For example, running the Get-ChildItem command to examine filesystem objects results in the permissions of each object being returned in an attribute called “Mode”. When using Select-Object, Format-List, or Format-Table, it is possible to use hash tables to dynamically rename attributes or to calculate synthetically-generated attributes on the fly. Here is a more practical example in which the hash table is used literally as a dictionary lookup table, translating Korean words (rendered in Hangul) to English. It is somewhat reminiscent of the ability to use Unicode strings to define variable names in Apple’s programming language, Swift. I don’t know how useful this particularly is, but it amuses me. Keep in mind that key names are simply strings, and since PowerShell strings by default use UTF-16 encoding, we are squarely in the world of Unicode, which can, in turn, include Emoji. In that case, the arguments in square brackets are passed as an array index rather than a key. I should note here, however, that the syntax changes behavior when the hash table is defined as an ordered hash table (as in the way in which I have redefined $myHashTable2 in these examples). There is, however, a syntax for constructing a hash table of type if that is needed: PS C:\> $myHashTable2 = "One Hundred"ġ0000 Ten Thousand Accessing Hash Table ValuesĪccessing the values of hash table entries by means of the keys is pretty straightforward, and multiple syntaxes are provided for doing so. It should be noted that order is not necessarily preserved in a hash table: PS C:\> $myHashTable2 Here is what the resulting hash table looks like: PS C:\> $myHashTableĪlternatively, we could have populated the hash table at the time that we created it via the following syntax: $myHashTable2 = "One Hundred" Here is the PowerShell syntax for initializing an empty hash table object: $myHashTable = add elements to the hash table quite easily via several different mechanisms. Readily accessing or modifying values by way of their corresponding keys. $DesktopOutput | Out-File \\Some_Server\Share\Results\Results.A hash table is an array of key/value pairs, along with accompanying functions for $DocumentOutput | Out-File \\Some_Server\Share\Results\Results.txt -Append $DocumentOutput = "Documents " -f ($DesktopSize.sum / 1GB) "GB" ![]() # This converts the Documents folder size to GB with 1 decimal place and outputs the result. $DesktopSize = (Get-ChildItem $env:USERPROFILE\Desktop -recurse | Measure-Object -property length -sum) # This collects the user running the script's Desktop folder size. $DocumentsSize = (Get-ChildItem $env:USERPROFILE\Documents -recurse | Measure-Object -property length -sum) Here's what I came up with: # This collects the user running the script's Documents folder size. I figure PowerShell should be able to tell me this information, and I have a script that kinda-sorta does what I want it to, but it's not robust enough. Hey guys I've been asked to find out from all the workstations in my environment, how much space users are using on their Desktop and Documents folders. ![]()
