Open .pde files with Arduino IDE in Linux

After I installed the Arduino IDE I found out that I could not run "arduino test.pde" to open an existing sketch. The previous command would just open a blank sketch.

To fix this problem you have to edit the Arduino startup script, which in my case is located at "/usr/share/arduino/arduino". The last line of this file looks like this:

java -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel processing.app.Base

and it needs to be changed to this:

java -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel processing.app.Base "$*"

Finally I had to change my "/usr/bin/arduino" from:

/usr/share/arduino/arduino

to

/usr/share/arduino/arduino "$*"

Now you should be able to associate .pde files with the Arduino IDE and have them automatically open.
