unzip question (OS X)

[Christian Langers]

Hello,

Does anybody know what option to set to the unzip shell command in  
order do get an incrementation  to the file to extract (stored in a  
stack) when there is a file with the same name ? (unzipping via the  
Finder gives me that automatically : e.g. XML exists --> unzipping :  
XML 1 --> unzipping : XML 2...)


In my script I verify if there is already a file with the same name  
then I have to possibilities :
- shell (if there is no such file)

     put the cProg of this cd into url ("binfile:"&tPath&"/"&tName)
      put "cd "&tpath&cr&"unzip "&tName into tShell
       get shell(tShell)

- Applescript (if there is such a file)

     put the cProg of this cd into url ("binfile:"&tPath&"/"&tName)
      put "tell application"&&quote&"Finder"&quote&cr&"open file "&q 
(tName)&cr& "end tell" into tAppScript
       do tAppScript as Applescript

With Applescript I'm getting the increments but I want this to happen  
"quietly" (and in the shell)...


Any ideas ?

Thanks in advance,
