我想添加3個重試到下面的代碼,從USB複製目錄到一臺機器,並在複製後檢查兩個目錄是否相等。如果3次重試後它們不相等,我想恢復以前的配置文件夾。重試powershell循環
我有如何實現重試
[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
if (Test-Path "D:\Upgrade\CONFIG") { $src_dir = "D:\Upgrade\CONFIG" }
elseif (Test-Path "F:\Upgrade\CONFIG") { $src_dir = "F:\Upgrade\CONFIG" }
elseif (Test-Path "G:\Upgrade\CONFIG") { $src_dir = "G:\Upgrade\CONFIG" }
else { $src_dir = "E:\Upgrade\CONFIG" }
$dest_dir = "C:\TEST\CONFIG"
$date_str = Get-Date -UFormat %d%b%Y
$time_str = Get-Date -UFormat %H%M%S
$archive_dir = "$dest_dir" + "." + "$date_str" + "." + "$time_str"
if (Test-Path $src_dir) { Ren "$dest_dir" "$archive_dir" -verbose; Copy-Item "$src_dir" "$dest_dir" -recurse -verbose }
else { [System.Windows.Forms.MessageBox]::Show("$src_dir found, could not complete !!!") }
$currentConfig = Get-ChildItem -Recurse $dest_dir | Where-Object { -not $_.PsIsContainer }
# NEED HELP WITH ADDING RETRIES HERE
$currentConfig | ForEach-Object {
# Check if the file, from $dest_dir, exists with the same path under $src_dir
If (Test-Path ($_.FullName.Replace($dest_dir, $src_dir))) {
# Compare the contents of the two files...
If (Compare-Object (Get-Content $_.FullName) (Get-Content $_.FullName.Replace($dest_dir, $src_dir))) {
# List the paths of the files containing diffs
$_.FullName
$_.FullName.Replace($dest_dir, $src_dir)
}
}
}
所以在我的例子中,當目錄不相等時,我會遞減計數器,如果它們相等,則會中斷計數。是或者我需要另一個if語句嗎? – user1984300
你基本上會運行循環,完成你想要完成的工作,如果沒有正確完成,請將數字減1。如果工作完成到你滿意,你可以使用break來早日退出循環。 –
