du --max-depth=1 -h
find . -maxdepth 1 -exec du -ks {} \; | sort -rn | head -n 15
I use two aliases for du:
alias dum='du --max-depth=1'
alias duh='du -h --max-depth=1'
dum signifies max-depth and duh signifies human-readable. "--max-depth=1" makes sure you get the disk usage for the complete directory and not for every individual ((sub)sub)subdirectory. Most of the time that is the info I want.
[email protected]:~/web$ duh
93K ./links
24K ./images
15M ./preken
1,1M ./studie
232K ./weblog
16M .
The human readable part does not work so well when sorting:
[email protected]:~/web$ duh | sort -rg
232K ./weblog
93K ./links
24K ./images
16M .
15M ./preken
1,1M ./studie
This sorts by numerical value, but the difference between a number with M or K at the end goes beyond sort. [BTW, I don't see any difference between 'sort -n' and 'sort -g'.] That's where the 'dum' alias comes in handy:
[email protected]:~/web$ dum | sort -rg
16058 .
14593 ./preken
1081 ./studie
232 ./weblog
93 ./links
24 ./images
