I have an action that I need to perform on a regular basis, and the
means of determining if the update should be done requires an SQL

variable, but how do I provide the feedback to cfengine based on the
return code as to whether the action should be performed or not...
Any ideas appreciated?
Here is an example that may help
control:
# This returns 1 if there is a /home partation, 0 if not
ret_home = ( ExecResult(/bin/sh -c "df -l | grep -E '^/dev' | awk
'{print $NF}' | grep -c '^/home'"))
classes:
# Here I use strcmp to check if ret_home is a 1 or 0
# if it is a 1, HomePart is defined
HomePart = ( Strcmp("1","${ret_home}") )
disks:
# Check /home for free space. if less the 25%, define FullHome
HomePart::
/home/ freespace=25% inform=false define=FullHome force=true
shellcommands:
# If FullHome is defined, echo a little warning message that
# is then emailed to me
FullHome::
"/bin/echo 'WARNING: /home is very low on disk space!'"
You can skip the whole disk part and run a shell command based
on what Strcmp returns.
HomePart = ( Strcmp("1","${ret_home}") )
