从输出中删除空行? [英] Remove blank lines from output?

问题描述

当我运行这个命令时，它返回带有很多空行的输出.

When I run this command, it returns the output with lots of blank lines.

Get-Host | Select Name, Version | Format-List

我尝试使用 ExpandProperty 但它仍然在输出的末尾留下一个空行，有没有办法删除最后一个空行?

I tried using ExpandProperty but it still leaves me with one blank line at the end of the output, is there a way to remove the last blank line?

Get-Host | Select -ExpandProperty Name, Version | Format-List 

推荐答案

如果你真的需要Format-List提供的格式，那么你可以使用Out-String和 Trim() 去除空行:

If you really need the format that Format-List provides, then you can use Out-String and Trim() to get rid of empty lines:

Get-Host | Select Name,Version | Format-List | Out-String | ForEach-Object { $_.Trim() }

但是，根据您的需要，使用 CSV 或 JSON 格式进行进一步处理可能更容易(请参阅 ConvertTo-Json 或 ConvertTo-Csv).

But, depending on your needs, it's probably easier to just use CSV or the JSON format for further processing (see ConvertTo-Json or ConvertTo-Csv).
