Hey!

Just been tryi= ng to figure out the same thing. This is what I came up with:

*/10 *= * * * lockf -t 0 /home/anonymous/.myscript.rb.lock /usr/local/bin/screen -= d -m -S myscript /home/anonymous/.rvm/rubies/ruby-1.9.3-p0/bin/ruby /home/a= nonymous/myscript.rb

Uses lockf to make sure the script isn't already running.

I have, for the first time, installed ruby using rvm.
I run my backups via crontab, calling a bash script that runs a ruby
script. However, that script now tell me that it doesn't know about rub=
y.
So I entered two lines in the bash script:

  RVM=3D/usr/local/rvm/scripts/rvm
  test -e $RVM && source $RVM

and it runs OK; but it seems to me that this is not the way it should be
done. Is it?
Cron runs as sh shell. it doesn't read bashrc or profile.d files like rvm.sh. so it will not know where to find ruby that's installe= d in rvm.

for one of our project this is how we've been running things:

=20
Note : We recommend to add cron job for checking the available network conn=
ections. Add following into the crontab :=20
    */5 * * * * bash -c 'source /etc/profile.d/rvm.sh && /usr/b=
in/env ruby /usr/local/rvm/gems/ruby-1.9.3-p125/bin/ispunity monitor'
also have a look at this

https://= rvm.io/integration/cron/
Newer RVMs also have a script called `rvm_shell`.

=A0 $RVM_INSTALL_LOCATION/bin/rvm_shell 1.9.3 -c 'ispuni= ty monitor'

(or similar) should work.
If you have a system level RVM, it should be rather easy.<= /div>
