Does anyone know if there is a way to read .gz files with Powershell?  I need to look for specific text in a large group of .gz log files.  Thanks for any ideas or help.

Well, how many hoops are you willing go through?  I'm not aware of any .gz unzipper for Windows other than Cygwin: http://www.cygwin.org/cygwin/ .

So you may have to have PowerShell cally Cygwin to unzip the files...

May want to check this out for ideas: http://wannemacher.us/?p=225

He's using the .NET GZipStream class: http://msdn.microsoft.com/en-us/library/system.io.compression.gzipstream.aspx

You can also look at the PowerShell Community extensions

This Module contains Cmdlets like :

read-Arichive and Write-Gzip (write-Tar etc.)

I wrote a function for this exact purpose and figured I'd share it here:

It will read the contents of the GZip file and write it into the shell as one System.String object per line of text.  I combine it with a filter to gather log data for my network team.
