ij stdout and stderr

[Xavier Vigouroux <Xa...@Sun.COM>]

Hi,

I am using ij in a script. In some case the script is not executed 
correctly (transient PriviledgeException). I would like at least warn 
user about the problem.
but, as far as i see, ERROR are printed on stderr instead of stdout.

Do i need to make a grep "ERROR" or is  there another solution?

thanks

the problem is the other way....both streams are merged (there is no 
stderr)....
So I had to "grep" the stdout to extract errors and then redirect it to 
  stderr

When I run scripts on UNIX I typically run them like this to capture 
stderr in the output logfile:

    c shell:
    my_script_file >& file.log

    bourne shell:
    my_script_file > file.log 2>&1

does this help?
