Help with a cron entry please

[Feek]

Hi folks,

I need to run two commands via cron. The first one needs to run once an hour, on the hour and that should be easy enough.

0 * * * *

The second one isn't quite so simple though - It needs to run every ten minutes, at xx:10, xx:20, xx:30, xx:40 and xx:50

So it's not every ten minutes continually as it won't run on the hour at xx:00.

I don't have a linux box in front of me to test this on, I'll be doing it at the remote site (still haven't been able to sort out remote access) so need to get it right first time.

Can anyone assist please?

Thanks.

Pretty sure that's right, I don't have a Linux box in front of me either though so perhaps someone else could verify.

I just put in cron checker in google and got a few... but here's one:

Given the CRON job starting at 2015-10-04 06:52:44 (now), it would run:
