Question

我正在使用Powershell脚本来自动执行一些长期运行的部署任务。

我正在使用

$scripts = Get-ChildItem -r -Path server-deploy | select -expand fullname

得到一个看起来像这样的数组

D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-10.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-20.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-30.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-40.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-50.ps1

如果需求发生变化，我在其中留下了一些“漏洞”以添加额外的脚本。这些脚本将始终被命名为“ install-someword-int.ps1”，并且顺序由int确定。

我知道Get-ChildItem已经按照正确的顺序对它们进行了排序，但是我希望能够创建一个始终可以对它们进行排序的函数，因此如果我需要添加脚本（例如install-builder-15） .ps1，我知道它将在10点之后和20点之前运行。作为一个好的托管人，我并不固有地相信Get-ChildItem总是以正确的顺序返回它们。

我正在寻找对$ scripts进行排序的正确方法，或者使用某种for循环来迭代数组，但始终以正确的顺序进行。

install-builder-10.ps1                                                                                                                 
install-builder-20.ps1                                                                                                                 
install-builder-30.ps1                                                                                                                 
install-builder-4.ps1                                                                                                                  
install-builder-5.ps1

如果我运行Sort-Object @{e={$_ -match ".*install-.*-(?<number>\d+).ps1"; $matches.number}}，我会看到它们的顺序相同。我希望

install-builder-4.ps1                                                                                                                  
install-builder-5.ps1 
install-builder-10.ps1                                                                                                                 
install-builder-20.ps1                                                                                                                 
install-builder-30.ps1

如果您只想对字符串末尾的整数进行排序，则可以使用Sort-Object对其进行排序，如下所示：

$paths = "D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-30.ps1",
         "D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-sortofbuilder-20.ps1",
         "D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-10.ps1",
         "D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-20.ps1",
         "D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-50.ps1",
         "D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-notbuilder-10.ps1",
         "D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-15.ps1"

$paths | Sort-Object @{e={$_ -match ".*install-.*-(?<number>\d+).ps1" | Out-Null; [int]$matches.number}}

哪个输出如下：

D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-10.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-notbuilder-10.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-15.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-sortofbuilder-20.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-20.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-30.ps1
D:\BitBucket\CI\serverdeploy\builder\server-deploy\install-builder-50.ps1

这是“按计算值排序”概念的另一个变体。这会将结尾数字转换为[int]，然后再对它们进行排序。 [咧嘴]

$FakeFileList = @(
    [System.IO.FileInfo]'install-builder-10.ps1'
    [System.IO.FileInfo]'install-builder-20.ps1'
    [System.IO.FileInfo]'install-builder-30.ps1'
    [System.IO.FileInfo]'install-builder-4.ps1'
    [System.IO.FileInfo]'install-builder-5.ps1'
    )

$FakeFileList |
    Sort-Object {[int]$_.BaseName.Split('-')[-1]}

输出...

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
