使用 awk 打印除第一个字段以外的所有内容

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
BF  Burkina Faso
BN  Brunei Darussalam

And I 'd like to invert the order, printing first everything except $1 and then $1:

United Arab Emirates AE

How can I do the "everything except field 1" trick?

Answer 1

Assigning $1 works but it will leave a leading space: awk '{first = $1; $1 = ""; print $0, first; }'

You can also find the number of columns in NF and use that in a loop.
