Can anyone explain what is going on here? If, in a terminal, I run sleep 10 and then hit Ctrl-C it interrupts the sleep. However, if I use an exec node to run the sleep and kill it with msg.kill set to SIGINT then the exec node shows killed immediately, but the sleep does not complete until it has …

You are right, having investigated further I can see that the exec node starts a shell to run the command, so looking at the active processes I see 27958 0.0 0.0 2600 724 ? SN 11:31 0:00 /bin/sh -c sleep 30 27959 0.0 0.0 8380 696 ? SN 11:31 0:00 sleep 30 and…

Is this windows? Perhaps it a similar situation where a child process is spawned & you need to send a negative PID (mentioned in a similar topic just recently regarding VLC) In windows task manager I see... [image] EDIT tried minus pid - didnt kill sleep.exe on windows. Also noted, windows gene…

Hey Colin, Could this perhaps explain it? Not sure... Bart

Try this - it grabs the PID number using the status node and stuffs it into a flow variable. The second flow formats a kill command and tuns it. [Screen Shot 2020-06-08 at 6.26.15 AM] [{"id":"9aa9f124.4c468","type":"debug","z":"5b02c2f0.56c2a4","name":"","active":true,"tosidebar":true,"console":f…

[image] Colin: run the command in spawn mode What are the implications of that?

@Steve-Mcl It just means any output from the command comes 'on the fly' and if you need to know when the command has completed then you have to use the output from o/p 3 to indicate that. For the actual command I am trying to run that is not an issue. A corollary is that the optional timeout sett…

I am a bit confused now, looking at the info for the exec node it says that in the default mode it uses the exec system call, but the docs for that on linux say that this replaces the running process with the new one, keeping the same pid, so that doesn't make sense.
