问题描述
我有一个错误日志文件,该文件要复制与设置的错误字符串不匹配的所有行.因此,基本上,我正在建立一个无法识别的错误的单独文件.
I have an error log file from which want to copy all lines that DON'T match a set error strings. So basically I am building up a separate file of unrecognised errors.
我定义了所有已知的错误类型
I define all the know error types
# Define all the error types that we need to search on
$error_1 = "Start Date must be between 1995 and 9999"
$error_2 = "SYSTEM.CONTACT_TYPE"
$error_3 = "DuplicateExternalSystemIdException"
$error_4 = "From date after To date in address"
$error_5 = "Missing coded entry for provider type category record"
这就是我要读取的文件
(Get-Content $path\temp_report.log) |
Where-Object { $_ -notmatch $error_1 } |
Out-File $path\uncategorised_errors.log
(Get-Content $path\temp_report.log) |
Where-Object { $_ -notmatch $error_2 } |
Out-File $path\uncategorised_errors.log
(Get-Content $path\temp_report.log) |
Where-Object { $_ -notmatch $error_3 } |
Out-File $path\uncategorised_errors.log
我的输入文件是这样的:
My input file is like this:
15 Jul 2016 20:02:11,340 ExternalSystemId cannot be the same as an existing provider
15 Jul 2016 20:02:11,340 XXXXXXXXXXXXXXXXXXXXXXXXX
15 Jul 2016 20:02:11,340 ZZZZZZZZZZZZZZZZZZZZZZZZ
15 Jul 2016 20:02:11,340 DuplicateExternalSystemIdException
15 Jul 2016 20:02:11,340 DuplicateExternalSystemIdException
15 Jul 2016 20:02:11,340 SYSTEM.CONTACT_TYPE
当我只有3行时,我的出场完全相同:
and my out is exactly the same when I should have only 3 lines:
15 Jul 2016 20:02:11,340 ExternalSystemId cannot be the same as an existing provider
15 Jul 2016 20:02:11,340 XXXXXXXXXXXXXXXXXXXXXXXXX
15 Jul 2016 20:02:11,340 ZZZZZZZZZZZZZZZZZZZZZZZZ
推荐答案
使已知错误成为数组,使用Select-String
Make the known errors an array, use Select-String
$errors=@(
"Start Date must be between 1995 and 9999",
"SYSTEM.CONTACT_TYPE",
"DuplicateExternalSystemIdException",
"From date after To date in address",
"Missing coded entry for provider type category record"
)
Select-String -Path D:\log.txt -NotMatch -Pattern $errors
