I'm working on a script that transfers files between directories. I've got a flag that if invoked, PowerShell deletes everything in the destination directories before adding the new content.

However, the script is executing faster than remove-item can clear the directories. How do I pause the script and have it wait for remove-item to finish?

Start-sleep works somewhat, but if there's enough items to delete, it starts the script back up before remove-items is done. (Experienced that already.)

Re: Waiting for commands to execute in scripts
Here is an idea.
$command contains the scriptBlock that gets child items depending on your objective:
a) remove all items (directories and files), or
b) remove all files only
Then the scriptBlock's return is compared to check for the presence of qualifying child items.
*Note that $command is not executed when it is declared.

# get all items (directories and files) in $destination recursively to remove
$command = {Get-ChildItem $destination -recurse -force}

# get all files only in $destination recursively to remove
$command = {Get-ChildItem $destination -recurse -force | Where-Object {!$_.PSIsConainer}}

# execute while qualifying child items exists
While (!!(& $command))
# get all qualifying child items and remove them
& $command | Remove-Item -force
