How to crontab screen with script inside and a "don't run it if it's already running" check?

[Dwayne Henderson]

Any comments on this though?

*/10 * * * * lockf -t 0 /home/anonymous/.myscript.lock
/usr/local/bin/screen -dm /home/anonymous/.rvm/rubies/
ruby-1.9.3-p0/bin/ruby /home/anonymous/myscript.rb

Thanks for the help!
