oh.. after your answer I just made sense of the question. it seemed like an options question so I though the options were missing.

Also I'll go with your answer pipe it to the null device /dev/null.

[ramesh]

The answer is in fact &> error_msg which will direct output only to the file error_msg and not to the screen.

For the life of me I though the answer was > /dev/null when I first saw the question. If someone can tell me why this is wrong I would appreciate it.

As I know it > /dev/null sould eliminate the error message completely, so that it is not redirected anywhere....?
