Handbook: Processes
Get the list of processes on a box:
box.processes
This returns a ProcessSet which behaves like an array, but also lets you do bulk actions (like "kill") on the entire set.
In the shell, "processes" by itself is a shortcut to Rush::Box.new.processes.
Processes have fields uid, pid, command, cmdline, mem, and cpu. Use filter to reduce the set to the entries you want:
box.processes.filter(:pid => ::Process.pid)
box.processes.filter(:cmdline => /ssh/)
ProcessSet acts like an array, so get more complex with a standard select:
box.processes.select { |p| p.cmdline.match(/mongrel_rails/) and p.mem > 100_000 }
Check if the process is alive, or kill it:
ff = box.processes.filter(:cmdline => /firefox/)
puts ff.alive?.inspect
ff.kill
