Hey all
I would like to use Pd to start and stop several instances of a certain command. I need to catch the stdout of the commands in Pd, so I can monitor their status. Also, I want to be able to kill them individually.
I tried to achieve that with [ggee/shell], but there are some culprits.
When I launch the command directly in [shell] like this:
[command ( | [shell]
I get the command's stdout on the left outlet of [shell], but I don't know of a reliable way to send a SIGHUP signal to command.
On the other, I can launch a wrapper script that sends command to the background and returns its PID:
#!/bin/sh command & echo $!
and in Pd, I do:
[./wrapper.sh ( | [shell]
and the left outlet of [shell] gives me the PID of the command which allows me to reliably kill that instance later. However, this way [shell] doesn't output the command's stdout.
Is there a way to have my cake and eat it, too?
