bash - Make stdin and stderr visible

Question

is there a way to make stdin and stderr visible in unix bash/zsh/whatever?

Maybe turn the stderr output to red or something like that.

It is always a pain if you are figuring out why you can't parse the output from command x. This often drives me crazy. Then I do the 2> thing but at this point 30 minutes are already gone...

Answer 1

我通常只是做

command | grep '.*'

我已将 $GREP_COLORS 设置为

ms=01;32:mc=01;32:sl=:cx=:fn=35:ln=32:bn=33:se=36

这意味着标准输出为绿色，而标准错误保持黑色（或白色）。

您可以使用stderred自动着色stderr。它是一个拦截某些流函数的共享库，因此适用于任何使用这些函数写入终端的程序。
