2.0 Starting the IDV for the first time

Once the IDV has been installed, you can start it from the command line.

Starting the IDV using the runIDV script.

Open a terminal window (if you do not have one open already) and change to the directory where the IDV was installed. (e.g., /home/idv/IDV_7.0u1)
Print out the runIDV script.
On Unix/Mac:
On Windows:
You should see a printout that ends like this:
On Unix:
```
command="java -Xmx${idv_memory}m -Didv.enableStereo=false -jar ${dirname}/idv.jar $*"
    
```
and then some code to find the version of java to use.
On Windows:
```
jre\bin\java -Xmx%idv_memory%m -Didv.enableStereo=false -jar idv.jar %*
    
```
The script sets up the environment for the IDV to run. Details

The IDV has many command line arguments which can be passed to the runIDV script. To get a listing, run the following command:

./runIDV -help

You should see a printout like this:

        -help  (this message)

For this workshop, we are going to only use the -installplugin argument to load some workshop specific configuration files from a plugin. (You will learn more about plugins later in the workshop).
To start the IDV for the workshop the first time, type (Cut and Paste tip ) :
While the IDV is starting, you will see the following splash screen:
When the IDV starts for the first time, you will see 3 windows:
- IDV Help Tips window. An optional window with tips on using the IDV.
  
  For now, close the IDV Help Tips window by clicking the Close button. We'll look at this in a later exercise.
- Dashboard window. Used for selecting data to analyze and visualize.
- Unidata Workshop IDV window. This is the main window for displaying data visualizations.
Now we are ready to explore the user interface.
