删除与数组匹配的行

Question

我有一个完整的行文件,我想删除任何与数组中的字符串匹配的行,使用PowerShell:

$stringsiDoNotWant = @("admin", "student")

$content = gc file.txt

但

$content = $content -notcontains $StringsiDoNotWant

不起作用:我在变量中仍然有"admin"和"student" $content.

Answer 1

试试这个:

(Get-Content file.txt) | Where {$_ -notmatch 'admin|student'} | Out-File somefile.txt

要么

$content = Get-Content file.txt
$content = $content | Where {$_ -notmatch 'admin|student'}
