How to find particular interface name and status from ifconfig command?

When I use ifconfig command, it will show the details of all active devices.

I want the interface name only, and want to check whether the interface is running or not.

ifconfig | grep interface-name

This will give all detail about the interface but I want to print only interface name.

To see (only) Interface Name, IF Name, you could try these commands in the Terminal (from name of my Network Interface?):

ip route list | grep default | awk '{print $5} ' This is for the default route.
or
ls /sys/class/net This is for all names.

Since you have the interface name, you can do the following:

$ ifconfig interface-name &> /dev/null
$ echo $?

If the output is 0, the interface exists, otherwise, it doesn't.
