Kill via Cron...

[mcoyles]

Morning all - on FreeBSD 7.1 (for various reasons - don't ask)
Am attempting to run the following via cron but it keeps erroring out:

kill -9 `ps ax | grep backup | grep -v grep | awk '{print $1}'` && kill -9
`ps ax | grep dump | grep -v grep | awk '{print $1}'`


Error: 

usage: kill [-s signal_name] pid ...
       kill -l [exit_status]
       kill -signal_name pid ...
       kill -signal_number pid ...

Works OK from commandline - what do I need to change to make this cronable??


Cheers
