Hiya,
In the definition of a "command" object such as:
define command{
command_name my_test
command_line echo '$xxx'
}
If the "command_line" contains an odd number of "$'s", then
nagios adds an extra one.
For instance, in the above example, the command becomes
echo '$xxx'$
And the output of a service based on that "command" becomes
"$xxx$" instead "$xxx".
It can have more severe impacts than that.
Fix:
