RE: /usr/bin/printf: %,: invalid directive

I ran into a problem similar to this with disk space percentages.  If
the return from your command has a '%' in it, printf doesn't handle it
correctly unless it's a double '%%'.  I started using 'echo -e' instead
of 'printf', however someone on this list suggested re-formating the
string to printf:

command[host-notify-by-email]=/usr/bin/printf "***** NetSaint
*****\n\nNotification Type: %s\nHost:%s\nState: %s\nAddress: %s\nInfo:
%s\n\nDate/Time: %s\n", $NOTIFICATIONTYPE$, $HOSTNAME$, $HOSTSTATE$,
$HOSTADDRESS$, $OUTPUT$, $DATETIME$ | /bin/mail -s 'Host$HOSTSTATE$
alert for $HOSTNAME$!' $CONTACTEMAIL$

Thanks ! Must be ping then, since it returns the % packet drop.

So do you know if STDER can be piped out to /dev/null in the email
command?

I guess I can try it ;)
