国家和年份 - 最后修改日期
country & Year -Last Modified date
我试图从按 LastWriteTime 排序的文件名中拆分国家和年份，并希望按年份将剩余文件移动到存档文件夹，但只能过滤年份而不是国家名称
代码：
$sourcedir = 'C:\Users\garang\Documents\input_files\Advisory_rate'
$destdir = 'C:\Users\garang\Documents\input_files\Advisory_rate\Archive'
Get-ChildItem -File -Path $sourcedir |
Where-Object BaseName -match '_(20\d{2})_\d' |
Group-Object $Matches[1] |
ForEach-Object {
$_.Group | Sort-Object LastWriteTime -Descending |
Select-Object -Skip 1 |
Move-Item -Destination $destdir -Force
}
输出是

在上面的数据中，第 2 行将被归档，因为 2016 年意大利的最后写入时间是 12:08。
我试图通过 Group-Object {$_.Basename.Split(' ')[2]} 拆分名称，但无法在上述条件下使用
also tried:Where-Object BaseName -match ' ([a-z]+_20\d{2})_\d' | & Where-Object BaseName -match '_(20\d{2})_\d' |
$sourcedir = 'C:\Users\garang\Documents\input_files\Advisory_rate'
$destdir = 'C:\Users\garang\Documents\input_files\Advisory_rate\Archive'
Get-ChildItem -File -Path $sourcedir |
Where-Object BaseName -match ' ([a-z]+_20\d{2})_\d' |
Group-Object $Matches[1] |
ForEach-Object {
$_.Group | Sort-Object LastWriteTime -Descending |
Select-Object -Skip 1 |
Move-Item -Destination $destdir -Force
}
both conditions are tried separately gives the error message:

i got new logic into it and getting output also how fix this in the query
$Match = "[^_]+_[0-9]{4}"
$Lines = get-clipboard
$Results = $Lines | %{$_ -Match $Match | %{$Matches[0]}}
output:

这是预期的结果
好吧……举个新例子……这是四个文件……在这种情况下……需要按国家和年份分组……然后是最后修改的最大值
文件将在那里，其他文件将移动该国家/地区的存档
和年份......所以这里的第二个和第三个文件将进入档案......在示例中国家和年份重复两次的简单方法......所以较少修改的日期文件将进入那一年的档案和国家...

对不起我的错。您必须在 Group-Object
中将大括号放在 $Matches[1] 周围
$sourcedir = 'C:\Users\garang\Documents\input_files\Advisory_rate'
$destdir = 'C:\Users\garang\Documents\input_files\Advisory_rate\Archive'
Get-ChildItem -File -Path $sourcedir |
Where-Object BaseName -match ' ([a-z]+_20\d{2})_\d' |
Group-Object {$Matches[1]} |
ForEach-Object {
$_.Group | Sort-Object LastWriteTime -Descending |
Select-Object -Skip 1 |
Move-Item -Destination $destdir -Force
}
用不同的路径测试
