Printing everything except the first field with awk

Question

I have a file that looks like this:

AE  United Arab Emirates
AG  Antigua & Barbuda
AN  Netherlands Antilles
AS  American Samoa
BA  Bosnia and Herzegovina         


        

Answer 1

Maybe the most concise way:

$ awk '{$(NF+1)=$1;$1=""}sub(FS,"")' infile
United Arab Emirates AE
Antigua & Barbuda AG
Netherlands Antilles AN
American Samoa AS
Bosnia and Herzegovina BA
Burkina Faso BF
Brunei Darussalam BN

Explanation:

$(NF+1)=$1: Generator of a "new" last field.

$1="": Set the original first field to null

sub(FS,""): After the first two actions {$(NF+1)=$1;$1=""} get rid of the first field separator by using sub. The final print is implicit.
