My IDE of choice for developing lately has been Komodo Edit. It's lighter than Eclipse and does what I need it to do. Installing and updating on most OS's is easy but on my Ubuntu installation I always have to do a few more tricks to make everything work just right. This post is to help me remember exactly the steps of installing and updating so that I don't need to Google it every time.

1. Download the latest version of Komodo Edit
2. tar xvzf Komodo-Edit-8.5.2-13850-linux-x86.tar.gz Update this to your downloaded version
3. cd Komodo-Edit-8.5.2-13850-linux-x86
4. sudo ./install.sh
5. When prompted for installation location enter /opt/Komodo-Edit-8/
6. If you already have Komodo Edit installed in that location run sudo rm -r /opt/Komodo-Edit-8/ to uninstall it first.
7. export PATH="/opt/Komodo-Edit-8/bin:$PATH"
8. Search for it in your Dash and all should be good.

Hope this helps someone else, I know it will help me.
