How to find Top 10 Big files/Folder in the system?


Used following command to find out the top 10 big files in the system But it is having its own limitations as it consider files and directories both.
Code:
du -a / | sort -n -r | head -n 10
I would like to get the following information.

1)top 10 big files.
2)top 10 big directories.

File size with human readable output.
as executing
Code:
# du -a / | sort -n -r | head -n 10
5546667 /
2755464 /usr
2211844 /install
2136888 /install/linux-3.0-rc1
1508756 /usr/share
834836  /install/linux-3.0-rc1/drivers
716544  /usr/lib
365224  /lib
331924  /lib/modules
317132  /usr/share/locale
Giving me correct output
but when i add -h option for human readable file size its giving me wrong output.
Confused why its happening any clue?
Code:
# du -ha / | sort -n -r | head -n 10
1020K   /lib/modules/3.0.0-rc1/kernel/drivers/net/e1000/e1000.ko

You ca also give below command

du -sh *|grep M|more

or

du -sh *|grep G|more

G for files which are in gigabytes and M for file in megabytes

You are not sorting the output here.
Anyway thanks for sharing.

Which version of sort are you using? Here is mine
Code:
$ sort --version
sort (GNU coreutils) 8.5

Briefly, sort is not a human. If you want sort to sort correctly, you have to feed it data in a form that it can work with. It doesn't know that, in this context, a K is worth 1000 (or is it 1024?) of not-a-suffix counts, and that an M is worth 1000 (or 1024) K counts.

The simplest thing is to stick with the non-human-readable form, but, if you really wanted you could
  • look at the 'G's first, count them, subtract from the total, move on to the 'M's, etc
  • work on the numbers in n-h-r form and convert them at the end (easier if k=1000, etc), for the human to read
neither of the above seem worth the effort, to me, but YMMV

Well, you are using a very old version of sort. Apparently sort did not have the '-h' option back then. Any chance that you can upgrade to the latest version?

Well, that depends on which system you are using. Normally your update-manager should keep it up to date. If this is not the case then *maybe* newer versions are not compatible with your system.
