我在 test1.txt 中有以下行

我喜歡在數字之后但在單詞（incr 或 manual）之前獲取唯一名稱。所以我使用了下面的代碼。
$backupLogLines = @(Get-Content C:\scripts\test1.txt) -match "incr|full|manual"
$planTable = @{}
foreach ($line in $backupLogLines)
{
$metadataParts = $line -csplit "incr|full|manual"
# first string is host name,
# second string is discarded,
# ... and the rest are backup plans
$clientHostName,$null,$backupPlans = -split $metadataParts[0]
if(-not $planTable.Contains($clientHostName)){
# Create new array containing the backup plans for the current
$planTable[$clientHostName] = @($backupPlans)
}
else {
$planTable[$clientHostName] = $backupPlans
}
}
但 $backupPlans 也可能有重復項。如何避免這樣 hashTable 只有獨特的計劃？
uj5u.com熱心網友回復：
您可以重寫現有代碼以使用嵌套哈希表，如下所示：
$backupLogLines = @(Get-Content C:\scripts\test1.txt) -match "incr|full|manual"
$planTable = @{}
foreach ($line in $backupLogLines)
{
$metadataParts = $line -csplit "incr|full|manual"
# first string is host name,
# second string is discarded,
# ... and the rest are backup plans
$clientHostName,$null,$backupPlans = -split $metadataParts[0]
if(-not $planTable.Contains($clientHostName)){
# Create new inner hashtable to hold observed backup plans
$planTable[$clientHostName] = @{}
}
foreach($plan in $backupPlans){
$planTable[$clientHostName][$plan] = $true
}
}
如果對同$plan一個客戶端多次觀察到相同的情況，腳本現在將簡單地更新/設定已經存在的同一個表條目。
最后將內部值轉換為陣列：
foreach($key in @($planTable.PSBase.Keys)){
$planTable[$key] = @($planTable[$key].PSBase.Keys)
}
