Updating path string
For example, you can use Set-Item Property to set the value of the Is Read Only property of a file object to $True.You also use Set-Item Property to create and change registry values and data.The $True automatic variable represents a value of TRUE. To see all of the properties and methods of a File Info object, pipe the file to the Get-Member cmdlet. Core\Registry:: HKEY_LOCAL_MACHINE\software PSChild Name : contosocompany PSDrive : HKLM PSProvider : Microsoft. Core\Registry No Of Locations : 2 No Of Employees : 823 PS C:\ Get-Item Property -Path "HKLM:\Software\Contoso Company" PSPath : Microsoft. Core\Registry:: HKEY_LOCAL_MACHINE\software\contosocompany PSParent Path : Microsoft. It creates the No Of Employees entry in the Contoso Company key in HKLM\Software key and sets its value to 823. The second command uses the Get-Item Property cmdlet to see the new registry entry.For more information, see about_Automatic_Variables. For example, type Get-Item Property -Path "HKLM:\Software\My Company" PSPath : Microsoft. Core\Registry:: HKEY_LOCAL_MACHINE\software\contosocompany PSParent Path : Microsoft. Because registry entries are considered to be properties of the registry keys, which are items, you use Set-Item Property to create registry entries, and to establish and change their values. If you use the Get-Item or Get-Child Item cmdlets, the entries do not appear because they are properties of a key, not items or child items.The Set-Item Property cmdlet changes the value of the property of the specified item.You can use the cmdlet to establish or change the properties of items.You can type the content in the command or send content through the pipeline to Set-Content.
In the future it would be nice to have a good Q/A for this.
I can now very easily add folders to PATH variable or remove them from it, without having to edit any file or worry about messing up the formatting of the variable. =) System It's WIN key on keyboard Pause/Break (WIN Break).
This is extremely helpful and speeding up process of setting new environmental variables on Win8 because there you have to click through several windows in modern ui (Yeah.
On systems with an implicit root directory, absolute paths begin with a path separator or with a tilde expression (“”).
Where a device must be specified, you can do that yourself—introducing a system dependency—or allow the string object to add a default device.For example, you can add a new registry entry to a key and establish or change its value.
