print last 2 fields of a line
Hi everyone, happy new year!

Can someone teach me how I can print the last 2 fields of every line in a file (lines don't have uniform number of fields), for example:

input file:
aaa bbb ccc ddd
eee fff ggg
hhh iii jjj
kkk lll mmm nnn ooo

output:
ccc ddd
fff ggg
iii jjj
nnn ooo

Thanks in advance!
