.SH DESCRIPTION
.B nagios-exists
will query a Nagios installation via a MK Livestatus socket to determine
whether a host or a host/service combination exists. If it exists, it exits
with 0; otherwise it exits with 1. Under normal circumstances, it produces no
output; it's intended to be used in scripts.
.P
The path to the socket defaults to /usr/local/nagios/var/rw/live. It can be
overriden by setting MK_LIVESTATUS_SOCKET in the script's environment.
