Display top ten directories by size
Hi,
I am new to Unix.
I want to display top 10 folders by size.
I tried with
du -ksl * | sort -nr | head -10
command .But I am getting the following error

-bash: /usr/bin/du: Argument list too long

Can some one help me.
Thanks.

if you have Python on your system, you can try this script (example 5).

use the below code:-


Code:
df -ah | nawk '(NR>1){match($3,"[0-9]*.[0-9]*") ; print r=substr($3,RSTART,RLENGTH)}'| sort -r | head -10

I working in the below system:-

SunOS server8 5.10 Generic_118833-36 sun4u sparc SUNW,Sun-Blade-100


or in a more general form use:

Code:
df -ah | nawk '(NR>0){match($3,"[^.]*.[^.]*") ; print r=substr($3,RSTART,RLENGTH)}' | sort -r | head -10

df? Whatever this produces doesn't work on Solaris 8 or on AIX (and I'm guessing Linux either).

What operating system are you using, Satyak? I would guess AIX (or Linux) as "du -ksl" doesn't work on Solaris.

If you are using AIX, and you're able to, you can increase the arg list limit:

For example:
Code:
chdev -l sys0 -a ncargs=128

(or the equivalent for your OS)

use du -ksl, not du -ksl *. Almost same, but not for du.
du | sort -nr | head -10

Heavy diskusers ?
Code:
ls -alR | awk '
   /^-/ { users[$3]+=$5 } # take regular files only

   END {
        for (user in users) {
                print user,users[user]
                }
       }
  ' | sort -t " " -k 2,2nr | head -10

If you are only interested in total size of directories in current directory (including any subdirectories under those directories):

Code:
find "`pwd`"/* -prune -type d -print 2>/dev/null|xargs du -ks|sort -nr|head -10
