Vista Tutorial - Possible to Read only Selected lines from multiple files into anotherfile deleting source files when processed?

My experience with powershell is measured in hours, but I've got to
say I'm STOKED at what I've seen so far!
I've used my so far limited skills in an attempt to do the following
without success:

I have a folder containing zero to many files named like *.in their
contents are roughly the following format:

Header
dataline xxxxxxxxxxxxxxxxxxxxxxxxxxUseMexxxxxxxxxxxxxxxxxxxxxxxxxxxxx
dataline xxxxxxxxxxxxxxxxxxxxxxxxxxUseMexxxxxxxxxxxxxxxxxxxxxxxxxxxxx
EOF

I need to read only the data lines from each file into a single file
(data.out) and delete each .in file as it has been processed.
I have gotten pretty close filtering by $_.Length -gt 6, but getting
it into a single output file and then deleting the source file eludes
me.

Is this possible and if so how?

Your help is greatly appreciated.

> I need to read only the data lines from each file into a single fileGive this a try (change your paths accordingly):

get-childitem c:\demo2\tmp -recurse *.in|foreach-object{
select-string $_ -pattern "^dataline"|foreach-object{
add-content "c:\demo2\tmp\data.out" $_.tostring().split(":")[3]
}
remove-item $_.fullname -whatif
}

Welcome to PowerShell! ;-)

It may take a more than a few hours to get your head around things, but
its worth the ride!

Thanks for your response - intriguing!
I couldn't get it to actually put the detail line into the file
data.out until I removed '.split(":")[3]' - what does that do?

Thanks again for your help,
Joe

Hmmmm... I'm using the v2 CTP so perhaps select-string is doing
something different for me.

..split is a method where the string passed is split-up into elements by
the character passed to it (":" in this case). "[3]" simply means that
once the string is split, get me the 4th element (4th because PowerShell
counts starting at 0 in this case).
