我的数据文件a.alm如下：

2018-05-19  00:26:00,551 [LUNSC1  ] D_TA204_GT1_DV_AL             CFN              LARM      D_TA204_GT1_Reglerfel                  
2018-05-19  00:28:01,049 [LUNSC1  ] D_TA204_GT41_DV_AL            CFN              LARM      D_TA204_GT41_Reglerfel                 
2018-05-19  00:28:01,049 [LUNSC1  ] D_TA204_GT31_DV_AL            CFN              LARM      D_TA204_GT31_Reglerfel                 
2018-05-19  00:28:01,049 [LUNSC1  ] D_TA204_GT21_DV_AL            CFN              LARM      D_TA204_GT21_Reglerfel                 
2018-05-19  00:35:19,627 [LUNSC1  ] U_TA364_GT11_LARM             CFN              LARM      U_TA364_GT11_LARM                      
2018-05-19  00:39:56,135 [LUNSC1  ] U_TA364_GT11_LARM             CFN              LARM      U_TA364_GT11_LARM                      
2018-05-19  00:47:12,612 [LUNSC1  ] U_KB6_GT11_DV_AL              CFN              LARM      U-KB6-GT11 Avvikelselarm

我想将令牌5和8​​提取到另一个文件中。在我的代码中，我读取文件的内容并使用split函数循环。

$alarmList = @(Get-Content -Path '.\A.ALM') | foreach {
    $test = $_ -split ' '
    Write-Host $test[6]" "$test[9]
} | Out-File -FilePath '.\Output.txt'

输出仅给我第一个令牌。而且我无法理解如何正确地将其打印到文件中。尝试将Write-Host替换为File-Output，但收效不佳。

D_TA204_GT1_DV_AL 
D_TA204_GT41_DV_AL 
D_TA204_GT31_DV_AL 
D_TA204_GT21_DV_AL 
U_TA364_GT11_LARM 
U_TA364_GT11_LARM 
U_KB6_GT11_DV_AL 
U_FF415_GT46_L_AL 
U_KB6_GT11_DV_AL 
U_KB6_GT11_DV_AL 
U_KB6_GT11_DV_AL

我之前在命令行中使用此脚本对此进行了管理。

FOR /F "tokens=5" %%i in (A.alm) do echo %%i >> data.txt

但是我想在PowerShell中进行处理并将其通过管道传输，以能够使用我已经拥有的计数发生次数的脚本中的数据。

(Select-String -Path '.\data.txt' -Pattern '[^ ]+' -AllMatches).Matches.Value |
    Group-Object -NoElement |
    ConvertTo-Csv -Delimiter "`t" -NoTypeInformation |
    Out-File -FilePath '.\Statistics.csv'

这很好，我了解得最多。

    $alarmList = @(Get-Content -Path '.\A.ALM') | foreach { 
    $token = $_ -split ' +'
    [PSCustomObject]@{
         date = $token[0]
         time = $token[1]
         H2   = $token[2]
         H3   = $token[3]
         H4   = $token[4]
         H5   = $token[5]
         H6   = $token[6]
         H7   = $token[7]
         H8   = $token[8]
    }
}
$alarmList | Group H4 -NoElement | Select Name,Count | Out-Gridview

  • 使用for /f
    • 复制此行为

只是为了演示-split ' +'运算符基于正则表达式的结果：

-split

简短的a.alm输出：

(Get-Content -Path '.\A.ALM') | foreach { 
    $token = $_ -split ' +'
    for ($i=0;$i -le 8;$i++){
        "token[{0}]={1}" -f $i,$token[$i]
    }
}

要让$ alarmList包含所有这些列：

token[0]=2018-05-19
token[1]=00:47:12,612
token[2]=[LUNSC1
token[3]=]
token[4]=U_KB6_GT11_DV_AL
token[5]=CFN
token[6]=LARM
token[7]=U-KB6-GT11
token[8]=Avvikelselarm

$alarmList = @(Get-Content -Path '.\A.ALM') | foreach { 
    $token = $_ -split ' +'
    [PSCustomObject]@{
         date = $token[0]
         time = $token[1]
         H2   = $token[2]
         H3   = $token[3]
         H4   = $token[4]
         H5   = $token[5]
         H6   = $token[6]
         H7   = $token[7]
         H8   = $token[8]
    }
}
$alarmList | ft -auto

当然，您可以进一步玩它：

date       time         H2      H3 H4                 H5  H6   H7                     H8
----       ----         --      -- --                 --  --   --                     --

# $alarmList | Out-Gridview
# $alarmList | Export-csv '.\Output.csv' -NoTypeInformation
$alarmList | Group H4 -NoElement | Select Name,Count

答案 1 :(得分：1)

您可以使用Select-Object和-Index参数选择要提取的行的索引，最后将其存储到Output.txt文件中。

$file = Get-Content .\A.ALM
$file | Select-Object -Index 6,9 | Out-File -FilePath '.\Output.txt'
