Hi All,

I want to find the percentage occupied by the directory in the file system.
Say, i have the file system
/home/arun/work

/home/arun/work/yesterday
/home/arun/work/today
/home/arun/work/tomorrow

The size of the file system is
Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
/dev/hd4 983040 274052 73% 12126 3% /home/arun/work

Try out the command "du".
Code:
man du

When you get values, you can use arithmetics to add, subtract etc.

Java Thnx zaxxon,
du /home/arun/work/yesterday
du /home/arun/work/today
du /home/arun/work/tomorrow

all is giving the block size like
/home/arun/work/yesterday - 230
/home/arun/work/today - 598
/home/arun/work/tomorrow - 8754

and my file system /home/arun/work contains 123456 blocks.
In this i want to find what percentage of blocks was utilized by each of its directories like "yesterday", "today" and "tomorrow".

We have to calculate the size of the blocks which was consumed by all it sub-directories and files under the directories "yesterday", "today" and "tomorrow".

Please give me some suggestions to find this.

#!/bin/sh

# This is a command that will generate a space report.

du -sh * | sort -nr > $HOME/space_report.txt
