I would like to retrieve text file logs off network servers (all in the same application path on remote servers), parse the text for the last 20 lines of the file and put that all in to one local csv file.

I need a starting point.

Thanks.

I think you want: GET-CONTENT, and Export-CSV at a minimum
http://technet.microsoft.com/en-us/library/ee176843.aspx

I think this will do it... Just add: "| Export-csv MyFile.csv" on the end.

[PS] C:\>  foreach ($server in ("Server01","Sevrer02")) {dir \\$server\c$\Logs\*.log | foreach-object {$_ | get-content | select-object -last 20}}

one similar one i've used in the past.
$comps = get-content c:\temp\servers.txt
$filepath = '\c$\path\to\file.txt'

@(foreach($comp in $comps){
(get-content \\$comp$filepath)[-20 .. -1]
}) | export-csv -notype c:\temp\output.csv

Looks like Dave came up with the same answer basically, just a little more elegant :)
Mine is meant as a single line straight from the command line, and his is meant to be saved in a .PS1 file and executed.

Enjoy. I just started playing with Powershell in December.

These are both perfect answers.  The first one is just a bit easier to follow for a newbie.

Can one of you guys add the code on how to get only the most recent log file from that folder/location?

I appreciate it.

Thanks.
