trying to redirect both std out and err to a file together and still err to a separate file

[qwertmonkey]

I tested your suggestion with some java code and it works nicely

I tested your suggestion with some java [sic] code and it works nicely

Whose suggestion about what?

comp.unix.shell: trying to redirect both std out and err to a file together
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.FRANCE);

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?

}
}

/*

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.log"

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 outré 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.
