Describes how to use wildcard characters in Windows PowerShell.

Wildcard characters represent one or many characters. You can use them
to create word patterns in commands. For example, to get all the files
in the C:\Techdocs directory that have a .ppt file name extension, type:

Get-ChildItem c:\techdocs\*.ppt

In this case, the asterisk (*) wildcard character represents any characters
that appear before the .ppt file name extension.

Windows PowerShell supports the following wildcard characters.

Wildcard Description Example Match No match
-------- ------------------ -------- ----------------- --------
* Matches zero or a* A, ag, Apple banana
more characters

? Matches exactly ?n an, in, on ran
one character in
the specified

[ ] Matches a range [a-l]ook book, cook, look took
of characters

[ ] Matches specified [bc]ook book, cook hook

You can include multiple wildcard characters in the same word pattern.
For example, to find text files whose names begin with the letters "a"
through "l", type:

Get-ChildItem c:\techdocs\[a-l]*.txt

Many cmdlets accept wildcard characters in parameter values. The
Help topic for each cmdlet describes which parameters, if any, permit
wildcard characters. For parameters in which wildcard characters are
accepted, their use is case-insensitive.

You can also use wildcard characters in commands and script blocks, such as
to create a word pattern that represents property values. For example, the
following command gets services in which the ServiceType property value
includes "Interactive".

Get-Service | Where-Object {$_.ServiceType -like "*Interactive*"}

In the following example, wildcard characters are used to find property values
in the conditions of an If statement. In this command, if the Description of a
restore point includes "PowerShell", the command adds the value of the CreationTime
property of the restore point to a log file.

$p = Get-ComputerRestorePoint
foreach ($point in $p)
{if ($point.description -like "*PowerShell*")
{add-content -path C:\TechDocs\RestoreLog.txt "$($point.CreationTime)"}}
