Welcome to, the personal homepage of Brandon Purcell. I started building many, many years ago to share information I ran across everyday in my role as a Support Engineer and Consultant for Macromedia/Adobe. As a support engineer and consultant I always had a lot to blog about but as I moved into managment roles at Adobe my technical content dwindled.

I currently work as the Director of Technology for Universal Mind. My primary responsiblity is managing the SpatialKey project and it has been an amazing experience. I have been spending a lot of time working with Amazon Ec2 and will share my experiences through the blog in the future. I truly believe that Cloud Computing is the IT platform of the future and we have built the SpatialKey architecture on top of Ec2.

I was running out of space on a server the other day and was wondering what directory was full and what files I could clean up. There is a simple command that is helpful to identify usage by directory. This works from within any directory so you can walk the path from / down through your largest directories and look for files to clean up.

[root@localhost]# du -hc --max-depth=1
4.0K ./misc
4.0K ./srv
576K ./root
29M ./sbin
16K ./tmp
2.0G ./usr
731M ./proc
12M ./boot
0 ./sys
379M ./appserver
28M ./opt
447M ./var
85M ./lib
8.0M ./etc
11M ./home
0 ./selinux
6.3M ./bin
16K ./lost+found
40K ./dev
24K ./mnt
3.7G .
3.7G total


Thanks, good to know.

Also, if you're in X there are some GUI tools that give a nice visual pie chart of usage on your drive.

Filelight (QT app) and Baobab (GTK/Gnome app).
