Suppressing error msgs from cmd-line.

[Lax]

Hello all,
From my Java program, I'm constructing a cmd-line one-liner and
running it from the shell on various platforms.

Is there any platform independent way to suppress error messages from
the cmd-line?
e.g., if the program does a "ls somefile.txt" on Unix and an analogous
"dir somefile.txt" on WIN, I want to suppress the error msgs, if
somefile.txt is not present.

In Unix, I could do a "ls somefile.txt 2> /dev/null".
But, is there a platform independent way to do the suppression.

Alternatively, how does one suppress the error msgs from WIN cmd?

Thanks for your time,
Prab

Yes: Write a Java program

Alternatively, how does one suppress the error msgs from WIN cmd?

dir somefile.txt 2> nul

(I'm not quite sure if error redirection works on win95)
