![]() However, this inconsistency was declared to be by design - see GitHub issue #17514. While with only a single argument - the filter script block ( ) does not, due to the array wrapper. ![]() Note how using (.) around the arguments is now a syntactic necessity. value property access is attempted on that collection, which, however, still works as intended, courtesy of the PowerShell feature known as member-access enumeration. The new tab called File Hashes is Hashtab Features Calculate and display hash values from over two dozen popular hashing algorithms like MD5, SHA1, SHA2, RipeMD, HAVAL and Whirlpool. To use, just right-click on any file and select Properties. Where() always returns an array-like collection, even if only a single value is matched - see this answer for details. HashTab provides OS extensions to calculate file hashes. Where() call to stop filtering once the first match has been found, if you expect or are only interested in one match: $.( It will often not matter in practice, but you can optimize a. Where() method (as used in your own solution) is a more efficient - and more flexible - alternative to filtering a collection via the Where-Object cmdlet. value property value.įor collections already in memory, the intrinsic. name property value is 'ADDR', which then allows you to return its. That hash table is going to be built like this: First, you use Select-Object because, well, thats the command. In your case, you need to find the array element whose. You could create a hash table to do just that. Leaving aside that the identifier ADDR is a property value rather than a property / key name in your case, you fundamentally cannot use key-based index notation ( ) on an array - that generally only works on a (single) hashtable (or, more generally, dictionary). value property (an easy way to tell is that the display output's column headers are name and value, whereas with hashtables they would be Name and Value). (b) whose elements are (presumably) instances that each have a a. (a) an array, as your diagnostic output with. To complement your own effective solution:Įven though your display output of $.containers.env looks like the representation of a (single) hashtable, the value is actually:
