Answer 1

Knowing how to use CMD scripting deftly is great, but using PowerShell is even better. Here's one way to do it:

$revision = (( gc .\svninfo.txt | ? { $_.StartsWith( 'Revision: ' ) } ) -split ' ')[1]

What's going on?

$revision is a variable

gc is Get-Content, aka type. Each line in the file becomes a string in a sequence (pipeline).

? is Where-Object. It filters the objects in a pipeline based on a condition.

{} delimits a script block

$_ is the current object in the pipeline.

-split invokes String.Split() in .NET, giving you an array of objects

[1] indexes in to the array
