如何将Select-String结果输出到文件且去除行内换行

原始代码 #

$ccToSearch =@('"1008-0000108812"', "1008-0000105138", "1008-0000120485")

$ccToSearch =  $ccToSearch -split ',' | ForEach-Object { $_.Trim() }

$results5 = Select-String -Path "C:\Logs\tm1s202205*.log" -Pattern $ccToSearch 

$results5 | Out-File -FilePath "C:\Users\User\Desktop\log.txt" 

当前问题 #

提取后的日志出现行内换行，部分内容被拆分到下一行：

tm1s20220615160000.log:622:"","20220615152345","20220615152345","N","9.279340000000001e-003","0","OPEX","1008-0000108812","1008-0000750055","5760012285","Input","5555","2022","Cur
rent Cycle","Other","Direct Input","Value in Millions",""
tm1s20220615160000.log:623:"","20220615152345","20220615152345","N","1.975e-002","0","OPEX","1008-0000108812","1008-0000750055","5760012202","Input","5555","2022","Current 
Cycle","Other","Direct Input","Value in Millions",""

期望效果 #

每行完整显示，无行内换行：

tm1s20220615160000.log:622:"","20220615152345","20220615152345","N","9.279340000000001e-003","0","OPEX","1008-0000108812","1008-0000750055","5760012285","Input","5555","2022","Current Cycle","Other","Direct Input","Value in Millions",""
tm1s20220615160000.log:623:"","20220615152345","20220615152345","N","1.975e-002","0","OPEX","1008-0000108812","1008-0000750055","5760012202","Input","5555","2022","Current Cycle","Other","Direct Input","Value in Millions",""

解决方案 #

问题根源：Select-String返回的是MatchInfo对象，直接用Out-File输出时会默认截断长行；同时原始日志可能包含软换行符，导致内容被拆分。

修改后的代码 #

$ccToSearch = @('"1008-0000108812"', "1008-0000105138", "1008-0000120485")

# 原代码中-split ','是多余操作，数组本身无需拆分，直接使用即可
# $ccToSearch = $ccToSearch -split ',' | ForEach-Object { $_.Trim() }

$results5 = Select-String -Path "C:\Logs\tm1s202205*.log" -Pattern $ccToSearch 

# 提取完整行内容，移除行内软换行符，指定宽度避免自动截断
$results5.Line | ForEach-Object { $_ -replace '\r?\n', '' } | Out-File -FilePath "C:\Users\User\Desktop\log.txt" -Width 2000

关键说明 #

• -replace '\r?\n', ''：移除行内的软换行符（兼容Windows和Unix换行格式）
• -Width 2000：指定输出宽度，避免PowerShell自动截断长行，可根据日志实际长度调整数值
• 移除了原代码中多余的数组拆分步骤，因为$ccToSearch本身就是字符串数组，直接传入Select-String即可
