在windows上为stderr更改文本输出颜色

我最近发现了一篇文章，它提供了一种解决方案，让stderr输出的文本为Linux（bash）使用不同的颜色

他们创建了以下bash脚本

#!/bin/bash
{ $* 2>&1>&3|sed 's,.*,\x1B[33m&\x1B[0m,'>&2;} 3>&1

这会导致输出在来自stderr时打印黄色文本。stdout仍然打印相同的颜色

脚本保存在名为color的$PATH目录中。这允许我使用make或scon运行脚本，它将以黄色显示来自stderr的所有文本。（将33m改为31m可使文字变为红色）

这对于在编译时查找错误非常有用

是否有类似的脚本可用于Windows cmd shell

---

注意：如果有帮助的话，我已经在我的windows计算机上安装了sed。

关于windows的cmd.exe下对ANSI转义码的支持，请参阅。将重定向逻辑转换为cmd.exe语法后，我准备了以下

color.bat

文件：

@Echo Off
(((%* 1>&3) 2>&1) | "c:\Program Files (x86)\GnuWin32\bin\sed.exe" "s,.*,\x1B[33m&\x1B[0m," 1>&2) 3>&1

不幸的是，流混合在一起（在某些行中，来自stdout和stderr的字符在一行中混合在一起）。也许这种行为取决于使用的sed.exe版本，所以请尝试一下

如果这不起作用，请考虑使用最小安装。我测试了你的

color.sh

脚本，我能够启动一个.bat文件，它在不混合流的情况下正常工作。我使用的语法是：

./color.sh cmd /c test.bat

---

我设计了一种使用纯批处理命令获得等效解决方案的方法，即不使用Ansi、不使用sed.exe等，只使用findstr：

any_command 2>&1 1>&3 | findstr /N /A:4E "^"

在这种情况下，stderr中的整行不使用不同的颜色，而只使用findstr提供的行号，但该行号应足以满足规定的要求。我将很快编写一个小的辅助.exe程序，用另一种颜色显示整个stderr行。

我将

color

重命名为

co

，因为

color

是一个Windows命令，我将其扩展为：

谢谢，我现在不在我的计算机上，但我会尝试一下并让您知道。谢谢非常有用，因为我在路径中使用了sed，所以我不必指定完整路径，只留下@Echo Off（（（（（*1>&3）2>&1）|“sed.exe”s、.*、\x1B[31m&\x1B[0m，“1>&2）3>&1在我的Win7上，此命令确实会为行着色，但只输出stderr，stdout未显示。我最终将脚本命名为hilite（突出显示的拼写错误），因为我也遇到了颜色问题。不过，我非常喜欢该脚本。：）
