How to Filter Multiple File Types with Get-ChildItem in PowerShell

Try this:

gci . *.* -rec | where { ! $_.PSIsContainer }

Assuming fossil is a command used with your version control system, based on skimming through the users guide.

You will need to pass each $_.FullName into the fossil command one at a time in order for it to successfully process the file for you. You would do this using the foreach command. So it would look like:

Get-ChildItem -Recurse | foreach {fossil add $_.FullName}

You need to think in terms that each time you add the | it is passing all of the object properties to the next process or command. In your instance $_.FullName is the specific object you want to work with in the next segment. Calling the command for your version control system it has to be passed in one at a time, you do this using the foreach command.
