ifconfig - How to extract netmask using /sbin/ip? -

-

i want replace ifconfig /sbin/ip. using ifconfig can see lines 

inet addr:xx.xxx.x.xx  bcast:xx.xxx.x.xx  mask:255.255.255.0

and can parse find netmask (255.255.255.0). how can achieve using /sbin/ip?

running ip a you'll output similar running ifconfig. specifically, you'll see line similar yours:

inet xx.xxx.x.xx/24 brd xx.xxx.x.xx

the /24 denotes subnet mask in slash notation.
