Size(k) of directories(Biggest first)

find . -depth -type d -exec du -s {} \; | sort -k1nr
somewhat faster version to see the size of our directories. Size will be in Kilo Bytes. to view smallest first change '-k1nr' to '-k1n'.

ncdu (package name:ncdu) is also nice if you find yourself needing to do this repeatedly and/or interactively.

So, why not just: du -k | sort -nr

@0JM, We have lot of way to display size, but I think 'find' is handling Tree traverse better than others. '-depth' is pretty good here, It makes 'du' first calculate inner directories then when outer directories comes, kernel cache helping 'du' to do faster calculation.

@mohan43u Yeah, there are multiple ways, but the find/exec combination is slow as hell. Try yourself: First, create some test-directories: for n in `seq 1 1 10`; do for m in `seq 1 1 10`; do mkdir -p $n/$m; done; done Then check performance: time find . -depth -type d -exec du -s {} \; | sort -k1nr >/dev/null real 0m0.398s user 0m0.136s sys 0m0.239s time du -k | sort -nr > /dev/null real 0m0.025s user 0m0.007s sys 0m0.018s Case closed.
