            [-R number] hostname [server]
       -a is equivalent to -v -t *
       -c specifies query class for non-IN data
       -C compares SOA records on authoritative nameservers
       -d is equivalent to -v
       -l lists all hosts in a domain, using AXFR
       -i IP6.INT reverse lookups
       -N changes the number of dots allowed before root lookup is done
       -r disables recursive processing
       -R specifies number of retries for UDP packets
       -t specifies the query type
       -T enables TCP/IP mode
       -v enables verbose output
       -w specifies to wait forever for a reply
       -W specifies how long to wait for a reply

#hostname -h

Usage: hostname [-v] {hostname|-F file}      set host name (from file)
       domainname [-v] {nisdomain|-F file}   set NIS domain name (from file)
       hostname [-v] [-d|-f|-s|-a|-i|-y]     display formated name
       hostname [-v]                         display host name
       hostname -V|--version|-h|--help       print info and exit
    dnsdomainname=hostname -d, {yp,nis,}domainname=hostname -y
    -s, --short           short host name
    -a, --alias           alias names
    -i, --ip-address      addresses for the host name
    -f, --fqdn, --long    long host name (FQDN)
    -d, --domain          DNS domain name
    -y, --yp, --nis       NIS/YP domain name
    -F, --file            read host name or NIS domain name from given file
   This command can get or set the host name or the NIS domain name. You can
   also get the DNS domain or the FQDN (fully qualified domain name).
   Unless you are using bind or NIS for host lookups you can change the
   FQDN (Fully Qualified Domain Name) and the DNS domain name (which is
   part of the FQDN) in the /etc/hosts file.

    -y, --yp, --nis       NIS/YP domain name
    -F, --file            read host name or NIS domain name from given file
   This command can get or set the host name or the NIS domain name. You can
