Usage

wc [-lkszrwechv] [host] [port]

l             Listen for incoming connections. It is an error to
              use this option with a host specified.

k             Keep listening. Forces wc to stay listening 
              for another connection after its current
              connection is completed. It is an error to use
              this option without -l.

s             Specify host(s) on the network to send ICMP echo
              requests. The default timeout is 900 milliseconds.
              e.g.    wc -s 10.0.0.0/24

z             Specify port(s) on the host to scan for listening
              daemons using the connect() call. The default
              timeout is 750 milliseconds.
              e.g.    wc -z localhost 1-200

r             Do a reverse DNS lookup with ICMP echo requests. 
              e.g.    wc -sr 10.0.0.0/24

w timeout     The timeout in milliseconds for pings and connect
              scans.
              e.g.    wc -zw 100 localhost 1000-2000

e filename    Specify filename to execute after connect
              (use with caution). See -c for enhanced
              functionality. It is an error to use this
              option with -c, -s, or -z.
              e.g.    host A (10.0.0.2)>  wc -lk -e "cmd" 8118
                      host B (10.0.0.3)>  wc 10.0.0.2 8118

c command     Specify commands to pass to "cmd /c" for
              execution. It is an error to use this option
              with -e, -s, or -z.
              e.g.    host A (10.0.0.2)>  wc -l -c "dir" 8118
                      host B (10.0.0.3)>  wc 10.0.0.2 8118

h             Print this help page.

v             Print version.

host          Can be a numerical address or a symbolic
              hostname. If the -s option is specified, CIDR
              notation (IPv4 only) can be used to specify a
              range of hosts.

port          Port must be single integer. If the -z option
              is specified, a range of ports can be used instead.
