Question

我试图仅从报告的第一行中删除引号。报告的其余部分，报价都很好。我尝试了这个，但它删除了第一行之后的所有内容：

(gc daily_report_yyyymmdd.csv -First 1) |
    % {$_ -replace '"', ""} |
    Out-File daily_report_yyyymmdd.csv -Fo -En Ascii

Answer 1

您正在选择一行，然后将其写回同一文件，基本上用该行覆盖整个文件。结果：其他所有内容都被删除。

我并不太关心你在这里想要达到的目标。如果您确定它始终是第一行，您可以试试这个。

$File = gc daily_report_yyyymmdd.csv
$File[1] -replace '"', ""
$File | Out-File daily_report_yyyymmdd.csv -Fo -En Ascii

不会为可扩展性留下很大空间

Answer 2

我在PowerShell中将DOS转换为UNIX，它处理了我的CR问题：

$csvdata = [io.file]::ReadAllText('in.csv') | % {$_ -replace "`r",""}
[io.file]::WriteAllLines('out.csv', $csvdata)

我只想删除第一行的引号
