[Pkg-nagios-devel] Bug#480001: nagios3: spurious dollar signs added to command_lines

Package: nagios3
Version: 3.0.1-1
Severity: normal
Tags: patch


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.
