Running an external process asynchronously

Hi all,
All the question is in the title;

I need to run an external process from my powershell script asynchronously,
I want powershell to continue my script execution as soon as this process is
started.

Any idea?

Thanks in advance

can use Start-Process like so:

foo.ps1
--------
echo "Before"
Start-Process csc.exe -arg '/?' -noshellexecute
echo "!!!!! After !!!!!"

Many thanks guys,
Indeed I just realized that the thing I need to call asynchronously is a
powershell function of my own.

An example :
#The function
function Synchronise(computername)
{
....
}


#The script
Synchronise(PC1)
Synchronise(PC2)
Synchronise(LINUX1)
Synchronise(MAC1)


My function Synchronise is called several times and I need to run
asynchronously. This function is used to synchronise a set of files and
folders on computers and it's called several times because we synchronise
several computers.

I would like to see the script to continue once the synchronisation is
launched.

Thanks in advance for your help.

I can't think of another easier way for you to attempt what you want.

Thanks for quick answer Marco,
No the function doesn't return any result, it is just a "run and forget"
function.

And I can't make the inside aynchronous as the actions performed by the
function must be sequential. So the whole function must be aynschronous.

you willing/wanting to try out, and we will go from there:

#1: v1: Use Jim's background jobs.
#2: v1/v2 CTP: Use Keith's PSCX.
#3: v2 CTP: Use *-PSJobs

If in a prod environment, and you can't go installing 3rd party
PowerShell add-ons, then it seems #1 is your option. It is just some
PowerShell scripts that use existing functionality provided by
PowerShell v1.

Marco

Thanks Marco,
I've just taken a look at the jim's background jobs and I think this is what
I need.

Thanks for your help.
