批量排列多个网站的ping顺序? [英] Arrange the pinging of multiple website in order with batch?

问题描述

这是对我玩的游戏的服务器进行 ping 操作的批处理，以便我能够找到最适合我的服务器.

This is a batch that pings the servers of a game I play, so that I am able to find the best server for me.

有没有办法让它ping所有服务器，然后按响应从最慢到最高的顺序列出它们?

Is there a way I can have it ping all the servers then list them in order from the slowest response to the highest?

推荐答案

由于要检查/ping 的主机很多，因此顺序处理会持续很长时间，尤其是在关注Stephan 的建议使用多个回显请求并占用平均回复时间.

Since there are many hosts to check/ping, sequencial processing lasts for a quite long time, particularly when following Stephan's recommendation of using more than one echo requests and taking the average reply time.

所以我建议使用不同的方法，让 ping 请求发生在同时的进程中:

So I suggest to use a different approach and let the ping requests happen in simultaneous processes:

@title OSRS Ping Checker
@echo off
setlocal EnableExtensions DisableDelayedExpansion

rem // Define constants here:
set "_ARG=%~1" & if defined _ARG shift /1 & goto :DO_PING & ^
    rem // (jump to label `DO_LOOP` in case arguments are provided)
set "_USAWORLDS=5,6,7,13,14,15,19,20,21,22,23,24,29,30,31,32,37,38,39,40,45,46,47,48,53,54,55,56,57,61,62,69,70,74,77,78,86,117"
set "_ECHOREQUS=10" & rem // (number of echo requests to send per host)
set "_TEMPFILEB=%TEMP%\%~n0_%RANDOM%" & rem // (path and base name of temporary files)
set "_FINALFILE=%~dpn0.txt"           & rem // (path and full name of return file)

rem // Process items in sub-routine but in parallel processes:
for %%I in (%_USAWORLDS%) do (
    rem // Redirect output of every process to individual temporary file:
    > "%_TEMPFILEB%_%%~I.tmp" start /B "" cmd /C "%~f0" :DO_PING %%~I %_ECHOREQUS%
)
rem /* Wait until all temporary files are write-accessible, meaning that
rem    all the parallel processes have been completed/terminated: */
:POLL
for %%I in (%_USAWORLDS%) do (
    rem // Try appending nothing to check for write-access:
    2> nul (>> "%_TEMPFILEB%_%%~I.tmp" rem/) || (
        rem // Wait a bit to not overload the processor:
        > nul timeout /T 1 /NOBREAK
        goto :POLL
    )
)
rem // Combine all individual temporary files into one:
> nul copy /Y "%_TEMPFILEB%_*.tmp" "%_TEMPFILEB%.tmp" /B
rem // Sort data as desired (alphabetic sorting):
sort /R "%_TEMPFILEB%.tmp" /O "%_TEMPFILEB%.tmp"
rem // Create return file, write header:
> "%_FINALFILE%" echo ms      host
rem // Append sorted data to return file:
> nul copy /Y "%_FINALFILE%" + "%_TEMPFILEB%.tmp" "%_FINALFILE%" /B
rem // Clean up temporary files:
del "%_TEMPFILEB%_*.tmp" "%_TEMPFILEB%.tmp"

endlocal
exit /B


:DO_PING
    rem // Build host URL to ping, set number of echo requests to send:
    set "URL=oldschool%~1.runescape.com"
    set /A "NUM=%~2"
    rem /* Perform ping and capture last line of response, which should contain
    rem    the average reply time: */
    set "STR="
    for /F "delims=" %%P in ('2^> nul ping "%URL%" -n %NUM%') do set "STR=%%P"
    rem // Check whether last line of response contains average reply time:
    if not defined STR exit /B
    set "AVG=%STR:*Average =%"
    set "AVG=%AVG:~1%"
    if "%AVG%"=="%STR%" exit /B
    rem /* Convert average reply time to pure left-zero-padded number; the padding
    rem    is intended to simplify the later (purely alphabetic) sorting: */
    set /A "AVG=AVG"
    set "AVG=000000%AVG%"
    rem // Return average reply time together with respective host URL:
    echo %AVG:~-6%  "%URL%"
    exit /B
