PowerShell - Work with counter and renaming of files
问题
以下是已经翻译好的代码部分：
$count=1000Get-ChildItem -Recurse -Include *.jpg | ForEach-Object -Process { Rename-Item -LiteralPath $_ -NewName ("PHOTO{0}_{1}_{2}" -f $script:count, $_.Directory.Name, $_.BaseName) -WhatIf }
如果你需要任何进一步的帮助，请随时告诉我。
英文:
Please help with the following situation:
There are many photos need to be renamed according to the name of directory folder, where they are located + add index at the end of each new name in format PHOTO1000_NAMEA_1, PHOTO1001_NAMEA_2, PHOTO1002_NAMEB_1, PHOTO1003_NAMEB_2, PHOTO1004_NAMEC_1, PHOTO1005_NAMEC_2, etc.
Where:
a) PHOTO1000 (1001,1002) = counter of total quantity of renamed photos;
b) _1 (_2,_3) = indexing number of concrete new name of item.
In my version of code in part a) counter did not calculate items from "1000", i++.
$count=1000Get-ChildItem -Recurse -Include *.jpg | ForEach-Object -Process { Rename-Item -LiteralPath $_ -NewName ("PHOTO_{0}_{1}{2}" -f $script:count, $_.Directory.Name,$_.Extension) -WhatIf }
Please help with correct format of code.
Thanks!!

<!-- language-all: sh -->使用两个[哈希表](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_Hash_Tables)，结合[延迟绑定脚本块](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_script_blocks#using-delay-bind-script-blocks-with-parameters)，可以实现您的任务：
$totalCount = @{ value = 0 } # 总重命名文件的计数
$countPerDir = @{ } # 每个目录名称的重命名文件计数
Get-ChildItem -Recurse -Include *.jpg |
Rename-Item -NewName {
'PHOTO_{0}{1}{2}{3}' -f ++$totalCount.value,
$.Directory.Name,
++$countPerDir[$.Directory.Name],
$.Extension
} -WhatIf
<sup>注意：上面命令中的 [`-WhatIf` 通用参数](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_commonparameters#-whatif) 用于 _预览_ 操作。一旦确定操作会按您的期望执行，请删除 `-WhatIf` 并重新执行。</sup>注意：* 通过使用 [`Rename-Item`](https://learn.microsoft.com/powershell/module/microsoft.powershell.management/rename-item)，您实际上是在原地重命名文件，而不是在单一的目标目录中；如果需要后者，请改用 [`Move-Item`](https://learn.microsoft.com/powershell/module/microsoft.powershell.management/move-item)，并使用其 `-Destination` 参数。* `$totalCount` 之所以是哈希表而不是简单的 `[int]` 变量，是因为延迟绑定脚本块在调用者的 _子_ 作用域中运行（与 `ForEach-Object` 和 `Where-Object` 脚本块不同），从子作用域引用哈希表使得能够跨作用域边界更新其条目。* `$countPerDir` 哈希表跟踪每个目录名称中已重命名的文件数。`++$countPerDir[$_.Directory.Name]` 利用了两个行为：* 对尚不存在的条目进行赋值会隐式 *创建* 该条目（使用给定的键）。* 对刚刚创建的新条目应用 `++` 实际上将其视为 `0` 并返回 `1`。
英文:
<!-- language-all: sh -->
You can use two hashtables in combination with a delay-bind script block to implement your task:
$totalCount = @{ value = 0 } # count of renamed files overall$countPerDir = @{ } # count of renamed files per directory nameGet-ChildItem -Recurse -Include *.jpg |Rename-Item -NewName {'PHOTO_{0}_{1}_{2}_{3}' -f ++$totalCount.value,$_.Directory.Name,++$countPerDir[$_.Directory.Name],$_.Extension} -WhatIf
<sup>Note: The -WhatIf common parameter in the command above previews the operation. Remove -WhatIf and re-execute once you're sure the operation will do what you want.</sup>
Note:
-
By using
Rename-Item, you're actually renaming the files in place, not in a single, flat target directory; if you want the latter, useMove-Itemwith its-Destinationparameter instead. -
The only reason
$totalCountis a hashtable rather than a simple[int]variable is that delay-bind script blocks run in a child scope of the caller (unlikeForEach-ObjectandWhere-Objectscript blocks), and referencing a hashtable from the child scope enables updating its entries across scope boundaries. -
The
$countPerDirhashtable keeps track of how any files per directory name have been renamed.++$countPerDir[$_.Directory.Name]takes advantage of two behaviors:- Assigning to an entry that didn't previously exists implicitly creates such an entry (with the given key).
- Applying
++to new entry that was just created effectively treats it like0and returns1.

我不看到你调用 $counter。你初始化它，但在 foreach 中没有再次调用它。
你有两个计数器 - 所有照片的总数，然后是基于 NAME_ 的索引，看起来是目录名称。
第一个计数器很简单 - 每次迭代后只需添加 $counter++。$index 只需基于目录 - 最简单的方法可能是根据目录分组，然后 $index++
看，我的答案
$jpgs = Get-ChildItem -Recurse -Include *.jpg | group -Property Directory$counter = 1000foreach ($group in $jpgs) {$index = 1foreach ($item in $group.Group) {rename-item -LiteralPath $item -NewName ("PHOTO{0}_{1}_{2}{3}" -f $counter, $item.Directory.Name, $index, $item.Extension)$counter++$index++}}
看，我的结果

现在只需删除 -whatif。显然。
英文:
i don't see you calling $counter. You initiate it, but don't call it again in the foreach.
You have 2 counters going - total of all photos, and then index which is based off of NAME_ which looks like the directory name.
First counter is easy - just add $counter++ after each iteration. $index just needs to be based off of directory - probably simplest way to do this is group everything off of directory, and then $index++
behold - my answer
$jpgs = Get-ChildItem -Recurse -Include *.jpg | group -Property Directory$counter = 1000foreach ($group in $jpgs) {$index = 1foreach ($item in $group.Group) {rename-item -LiteralPath $item -NewName ("PHOTO{0}_{1}_{2}{3}" -f$counter, $item.Directory.Name,$index ,$item.Extension) -WhatIf;$counter++;$index++}}
behold - my results

Now just remove -whatif. Obviously

这是我的版本，使用引用变量来计数：
[ref]$Total = 0(Get-ChildItem -Directory -Recurse) | ForEach {$_ | Get-ChildItem *.jpg -File | ForEach -Begin {[ref]$subTotal = 0} -Process {$_ | Rename-Item -NewName {'Photo_{0:d4}_{1}_{2}{3}' -f $Total.Value++ , $_.Directory.Name , $subTotal.Value++ , $_.Extension} -WhatIf}}
请注意，代码部分不被翻译。
英文:
Here's my version, using reference variables for the counters:
[ref]$Total = 0(Get-ChildItem -Directory -Recurse) | ForEach {$_ | Get-ChildItem *.jpg -File | ForEach -Begin {[ref]$subTotal = 0} -Process {$_ | Rename-Item -NewName {'Photo_{0:d4}_{1}_{2}{3}' -f $Total.Value++ , $_.Directory.Name , $subTotal.Value++ , $_.Extension} -WhatIf}}
