This PowerShell blog post will show how to use PowerShell to search for a string or pattern inside any file with PowerShell.
In the following example, I have a test file that contains three lines of text. Using PowerShell select-string I can scan the entire file for a specific string.
Below is my text file that contains three lines of text.
At the most basic form, I can use the command as follow and print the result to the screen.
Select-String -Path .\file.txt -Pattern "myname"
The following cmdlets will search the text file for the string myname. It also saves the results to a variable and print the line number the match is found, the actual line and the details of the result.
$search = Select-String -Path .\file.txt -Pattern "myname" $search.LineNumber $search.Line $search.Matches
