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

Copy and then Rename files via PowerShell

Scenario:  You want to collect logs from various servers and place the copied logs into a single directory.  Due to the log names being the same on each server, we want avoid overwriting existing logs. We also want to know the server from where each log was copied from.

Solution:  The following will copy the IMAP logs from 4 servers into 1 local directory. Each file when copied to the directory will be renamed by prefixing the file with the server name.  It will also add the counter to the end of the file.

$Servers = "ExSvr1","ExSvr2","ExSvr3","ExSvr4"
$servers | %{$File = Get-ChildItem -Path "\$_c$Program FilesMicrosoftExchange ServerV15LoggingIMAP4" -Recurse;$i=1;Foreach ($f in $File) {Copy-Item $f.FullName ("C:TempIMAPPOP$_" + $f.BaseName + $i +".log");$i++}}
#End
