NAME
       ifdata - get network interface info without parsing ifconfig output

SYNOPSIS
       ifdata
[options] {iface}

DESCRIPTION
       ifdata can be used to check for the existence of a network interface,
       or to get information about the interface, such as its IP address.
       Unlike ifconfig or ip, ifdata has simple to parse output that is
       designed to be easily used by a shell script.

OPTIONS
       -h     Print out a help summary.

       -e     Test to see if the interface exists, exit nonzero if it does
              not.

       -p     Prints out the whole configuration of the interface.

       -pe    Prints "yes" or "no" if the interface exists or not.

       -pa    Prints the IPv4 address of the interface.

       -pn    Prints the netmask of the interface.

       -pN    Prints the network address of the interface.

       -pb    Prints the broadcast address of the interface.

       -pm    Prints the MTU of the interface.

       Following options are Linux only.

       -ph    Prints the hardware address of the interface. Exit with a
              failure exit code if there is not hardware address for the given
              network interface.

       -pf    Prints the flags of the interface.

       -si    Prints out all the input statistics of the interface.

       -sip   Prints the number of input packets.

       -sib   Prints the number of input bytes.

       -sie   Prints the number of input errors.

       -sid   Prints the number of dropped input packets.

       -sif   Prints the number of input fifo overruns.

       -sic   Print the number of compressed input packets.

       -sim   Prints the number of input multicast packets.

       -so    Prints out all the output statistics of the interface.

       -sop   Prints the number of output packets.

       -sob   Prints the number of output bytes.

       -soe   Prints the number of output errors.

       -sod   Prints the number of dropped output packets.

       -sof   Prints the number of output fifo overruns.

       -sox   Print the number of output collisions.

       -soc   Prints the number of output carrier losses.

       -som   Prints the number of output multicast packets.

       -bips  Prints the number of bytes of incoming traffic measured in one
              second.

       -bops  Prints the number of bytes of outgoing traffic measured in one
              second.
