Terminate Script Execution?

I am trying to use ctrl+c to terminate a script but nothing happens. So
far I have only been able to close the command shell in order to get a
script to stop executing.

I've had similar issues with poorly-behaved objects. What's it hanging on?
There may be a way to work around this with the specific object.

it depends on what your script is doing, specifically, if you're in the
middle of a .NET Method call, CTRL-C won't take effect until the next script
line. Can you be more specific about what you're trying to do?

My script uses the get-wmiobject using the Win32_QuickFixEngineering and
Win32_OperatingSystem classes. I am reading text file that has a list of
about 300 servers and I am querying those WMI objects for each server in
a foreach loop. When I encounter a problem and I want to stop the script
from executing nothing seems to work except for closing the shell which
is a pain.

Could you show your example code?

You might be timing out when attempting to connect to a system. To determine
exactly where the problem crops up, you might also include some verbose
statements within the script so you know approximately where you are in the
code when you can't break out.

You are all missing the point. I simply want to terminate a script while
it is running no matter what it is doing. The script itself is not hung,
it just takes a long time to finish because it is reading a file and
performing a task using each line of input. Basically, I am sitting at
the shell and have run ./script.ps1. The script is running and printing
output to the screen but I want to stop it. On a Unix shell I can use
ctrl+c to cancel what the shell is currently running.

Can you terminate this script by ctrl-c?

1..1111 | %{$_; sleep 1}

And since it doesn't "just work" when PS execution is tied to an external
process (such as wmiprvse.exe in this case), I was hoping to find out where
in the cycle the script is choking. That would give me some ideas about a
good bug report for this behavior and possibly point to an interim
workaround.

Sounds like it would be more accurate to describe this as "PowerShell is not
immediately responsive to an attempt to break execution somewhere in the
script". I was under the impression that it was hanging because you said
that nothing worked - presumably meaning that control never, ever returned
to you, no matter how long you waited.

What I was really after was enough information to determine where this is
happening. If you think this is ugly and nasty compared to Unix process
handling, I have to agree with you.

Hi,

Ctrl+Z sometimes works when Ctrl+C doesn't.

I am not entirely clear on why or when.

And I don't know if it works "no matter what" a script is doing.
