How do I tell awk I want the second to last and third to last tokens from a tab-delimited line?
I'm using a bash script. I have a tab delimited file with data that looks like
Afghanistan AF AFG 004
ALA Aland Islands AX ALA 248
Albania AL ALB 008
Algeria DZ DZA 012
I want to rewrite the data like so
AF=AFG
AX=ALA
AL=ALB
DZ=DZA
which boils down to extracting the third to last token, writing an equals, and then printing the second to last token. I thought "awk" could help me, but I don't know how to say "second to last". This doesn't cut it
awk '{print $2=$3}' /tmp/country_data.tsv
How can I extract the data in the way I want?
