I have a rack/ruby application on a server. I run it as follows:
nohup rackup -o 0.0.0.0 -p 1234 &
In the output of "top" command it appears as simply "ruby"
PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND 98421 my_user123 3 20 0 140M 29576K select 0:29 0.01% ruby
How can I adjust its name in the "top"? What if I run 5 such web apps, how would I distinguish which is which if they're all "ruby"?
