Need help with runtime exe command

Question

Does anybody know how to get the command with double quotes to work with runtime exe?
String cmd = s+" "+fileName;
fin = new BufferedReader(new InputStreamReader(Runtime.getRuntime().exe(cmd).getInputStream()));
if my s is 'grep -i RTU', the fin would have correct value.
but if my s is 'grep -i "RTU"', the fin doesn't have anything (nothing return from exe(cmd) ).
I tried printing out the cmd, it looks fine ( grep -i "RTU" filename ).
Even when I copy the print of cmd and execute it on unix prompt, it return correct value too.
I also tried excaping double qoutes with backslash. Still doesn't work.
Thank you so much in advance

Answer 1

I tried with the exec(String[]) instead of
exec(String).
Still doesn't work.
I'm using Java 2 SDK, Standard Edition Version
1.3.1_02I am afraid I can't help. I can't duplicate your problem - I have no difficulty passing arguments with or without quotation marks using JDK 1.3. I just wrote a test to be sure, and it worked fine.
