Windows 7 x64 Pro上的gawk 3.1.6-1即使在命令失败时也会使用system（）获取0返回代码

我正在Windows上运行gawk脚本。很长一段时间以来，我一直在WindowsXPx86上使用Gawk3.1.4，一切正常

我的环境已更改为Windows 7 x64，现在gawk 3.1.4经常失败并出现致命错误

我已经更新到最新可用的gawk 3.1.6-1（）-->致命错误消失了（yahoo），但我遇到了一个非常奇怪的行为：它无法在命令失败时获得非零返回代码

例如，我打电话

print "System return test: ";
system( "gawk --version");
myReturnCode = system( "exit 0");
print "1 returned: " myReturnCode;
myReturnCode = system( "exit 1");
print "2 returned: " myReturnCode;

结果是

System return test:

为什么

2返回：0

？？？以前的gawk版本按预期返回

由于这个原因，我所有的命令成功状态都被完全破坏了。我需要gawk中失败命令的非零返回码

有人在Windows7x64上运行gawk吗？你有类似的东西吗？有办法解决这个问题吗

UPD：为那些遇到同样问题并想尝试Cygwin的人提供一些提示 感谢@EdMorton的

gawk.exe

使用理念。是的，一般来说，它在Windows 7 x64上工作，并且

系统（“退出1”）

按预期返回

1

（请参见下面的MWE），但从

3.1.6

到Cygwin的更新并非无痛。我在想，我应该在我目前的gawk脚本windows世界中与它们作斗争，还是用Python 3重写它们

这是Cygwin从批处理（两个脚本）调用gawk的一个最简单的工作示例：

REM awkTest.cmd
@echo off
set "exeGAWK=C:\cygwin64\bin\gawk.exe"
echo exeGAWK = "%exeGAWK%"

call "%exeGAWK%" -f "test.awk" nul

及

结果是

显而易见的问题是

windows路径中的前斜杠

\

应转换为

/

无法调用Windows系统

dir

命令

下面是一个如何从Windows调用cygwin的awk的示例。在Windows中，以通常的方式将“.bash”文件后缀与“bash.exe”关联（创建“test.bash”，然后右键单击打开并在cygwin64目录下找到bash.exe），然后双击名为“test.bash”的文件，其中包含以下内容：

export HOME="/cygdrive/c/cygwin64/home/$USERNAME"
export PATH="$HOME:/usr/bin:$PATH"
. .bash_profile

# cd to the directory this script is in assuming you want it to run from there
dir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
dir="C:${dir#/cygdrive/c}"
cd "$dir" || exit 1

awk 'BEGIN {
    print "System return test: ";
    system( "gawk --version");
    myReturnCode = system( "exit 0");
    print "1 returned: " myReturnCode;
    myReturnCode = system( "exit 1");
    print "2 returned: " myReturnCode;
}'

sleep 30

它将弹出一个窗口，显示以下内容30秒：

另请参见如何执行相反的操作，即从cygwin bash脚本调用Windows命令（Excel）。

可能是个bug，idk。或者可能是你参考的那个下载文件夹说它是32位Windows的，而你是64位的。在任何情况下，Gawk3.1.6都落后于2个完整版本，大约过期5年。为什么不安装cygwin并运行gawk 5.0.1呢？gawk 5.0.1有一些错误修复和大量附加功能（并且可以按照您的要求运行）？@Ed Morton，我已经准备好更新并尝试任何更新的版本，但3.1.6是我为Windows找到的最新版本。cygwin的gawk是否可以在Windows批处理（cmd.exe）环境中的cygwin外壳外部使用？您可以从Windows批处理命令调用cygwin的bash.exe，然后从该命令调用cygwin gawk。我刚刚发布了一个答案，显示了如何调用包含直接从Windows调用cygwin gawk的cygwin bash脚本。我的答案对您不起作用吗？我不太喜欢添加这样的批处理调用，因为我不知道这样做是否正确，利弊，警告等。如果您愿意，可以在问题的末尾添加一些内容。
