使用 Powershell 从包含特定单词的 CSV 中删除一行？

Question

Here are some sample rows from my CSV file.

"ComputerName","Name","Publisher","InstallDate","EstimatedSize","Version","Wow6432Node"
"pcnumber1","Service Pack 1 for Microsoft Office 2013 (KB2850036) 32-Bit Edition","Microsoft P",,"0",,"True"
"pcnumber1","CCleaner","Piriform",,"0","5.01",

The original script pulls a large amount of information about installed software from a specified computer and outputs it into a CSV format. I want to take that CSV file and remove all rows that have "Microsoft P" in them. I have found how to remove specific words from a string, how to find and replace, etc. I am having a hard time finding this specific function though.

Answer 1

您可以使用 Where-Object 导入、选择所有不包含“Microsoft P”的元素，然后导出：

Import-Csv test.csv | where {$_.Publisher -ne "Microsoft P"} | Export-Csv New.csv -notypeinfo

Answer 2

You can use FINDSTR as Mark Setchell suggests. Just indicate that it is a literal search string with /C .

FINDSTR /V /C:"Microsoft P" SomeFile.CSV > NewFile.CSV

Answer 3

Or if you want a PowerShell solution you can ignore the fact that it's a CSV and just treat it like a text file. Then you could:

Get-Content C:\Path\To\File.csv | Where{$_ -notmatch "Microsoft P"} | Out-File C:\Path\To\NewFile.csv

Answer 4

您可以使用多个字符串

FINDSTR /V /C:"Microsoft P" /C:"Linux R" /C:"Whatever W" SomeFile.CSV > NewFile.CSV
