s name, so I’ve placed the bitbucket link to my script, “duke” there.

      Thanks for sharing the duke tool, seems excellent with nice presentation of files sizes and their ages, will surely write about this duke tool on our next article. Could you please send more about the tool and features at
