Auto close or overwrite browser tabs opened through the command line

Question

I have a shell script creating an html page. It then opens in a web browser using simple syntax

opera result.html 

However, if I run this script several times, I get as many tabs / windows as it works. I tried loading another page containing a script that opens "result.html" to a specific target window, but this script page would not be closed using window.close () or self.close () [presumably because it was not javascript is open ...], so the script page is repeated ...

Is there a way for the web browser to open the file on the target using the command line or automatically close the window opened through the command line?

What platform are you using? For Unix, there is a -activetab switch that you can use.

 opera -activetab result.html 

See Opera command-line options for various platform switches that may be appropriate.
