The use of printf is necessary so you can nicely format the output as 
mail.
echo does not easily support linebreaks and such. You could force them
of course by using quoting ^M into the output, but that might pose other
unforeseen problems.

As someone who has never really used printf (at least not outside C), any 
reason you can't use echo? Seems to work:

/usr/local/nagios/libexec# printf "tes\t"
tes

/usr/local/nagios/libexec# echo "tes\t"
tes\t

Should work similar to this:

FILE=`mktemp /tmp/nagios_XXXXXX` && echo "my_text_with_backshashes" > 
$FILE && cat $FILE | mail -s "mytext" recipient at example.com ; rm $FILE

(and there's probably a way to do this without temp files and my "useless 
use of cat", too ;)

Cheers,

Carsten

Subject: [Nagios-users] Printf issues with $output$


I've seen a few questions on this subject but have yet to find the
solution, so apologies if I'm going over old ground here.

I'm monitoring some Windows server disks and the resulting output is
along the lines of:

'c:\ - total: 16.92 Gb - used: 11.92 Gb (70%) - free 5.00 Gb (30%)', but
printf is cutting off everything after the 'c:' in the email alerts as
it is processing the backslash as an exit request. Any ideas how to get
around this??

Cheers,

Ian
