RE: Powershell Question

I think you may be making this harder than it has to be. Gc the content into an 
array of [string]. -imatch against SNAPSHOT ID and then +3 from that index is 
your  volume. SO...

                $lines = gc <filename>
                for ($i = 0; $i -lt $lines.Count; $i++)
                {
                                If ($lines[$i] -imatch "^\* SNAPSHOT ID")
                                {
                                                $volline = $lines[$i + 3]
                                                ...
                                }
                }

Etc.etc.etc.

Hey Michael,

Here is some of the output of two snapped drives (could be more):

* SNAPSHOT ID = {be35a053-2fee-4aa8-aa92-6bd1b2cf5e29} ...
   - Shadow copy Set: {659a895d-1e31-4ef8-9909-ba8a21a143eb}
   - Original count of shadow copies = 2

I only know what SNAPSHOT ID to reference, and then expose if I grep this for 
the Volume name "+3 lines back". So when I job this, and put its output in a 
$JobOutput, I want to use $JobOutput for each volume that I expose to a drive 
letter. That's the part I am unsure how to do.

Thanks!

I'm going to say "yes", but I'm still not exactly sure what you are going for 
there. Look at "-match", "findstr", and "select".

Hey guys,
I am converting a shell script into a ps script and need to parse a variable 
that holds the output of an executed job.

at the cli (using unix tools) I do this:

grep -B 3 "some_string" |grep "another_string" |cut -f 5 -d " "

So basically, the output has many repetitions that have various fields 
different, when I find the one I want, I include 3 lines up and filter that 3rd 
up line to show what I want.

Is this possible using built in ps syntax?

Thanks,
jlc
