Powershell脚本可在显示时动态替换控制台中的文本

Question

Is it possible to use powershell scripting to scan all console output in a powershell window, before it is outputted, and replace certain words with other words so that the altered output is displayed in the console?

My use case is that if I replace null with an ANSI colored null, the special chars are escaped on display. I want to unescape them on display to show in color.

For example; \\pset null '[91m[0m'

displays null in the console as \\x1B[91m\\x1B[0m

So I would wish replace all instances of this with a delicious ANSI colored null everywhere in the console window.

Thanks in advance

I don't know about scanning output, but you can always "-replace" anything that might generate output:

eg

{write-host "Hey, this is stuff"} -replace "stuff","things"

[System.Reflection.Assembly]::LoadFile("C:\\windows\\assembly\\GAC_64\\System.Data\\2.0.0.0__b77a5c561934e089\\System.Data.dll") -replace "4.0.0.0","3.1415"
