Hi, I run this Ruby + Sequel script inside a screen that records data
from
this live stream 24/7. But it tends to core dump every once in a while,
and
since I run it in a screen (so it’s easy to check in on), I can’t really
scroll up to catch the error whenever it happens.
So how do I crontab the screen with the Ruby script inside it? Has to be
with a “don’t run it if it’s already running” check to avoid fatal
consequences. So far I have:
I am not 100% sure what you want to achieve. But it seems to me that
it would be easier to wrap your Ruby script in something else that
restarts the script if it crashes. Like
#!/usr/bin/dash
no cores
ulimit -c 0
while :; do
/home/anonymous/.rvm/rubies/ruby-1.9.3-p0/bin/ruby
/home/anonymous/myscript.rb
done
