should help you out Take a look at the MSBUILD.EXE command line arguments page. Specifically the consoleloggerparameters switch.
You can use /clp:ErrorsOnly to display only errors in the console output.

Write STDOUT & STDERR to a logfile, also write STDERR to screen

fixed the issue. Will look into that further I would like to run several commands, and capture all output to a logfile. I also want to print any errors to the screen (or optionally mail the output to someone).

code :

(./doit >> log) 2>&1 | tee -a log

Can you make a python subprocess output stdout and stderr as usual, but also capture the output as a string?

may help you . , This example seems to work for me:

code :

# -*- Mode: Python -*-
# vi:si:et:sw=4:sts=4:ts=4

import subprocess
import sys
import select

p = subprocess.Popen(["find", "/proc"],
    stdout=subprocess.PIPE, stderr=subprocess.PIPE)

stdout = []
stderr = []

while True:
    reads = [p.stdout.fileno(), p.stderr.fileno()]
    ret = select.select(reads, [], [])

    for fd in ret[0]:
        if fd == p.stdout.fileno():
            read = p.stdout.readline()
            sys.stdout.write('stdout: ' + read)
            stdout.append(read)
        if fd == p.stderr.fileno():
            read = p.stderr.readline()
            sys.stderr.write('stderr: ' + read)
            stderr.append(read)

    if p.poll() != None:
        break

print 'program ended'

print 'stdout:', "".join(stdout)
print 'stderr:', "".join(stderr)

What is the best to detect stderr output and stop make

hop of those help? You can tell make to not print the command it runs by prepending the recipe line with the @ character:

code :

target:
        prog1 -i input1 input2 -o out.txt  2>&1  1>/dev/null | tee err_log
        @if [ -s err_log ]; then false ; fi
        prog2

        @[ ! -s err_log ]

Why when I write to stderr I see STDERR output on the stdout?

Hope that helps ,
I supposed only STDOUT should be visible in the terminal.

How to output the process.stderr.write to winston

By : Angelo Teste

Date : March 29 2020, 07:55 AM

it should still fix some issue Using winston loggers to write contents into the files but that works only when customlogger.error is used. If the node is outputting some reference error like below

code :

`
function formatArgs(args){
    return [util.format.apply(util.format, Array.prototype.slice.call(args))];
}
console.info = function(){
    customlogger.info.apply(customlogger, formatArgs(arguments));
};
console.warn = function(){
    customlogger.warn.apply(customlogger, formatArgs(arguments));
};`
