# OUTPUTS

Get-Variable returns a System.Management.Automation variable object for each variable that it gets. The object type depends on the variable.

# NOTES

This cmdlet does not manage environment variables. To manage environment variables, you can use the environment variable provider.

# EXAMPLE 1

C:\PS>get-variable m*

# Description
-----------
This command displays variables with names that begin with the letter "m". The value of the variables is also displayed.

# EXAMPLE 2

C:\PS>get-variable m* -valueonly

# Description
-----------
This command displays only the values of the variables with names that begin with the letter "m".

# EXAMPLE 3

C:\PS>get-variable -include M*,P* | sort-object name

# Description
-----------
This command gets information about the variables that begin with either the letter "M" or the letter "P". The results are piped to the Sort-Object cmdlet, sorted by name, and displayed.

# EXAMPLE 4

C:\PS>get-variable -scope 0

C:\PS> compare-object (get-variable -scope 0) (get-variable -scope 1)

# Description
-----------
The first command gets only the variables that are defined in the local scope. It is equivalent to "get-variable -scope local" and can be abbreviated as "gv -s 0".

The second command uses the Compare-Object cmdlet to find the variables that are defined in the parent scope (Scope 1) but are visible only in the local scope (Scope 0).
