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?

`awk '{printf "%s=%s\
", $(NF-2),$(NF-1)}' file`
