• Display the whole configuration of the specified interface: ifdata -p eth0
• Indicate the [e]xistence of the specified interface via the exit code: ifdata -e eth0
• Display the IPv4 [a]dress and the [n]etmask of the specified interface: ifdata -pa -pn eth0
• Display the [N]etwork adress, the [b]roadcast adress, and the MTU of the specified interface: ifdata -pN -pb -pm eth0
• Display help: ifdata

ifdata [options] {iface}

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.

-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.
