    It appears that if you use -h (human readable) with du, the sort gets confused as it doesn’t interpret the decimal unit prefix (i.e. the G, M, or K) properly, and you get the largest displayed numeric value.

    For example: 9G, 10K, 8K, 4M, 7G would sort to 10K, 9G, 8K, 7G, 4M.

    I noticed this when I got the following results:

    # du -h /data.source/ | sort -n -r | head -n 5
    1020K   /data.source/mod_tile/default/9/0/0/1/176
    1020K   /data.source/mod_tile/default/10/0/0/1/178
    1016K   /data.source/mod_tile/default/11/0/0/35/65
    996K    /data.source/mod_tile/default/9/0/0/16/170
    992K    /data.source/mod_tile/default/9/0/0/1/160
    # du /data.source/ | sort -n -r | head -n 5
    680595148       /data.source/
    597114072       /data.source/pgsql
    597114068       /data.source/pgsql/9.6
    597114060       /data.source/pgsql/9.6/data
    595032120       /data.source/pgsql/9.6/data/base
