Stopping netstat.exe after one display?

[swiftie]

"netstat /?" says:

"interval Redisplays selected statistics, pausing interval seconds
between each display. Press CTRL+C to stop redisplaying
statistics. If omitted, netstat will print the current
configuration information once."

On my system, it keeps running displaying connections as they are established. What is that "If omitted" referring to?

Is there a way to get a snapshot without having to use Ctrl+C to quit netstat.exe?

So by running netstat on its own, the command will display your current TCP/IP network connections and protocol statistics ONCE.

By running

netstat [COLOR="Red"]<SomePositiveNonzeroIntegerValueHere>[/COLOR]

you are telling the netstat command to output your network connections and protocol statistics indefinitely. Once the command has finished displaying all statistics, it'll wait <SomePositiveNonzeroIntegerValueHere> seconds before repeating the netstat command again.

So running netstat 4 is kind of like running the batch script

@echo off
:top
netstat
timeout 4 >NUL
goto :top

Is there a way to get a snapshot without having to use Ctrl+C to quit netstat.exe?

I'm not so sure what you mean by snapshot?

The bit that I'm struggling with is the "once". If I run "netstat -a -b" then I get a list of connections, but then netstat keeps running, adding new connections to the end of the list.

So, in order for netstat to terminate, I always have to Ctrl+C it.

It just seems a little odd, having to use Ctrl+C regardless of the parameters used. It's no big deal though, just a curiosity.

Does the same for me on my Win 8 Pro X64 system and Win 7 Pro X64 system.

I don't understand. I'm not sure what I'm supposed to be answering here.

Are you saying that the output of the command netstat -a -b is infinity ongoing? It isn't. With a stopwatch in hand, for me, it takes just over 30 seconds at its quickest and 2 minutes at its longest for the command netstat -a -b to complete. Depending on how connection involved your machine is, the Net Status command can take a while to execute.


The title of this thread questions how one would go about halting the execution of a command after one cmd screen full of display. To answer that, you'd pipe to more.
E.g.

netstat | more

Guess I didn't wait long enough. Took 39 seconds for me.
