How would I run '/usr/bin/java -jar "/path/to/jenkins.war" &' with OSProcess? Specifically I want to know the process number of the java child process. I unsuccessfully tried: * PipeableOSProcess command: '/usr/bin/java -jar "/path/to/jenkins.war" &', which successfully launches java, but I don't know its pid because the returned process is the completed parent "sh" that launched it * PipeableOSProcess command: '/usr/bin/java -jar "/path/to/jenkins.war"' (without ampersand), which also launches successfully, and leaves the parent "sh" process running as well (not as clean), but I still don't know the java pid I then succeeded with: p := PipeableOSProcess command: '/usr/bin/java -jar "/path/to/jenkins.war" & { echo $! ; }'. p output lines first. But this seems convoluted and I'm assuming there must be a simpler way. What is the best way to do this? I.e.: * launch a long running child process * without keeping the sh process open * accessing the pid of the child Thanks, Sean -- View this message in context: http://forum.world.st/Running-in-background-with-OSProcess-tp4615534.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
