PowerShell

Search Current Directory

Searchs the current path for .bat files contain the string "Monthly".

Select-String -Path "*.bat"  -SimpleMatch -Pattern "Monthly"
Select-String -Path "*.bat" "Monthly"

-SimpleMatch uses a simple match rather than a regular expression match.
In a simple match, Select-String searches the input for the text in the Pattern parameter. It doesn't interpret the value of the Pattern parameter as a regular expression statement.

Default search type is a regular expression search.

Recursive Search

The PowerShell command below searches the current directory (in this case C:\) and all subdirectories for .cs files containing text with the pattern "COMMIT" and lists the filenames.

PS C:\>Get-ChildItem -Path "*.cs" -Recurse | Select-String "COMMIT" -List | Select Path
