SHORT DESCRIPTION
Describes how to access items from the working location in PowerShell.
LONG DESCRIPTION
The current working location is the default location to which commands
point. In other words, this is the location that PowerShell uses if you do
not supply an explicit path to the item or location that is affected by the
command. In most cases, the current working location is a drive accessed
through the PowerShell FileSystem provider and, in some cases, a directory
on that drive. For example, you might set your current working location to
the following location:
C:\Program Files\Windows PowerShell
As a result, all commands are processed from this location unless another
path is explicitly provided.
PowerShell maintains the current working location for each drive even when
the drive is not the current drive. This allows you to access items from
the current working location by referring only to the drive of another
location. For example, suppose that your current working location is
C:\Windows. Now, suppose you use the following command to change your
current working location to the HKLM: drive:
Set-Location HKLM:
Although your current location is now the registry drive, you can still
access items in the C:\Windows directory simply by using the C: drive, as
shown in the following example:
Get-ChildItem C:
PowerShell remembers that your current working location for that drive is
the Windows directory, so it retrieves items from that directory. The
results would be the same if you ran the following command:
Get-ChildItem C:\Windows
In PowerShell, you can use the Get-Location command to determine the
current working location, and you can use the Set-Location command to set
the current working location. For example, the following command sets the
current working location to the Windows directory of the C: drive:
Set-Location c:\windows
After you set the current working location, you can still access items from
other drives simply by including the drive name (followed by a colon) in
the command, as shown in the following example:
Get-ChildItem HKLM:\software
The example command retrieves a list of items in the Software container of
the HKEY Local Machine hive in the registry.
PowerShell also allows you to use special characters to represent the
current working location and its parent location. To represent the current
working location, use a single period. To represent the parent of the
current working location, use two periods. For example, the following
specifies the System subdirectory in the current working location:
Get-ChildItem .\system
If the current working location is C:\Windows, this command returns a list
of all the items in C:\Windows\System. However, if you use two periods, the
parent directory of the current working directory is used, as shown in the
following example:
Get-ChildItem ..\"program files"
In this case, PowerShell treats the two periods as the C: drive, so the
command retrieves all the items in the C:\Program Files directory.
A path beginning with a slash identifies a path from the root of the
current drive. For example, if your current working location is C:\Program
Files\PowerShell, the root of your drive is C. Therefore, the following
command lists all items in the C:\Windows directory:
Get-ChildItem \windows
If you do not specify a path beginning with a drive name, slash, or period
when supplying the name of a container or item, the container or item is
assumed to be located in the current working location. For example, if your
current working location is C:\Windows, the following command returns all
the items in the C:\Windows\System directory:
Get-ChildItem system
If you specify a file name rather than a directory name, PowerShell returns
details about that file (assuming that file is located in the current
working location).
