[问题求助] [已解决]求修改PowerShell正则表达式

param([string]$file);		#修改前的文件
$file1 = [io.fileinfo]$file;
$file2 = [io.path]::Combine($file1.DirectoryName, $file1.BaseName) + '_整理.h';# 新的路径

-replace'(\[[^]]*\])|(?<=[|!]) +','$1' 会把"-delims:| "或"-delims:, "或"-delims:[ "替换为"-delims:|"或"-delims:,"或"-delims:["

#修改以下PowerShell 当其中出现"-delims:| "或"-delims:, "或"-delims:[ "  等只要-delims: 出现则不替换
#例如
MSTR * -delims:,&i,&j=<1*>&k	则替换变为 MSTR * -delims:, &i,&j=<1*>&k
MSTR * -delims:, &i,&j=<1*>&k	则不替换不做任务操作
MSTR * -delims:%a% &i,&j=<1*>&k	则不替换不做任务操作
#我尝试
-replace'(\[[^]]*\])|(?<=[|!])(?<!-delims:) +','$1'
-replace'delims:(\[|,|\|)','delims:$1 '
-replace 'delims:(.)(?=\S)(?!:)','delims:$1 ' 但遇MSTR * -delims:%a% 又会被分割成 -delims:% a%

(Get-Content $file2) | ForEach-Object {
    if ($_ -notmatch "-delims:\s*\S") {
        $_ -replace "-delims:", "-delims: "
    } else {
        $_
    }
} | Set-Content $file2




(Get-Content $file -ReadCount 0)-replace'(\[[^]]*\])|(?<=[|!]) +','$1'-replace'ENVI ','set '-replace'ENVI\^','set^'-replace'envi$','set$'-replace'envi~','set~'-replace'envi\.','set.'-replace'envi<','set<'-replace'envi-ret','set-ret'|Set-Content -encoding Unicode $file2
#替换后行尾多出一行CRLF
(Get-Content -Raw -Path $file2 -Encoding Unicode) -replace "`r`n", "`n"| Set-Content -Path $file2 -Encoding Unicode
复制代码

[IO.File]::WriteAllText($file2,([IO.File]::ReadAllText($file, [Text.Encoding]::Unicode) -replace 'ENVI(\^|\$|~|\.|\<|-ret| )','set$1'-replace'\r\n',"`n"),(New-Object System.Text.UnicodeEncoding $fale));
