Powershell:更新当前输出线 [英] Powershell: Update current output line

问题描述

有没有办法在powershell中更新命令输出的当前行?

is there a way to update the current line of the command output in powershell?

我知道如何写到同一行:

i know how to write to the same line:

Write-Host "hello " -NoNewLine

Write-Host "world!" -NoNewLine

但是有没有办法完成替换当前行?像这样:

but is there a way to complete replace the current line? something like:

Write-Host "hello "
Write-Host "world!" -ReplaceLine

提前谢谢！

解决方案:

Write-Host "hello " -NoNewLine
Write-Host "`rworld!"

推荐答案

使用回车键返回到行首:`r

Use carriage return to return to the start of the line: `r

查看此内容: http://ss64.com/ps/syntax-esc.html

回车的定义: http://en.wikipedia.org/wiki/回车

如果要清除一行，则需要清除一行空格.否则，您可以覆盖内容.

If you want to clear a line, that and a load of spaces. Otherwise you can overwrite stuff.

我不能在这里真正写一个示例，因为它是SO的代码字符，但请将其放在"world"字符串的开头，它应该可以工作.

I can't really write up an example here as it's SO's code character, but put it at the start of the "world" string and it should work.

希望这会有所帮助！
