  for (j in h) if (h[j]>1) print "dup host "j
}' /etc/hosts

NAME
avahi.hosts - avahi-daemon static host name file SYNOPSIS
/etc/avahi/hosts DESCRIPTION
/etc/avahi/hosts is a file which may be used to define static host name to IP address mappings for multicast DNS. This is especially useful when publishing DNS-SD services on behalf of other hosts. See avahi.service(5) for more information. The file format is similar to the one of /etc/hosts: on each line an IP address and the corresponding host name. The host names should be in FQDN form, i.e. with appended .local suffix. AUTHORS
