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 ' +'

将连续的定界符（默认为空格）计为一个
for /f 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

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'
