#SCRIPTCASE EDIOR VISUAL STUDIO CODE#
If you’re thinking about going this route, consider reading my blog post Using Pester to Test PowerShell Code in Other Cultures. You could be creating a different problem-especially if you’re potentially working with other cultures. PS C:\> $Features = 'SQLENGINE', 'SSMS', 'ADV_SSMS'ĭo you think that you’ll outsmart the case-sensitivity issues in PowerShell by using the ToUpper or ToLower method to convert strings to a specific case before performing comparison operations on them? Not so fast. MethodsĪs you can see in the following example, methods such as contains and replace are case sensitive, whereas the contains and replace operators are not case sensitive. For more detailed information abouit JSON, see this Hey, Scripting Guy! Blog post: JSON Is the New XML.
JSON is case sensitive, but the custom objects that are created when using the ConvertFrom-Json cmdlet are case insensitive. PS C:\> $hashtable.Add('ComputerName', 'PC01') PS C:\> $hashtable = New-Object -TypeName Notice in the following example, I can add the two keys that failed in the previous example: + FullyQualifiedErrorId : ArgumentExceptionĪ special case-sensitive hash table can be created though. + CategoryInfo : NotSpecified: (:), MethodInvocationException PS C:\> $hashtable.Add('computername', 'pc01')Įxception calling "Add" with "2" argument(s): "Item has already been added. PS C:\> $hashtable = C:\> $hashtable.Add('ComputerName', 'PC01') Notice that I can’t add ComputerName and computername to the hash table in the following example because, by default, the keys are the same: Hash tables are case insensitive by default.

For more detailed information about this topic and to learn how to work around this, see the following Hey, Scripting Guy! Blog post: PowerShell Workflows: Restrictions. PS C:\> 'PowerShell', 'powershell', 'POWERSHELL' | Sort-Object -CaseSensitiveĬase-insensitive switch statements are not supported in PowerShell workflows. PS C:\> 'PowerShell', 'powershell', 'POWERSHELL' | Sort-Object By default, sorting with Sort-Object is case insensitive. Specifying this parameter when using Sort-Object indicates that the sort should be case sensitive. One example is the Sort-Object cmdlet, which has a CaseSensitive parameter. Some cmdlets have parameters to control case sensitivity. $objectGUID = $($)Įnabled = (-not($($user.GetDirectoryEntry().InvokeGet('AccountDisabled')))) $stringSID = (New-Object -TypeName ($($),0)).Value $Search = "(&(objectCategory=person)(objectClass=user)(samaccountname=$user))" If the case for samaccountname is changed inside of pscustomobject, the samaccountname will not be returned. An example is shown in the following function. When you’re using PowerShell to access information from a technology that’s outside of PowerShell, such as from Active Directory with ADSI, the rules for case sensitivity in PowerShell no longer apply. Specifying the #region or #endregion tags in anything other than lower-case letters breaks the ability to collapse that portion of the code.

Regions were introduced in Windows PowerShell 3.0. To learn more about escape characters, see the about_Escape_Characters Help topic in PowerShell or view the online version: about_Escape_Characters. The special meaning of these characters doesn’t occur when an upper-case character is specified, for example:
Operatorsīy default, the comparison operators that you’ll commonly see used with PowerShell are case insensitive. The answer to whether PowerShell is case sensitive is, “It depends.” In general, PowerShell is not case sensitive, but there are a number of caveats to case sensitivity, some of which are intentional, and some that are unexpected. He blogs at and can be found on twitter few months ago I wrote a blog post called Some Cases of Unexpected Case Sensitivity in PowerShell, and I thought I would expand on that topic a bit here as a sequel to that original post.Įverything is case insensitive in PowerShell, right? Well, that’s what we’re normally taught, but it’s actually not quite that simple. Mike is also the leader and co-founder of the Mississippi PowerShell User Group. He is the winner of the advanced category in the 2013 PowerShell Scripting Games. Mike has written guest blog posts for the Hey, Scripting Guy! Blog, PowerShell Magazine, and. He is a co-author of Windows PowerShell TFM 4 th Edition, and is a contributing author of a chapter in the PowerShell Deep Dives book. Mike F Robbins is a Microsoft MVP for Windows PowerShell and a SAPIEN Technologies MVP. Welcome back guest blogger, Mike Robbins. Microsoft Scripting Guy, Ed Wilson, is here.
