Need a help on the getRuntime() function

Posted by lazyman on January 13, 2002 at 4:24 PM

I have a problem :

Process p=Runtime.getRuntime().exec("pr -l 61 a.txt> b.txt");

After I Run java Program, the file "b.txt" doesn't created.
Does anybody know why? It seems java Runtime doesn't know what is the ">"?

Thanks a lot!
