Whose suggestion about what?

 comp.unix.shell: trying to redirect both std out and err to a file toget=

her

and still err to a separate file


This is easy to do with shell constructs.

import java.util.Locale;
import java.util.Date;
import java.text.DateFormat;
 
// __
 
public class Test{
 
 public static void main(String[] args){
  DateFormat DF = DateFormat.getDateInstance(DateFormat.FULL, Locale.FR=

ANCE);

You should follow the coding conventions, at least mostly.

// __ std out

  System.out.println("// __ out.println: |" + DF.format(new Date()) + "|"=

);

What are you trying to accomplish here?

  DF = DateFormat.getDateInstance(DateFormat.FULL, Locale.CHINESE);
 
// __ std err
 
  System.err.println("// __ err.println: |" + DF.format(new Date()) + "|"=

);

 
// __ Exception in thread "main" java.lang.NullPointerException
 
  DF = null;
  DF.format(new Date());


What are you trying to accomplish here?

 }
}
 
/*
rm -f *.log
 
export _DT=`date +%Y%m%d%H%M%S_%s`
echo ${_DT}
 
(javac Test.java 2>&1 >&3 | tee ${_DT}"_errc.log" >&3) 3> ${_DT}"_errc.lo=

g"

Your use of quotation marks here is superfluous.

I would have to review this shell command, but it looks weird
to me. I don't normally go for such outr=E9 file-descriptor manipulation
so it will take time and effort to sort all that stuff out.

(java Test 2>&1 >&3 | tee ${_DT}"_err.log" >&3) 3> ${_DT}"_err_out.log"
 
ls -l *.log
cat *_err.log
cat *_err_out.log
*/


Glad it did what you want, though, whatever that was.
Hard to tell when the message is not in its thread context.
