英文:
How can I check a folder and subfolder in PowerShell?
问题
我需要能够检查一个文件夹的内容，例如C:\Temp，如果包含图片，则运行一个计划任务，但忽略C:\Temp内的任何文件夹或其他文件类型，并将输出写入日志文件。
然后，我需要能够检查C:\temp内的子文件夹，即C:\Temp\myfolder。如果文件夹为空，则写入日志文件并不执行任何操作。否则，如果子文件夹包含图片文件，则将它们移到C:\Temp的上一级，运行一个计划任务，并写入日志文件。除了图片文件以外的所有文件类型都应该被忽略。
我已尝试过：
if((Get-ChildItem -Path C:\temp -force | Where-Object Extension -in ('.bmp','.jpg','.jpeg','.png','.tiff') | Measure-Object).Count -ne 0){
Start-ScheduledTask -TaskName Notepad
}else{
Write-Output "未找到文件。"
}
英文:
I need to be able to check the contents of a folder, for example, C:\Temp if contains pictures, run a scheduled task, but ignore any folders or other file types within C:\Temp and write the output to a log file.
I then need to be able to check a subfolder within C:\temp i.e. C:\Temp\myfolder. If folder is empty, write to log file and do nothing. Else if subfolder contains picture files, move them one level up to C:\Temp, run a scheduled task and write to a log file. All file types other than picture files should be ignored.
I have tried:
if((Get-ChildItem -Path C:\temp -force | Where-Object Extension -in ('.bmp','.jpg','.jpeg','.png','.tiff') | Measure-Object).Count -ne 0){
Start-ScheduledTask -TaskName Notepad
}else{
Write-Output "No files found."
}

我猜你想要做的是类似以下的操作：
# 将这些变量设置为您的实际环境
$sourceFolder = 'C:\Temp'
$imageTypes = '*.jpg','*.jpeg','*.png','*.bmp','*.gif','*.tiff' # 等等
$logFile = 'X:\Somewhere\mylog.log'
# 首次运行，仅处理源文件夹
$imageFiles = Get-ChildItem -Path $sourceFolder -File -Include $imageTypes
$filesFound = @($imageFiles).Count
if ($filesFound -eq 0) {
Add-Content -Path $logFile -Value "在 $sourceFolder 中未找到图像" -PassThru
}
else {
Add-Content -Path $logFile -Value "$sourceFolder 包含 $filesFound 个图像文件" -PassThru
# 运行您的定期任务
Start-ScheduledTask -TaskName Notepad -Verbose
}
# 接下来查看子文件夹中是否有图像文件
$subFolder = Join-Path -Path $sourceFolder -ChildPath 'MyFolder'
$imageFiles = Get-ChildItem -Path $subFolder -File -Include $imageTypes
$filesFound = @($imageFiles).Count
if ($filesFound -eq 0) {
Add-Content -Path $logFile -Value "在 $subFolder 中未找到图像" -PassThru
}
else {
Add-Content -Path $logFile -Value "$subFolder 包含 $filesFound 个图像文件" -PassThru
# 将文件移动到源文件夹
$imageFiles | ForEach-Object {
$_ | Move-Item -Destination $sourceFolder
}
# 运行您的定期任务
Start-ScheduledTask -TaskName Notepad -Verbose
}
请注意，这只是代码的翻译部分，不包括问题的回答。
英文:
I guess what you want to do is something like below:
# set these variables to your actual environment
$sourceFolder = 'C:\Temp'
$imageTypes = '*.jpg','*.jpeg','*.png','*.bmp','*.gif','*.tiff' # etc.
$logFile = 'X:\Somewhere\mylog.log'
# first run, just the sourcefolder
$imageFiles = Get-ChildItem -Path $sourceFolder -File -Include $imageTypes
$filesFound = @($imageFiles).Count
if ($filesFound -eq 0) {
Add-Content -Path $logFile -Value "No images found in $sourceFolder" -PassThru
}
else {
Add-Content -Path $logFile -Value "$sourceFolder contains $filesFound image files" -PassThru
# run your scheduled task
Start-ScheduledTask -TaskName Notepad -Verbose
}
# next see if there are image files in the subfolder
$subFolder = Join-Path -Path $sourceFolder -ChildPath 'MyFolder'
$imageFiles = Get-ChildItem -Path $subFolder -File -Include $imageTypes
$filesFound = @($imageFiles).Count
if ($filesFound -eq 0) {
Add-Content -Path $logFile -Value "No images found in $subFolder" -PassThru
}
else {
Add-Content -Path $logFile -Value "$subFolder contains $filesFound image files" -PassThru
# move the files to the source folder
$imageFiles| ForEach-Object {
$_ | Move-Item -Destination $sourceFolder
}
# run your scheduled task
Start-ScheduledTask -TaskName Notepad -Verbose
}
