Shell Programming and Scripting

I need to write a script which will check all the directories in / and find out which is separate filesystem or a directory inside /
suppose i have
/application -->/dev/hdisk0 is a partitiom
/abc --> is a directory
/xyz-->is a directory
/db-->/dev/hdisk1 is a partition

actually my / gets full most of the time so i need to check the size of the directories inside / not the partitions (filesystems). so i am trying to write a script which will search all the directories only and can check size inside.
I think we can use Lost+Found for this, which is present only inside partitions.

check Lost+found
if Lost+found not present
du...
else
next step

Which OS are you on?

Depending on the OS, you could build the below logic:

1. Get a list of file systems using "bdf" or "df -k" as the case may be.

2. Get a list of all directories & file systems under /.

3. Compare the above 2 lists and eliminate the file systems.

4. Whatever remains must be the directories!

In HP-UX for example "du -x" confines to current filesystem.

To get disc usage in kb of all directories in root directory sorted with highest first:

Code:

du -kx / | sort -n -r | more
