Use PowerShell to search through multiple log files for specific text and export the results

Scenario:  You have multiple log/txt files you need to search through for specific text.  You would like to export/dump the text into another file.

Solution:  Run the following PowerShell Script.  Note the pattern contains the word you are looking for.  Unlike the “FIND” function in the command prompt, the PowerShell search does not require an exact case sensitive match.

#Look for any lines that has a text Pattern of "Fail" on it.
$1 = Get-ChildItem c:Temp*.log | Select-String -Pattern "Fail"

#For each line, export it to a csv.
$1 | Select line | Export-csv C:temptestline.csv
