I downloaded processing-2.0.1-linux64.tgz.

In Windows, when I download a non-install software (.exe) I locate it under Program Files directory so that it stays with other software. I don't want it to run in Downloads or somewhere else. I'm vety miticulous about my directory structure.

So in Ubuntu I want processing software to run just like firefox. I mean when I write 'proc' , it should show up in gnome activities window. I don't know where to locate a tgz file and contents of it? There is "Add downloaded package" in Synaptic file menu. I tried it however the tgz file was disabled, not clickable.

enter image description here

This is contents of processing-2.0.1 folder.

Firstly a .tgz file is not a program file. It is an gz compressed tar archive file, and as such is not runnable. Usually, this will be a source package and will need to be built.

It appears you have already expanded it into a directory. If not the command tar xzf processing-2.0.1-linux64.tgz' will expand it. I would copy or move it to/opt` and expand it there

From the contents it appears to be Java based program. And will fail if you don't have Java installed.

Open a terminal window and cd to directory where you have expanded the archive. Try running processing and processing-java. Remember which one starts the program as you want.

To run the program from the classpath (assumes expanded to /opt/processing-2.0.1) create the following file in a different directory. (I'll use the name processing ).

cd /opt/processing-2.0.1

Then run the following command to add make it executable it to /usr/local/bin.

sudo mv processing /usr/local/bin
sudo chmod +x /usr/local/bin/processing

You can also edit the menu to add a new item, or create a desktop icon. In either case you would use the full path to the program.

To understand where linux puts its file read the output of the command man hier.

I've already run the program. It works fine but it is in Downloads directory. I just asked where is the appropriate place to store it in (like firefox stored)? – Can Jul 7 '13 at 13:00
The appropriate place is /opt. I posted before my response was complete. The command sudo mv processing-2.0.1 /opt run from the Downloads directory should put it in the correct place. – BillThor Jul 7 '13 at 13:07
If you want to learn more about Linux filesystem directory structure, read the Wikipedia article on FHS: – soulsource Jul 7 '13 at 14:36
Ok it runs in /opt now. How to use Synaptic to handle this? There is "Add downloaded package" in Synaptic file menu. I tried it but the tgz file was not clickable. – Can Jul 9 '13 at 17:46
Synaptic is not the tool for running applications. Try searching for add apps to the panel for results like this.… – BillThor Jul 10 '13 at 0:35
