前言

近期在项目上遇到一个比较严重的问题，在更新SharePoint文档库中文件时，由于开启了文档库历史版本，导致每一次更新会增加一个版本，导致空间严重不足，下面将使用power shell命令删除历史版本

命令 

#Config Variables
$SiteURL = "SharePoint站点地址"
$ListName="文档库名称"
$VersionsToKeep = 1 #所保留的版本个数
#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Credentials (Get-Credential)
#Get the Context
$Ctx= Get-PnPContext
#Get All Items from the List - Exclude 'Folder' List Items
$ListItems = Get-PnPListItem -List $ListName -PageSize 2000 | Where {$_.FileSystemObjectType -eq "File"}
ForEach ($Item in $ListItems)
{#Get File Versions$File = $Item.File$Versions = $File.Versions$Ctx.Load($File)$Ctx.Load($Versions)$Ctx.ExecuteQuery()Write-host -f Yellow "Scanning File:"$File.Name$VersionsCount = $Versions.Count$VersionsToDelete = $VersionsCount - $VersionsToKeepIf($VersionsToDelete -gt 0){write-host -f Cyan "`t Total Number of Versions of the File:" $VersionsCount#Delete versionsFor($i=0; $i -lt $VersionsToDelete; $i++){write-host -f Cyan "`t Deleting Version:" $Versions[0].VersionLabel$Versions[0].DeleteObject()}$Ctx.ExecuteQuery()Write-Host -f Green "`t Version History is cleaned for the File:"$File.Name}
}
