如何更快地批量运行powershell命令？

Question

您可以在命令提示符中创建彩色文本，但是当它运行时它真的很慢。有没有办法让它更快？

我的代码：

@echo off
cls
powershell write-host -fore Yellow -back Red "Merry" -NoNewLine
powershell write-host -fore Red -back Yellow "Christmas" -NoNewLine
powershell write-host -fore Yellow -back Red "To" -NoNewLine
powershell write-host -fore Red -back Yellow "Everyone" -NoNewLine
powershell write-host -fore Yellow -back Red "In" -NoNewLine
powershell write-host -fore Red -back Yellow "2020!" -NoNewLine

Answer 1

Powershell 是一个外部程序，每次使用时都必须加载。所以只用一次：

@echo off
cls
powershell write-host -fore Yellow -back Red "Merry" -NoNewLine; ^
write-host -fore Red -back Yellow "Christmas" -NoNewLine;^
write-host -fore Yellow -back Red "To" -NoNewLine;^
write-host -fore Red -back Yellow "Everyone" -NoNewLine;^
write-host -fore Yellow -back Red "In" -NoNewLine;^
write-host -fore Red -back Yellow "2020!" -NoNewLine

与之前的 6 次相比，Powershell 只需加载一次。

所述^ 在所述线的端部是一个“行继续”，所以实际上，这仅仅是一个长的（逻辑）线，分裂成数个（物理的）线readabilty：

powershell write-host -fore Yellow -back Red "Merry" -NoNewLine;write-host -fore Red -back Yellow "Christmas" -NoNewLine;write-host -fore Yellow -back Red "To" -NoNewLine;write-host -fore Red -back Yellow "Everyone" -NoNewLine;write-host -fore Yellow -back Red "In" -NoNewLine;write-host -fore Red -back Yellow "2020!" -NoNewLine

请注意，cmd具有最大行长（约 8k 个字符），这限制了此方法。
