finding my lost linux disk space without adding software

I can run scripts on stock redhat 5 boxes.

I am looking for a good du script or two to find out what eats up the disk space by
large file
full directory

Here is what I found with google

Sudo
 
 
 
du  -s *      | sort -n
 
du -x --block-size=1024K | sort -nr | head -10


I am looking for a better script as well as how not to mess with /proc

It is more like troubleshooting.

First, issue command
df -hT

This will show you the percentage of used partitions.  Once you know which partition is of concern, you can use find command to find large files in that location, say /home

Then you issue command
find /home -type f -size +1G

This will show you files bigger than a GB.  If you have too many of these, you can then change your criteria like -size +10G or so.  You will be able to find the big files.

Fuser md lsof can be used to track a process that may have an open filehandle to a file that was deleted.  A soon as the processID restarted. The space is reclaimed by the filesystem.
lsof -f /var
