For this example, the function only exists in the PowerShell session. When the PowerShell session is closed, the function is deleted. The function is created on the PowerShell command line.

The Function command uses the name Search-Help. Press Enter to begin adding statements to the function. After the closing bracket is added, you're returned to a PowerShell prompt. The function contains two commands. The Select-String command in the function uses the Path and Pattern parameters. To run the function, type Search-Help. The function's Select-String command displays the output in the PowerShell console. This example searches for a string in a Windows event log.

The MaxEvents parameter gets the 50 most recent events from the log. Select-String uses the InputObject parameter. The Recurse parameter includes the subdirectories. The objects are sent down the pipeline to Select-String. Select-String uses the Pattern parameter and specifies the string Microsoft. The CaseSensitive parameter is used to match the exact case of the string.

Dependent upon your permissions, you might see Access denied messages in the output. Select-String uses the Path parameter to specify the Command. The Pattern parameter specifies Get and Set as the search pattern. The NotMatch parameter excludes Get and Set from the results. The Pattern parameter specifies Get-Computer as the search pattern.

The Context parameter outputs the two lines before the first pattern match and three lines after the last pattern match. This example shows how the AllMatches parameter finds each pattern match in a line of text. By default, Select-String only finds the first occurrence of a pattern in a line of text.

This example uses object properties that are found with the Get-Member cmdlet. The Get-ChildItem cmdlet uses the Path parameter. Select-String uses the Pattern parameter to search each file for the string PowerShell. There's a line that contains two occurrences of the string PowerShell.

Matches property lists the first occurrence of the pattern PowerShell on each line. Length property counts the first occurrence of the pattern PowerShell on each line. AllMatches finds each occurrence of the pattern PowerShell on each line. Length property increases because for each line, every occurrence of the pattern PowerShell is counted.

The ToString result of the piped object isn't the same rich string representation produced by PowerShell's formatting system. So, you may need to pipe the objects to Out-String first. Piping to Out-String converts the formatted output into a single multi-line string object. This means that when Select-String finds a match it outputs the whole multiline string.

Piping to Out-String -String converts the formatted output into a multipel single-line string objects. This means that when Select-String finds a match it outputs only the matching line. Indicates that the cmdlet searches for more than one match in each line of text. Without this parameter, Select-String finds only the first match in each line of text.

How can I use Windows PowerShell to find the path to folders that have names that match a specific pattern? Use the Get-ChildItem cmdlet and the —Filter parameter with a pattern that matches the name, and then specify the —Directory parameter.

Sometimes we need to search in notes such as quick. Fortunately there is scripting on our side and, specially, Powershell scripting to aid in this usually very time consuming activity. Let's consider a directory, ' C:Temp ' with many text files created.

Each of the files has random text data inside. If you want to export that all to a file instead of on the screen, then simply pipe it into an Out-File cmdlet.

For example:. Get-Childitem includes two additional parameters, -Include and —Exclude: their functions are pretty simple and they can be very useful when searching for some specific file types. The -Include parameter says, 'Show me only these files in the search', and -Exclude says, 'Keep that stuff out of my way.

We could now use this same command fo example to show only the Word documents that we can access and all the files that include ' software ' word in the filename. The above command will pull everything with the letters, software , in it, including folder titles.
