This is maybe a dumb question, but I don't understand

I've a very dummy psc1 script myscript.psc1 on C:\ that contains an endless
loop (or what I suppose to be an endless loop...)

$i=0
while ($i -ge 0) {$i++;write-host $i}

PS C:\> $i=0
PS C:\> while ($i -ge 0) {$i++;write-host $i}
1
2
3
4
....


If I try to execute from the cmd prompt or from the PS prompt as
CMD C:\>powershell.exe .\myscript.psc1
or
PS C:\>powershell.exe .\myscript.psc1

a PS windows is open for a millisecond but it's closed immediately.
Can you please explain me what's going on?

Thanks in advance,

Nicola Attico

Try this:

PS C:\>powershell.exe -NoExit -Command .\myscript.ps1

Note that the extension should be .PS1 and *not* .PSC1. :-)

There is this gotcha when trying to run a PowerShell script from Cmd.exe.
Here is a great blog entry "Running PowerShell Scripts from Cmd.exe" by Lee
Holmes on
http://www.leeholmes.com/blog/Runnin...romCmdexe.aspx

Nicola,
PSC1 is the extension for a PowerShell console files will PS1 is the
extension for the powershell script file.

What you wrote is a script, so should be saved in a ps1 file.

PSC1 is a xml like file containing information on what snapins to load when
powershell is started (think similar to MMC console files)

Btw, the behavior you saw is actually a bug, We are not catching parse
errors in PSC1 correctly.
