Get-ChildItem Adding a Exclude filter for Assembly.*.dll but include Assembly.Some.*.dll

I have a requirement where I want to exclude all the assemblies which are having pattern

Assembly.*.dll

but want to include all the assemblies having pattern

Assembly.Some.*.dll

from the same location through Get-ChildItem.

I want to achieve this functionality in a single line of script.

Solution

  • You could use the -or operator inside a Where-Object filter:

    Get-ChildItem -Filter *.dll |Where-Object {
  $_.Name -like 'Assembly.Some.*.dll' -or $_.Name -notlike 'Assembly.*.dll'
}

    Since any assembly with a name like Assembly.Some.Namespace.dll will already return true on the first condition, the second condition won't be tested
