Awk help

[millhouze]

I have a file of a list of vehicles.

I have sorted them in ABC order and numbered the lines. How can I import this sort back into the original file?

I want a list with the numbered field added to the original file. The original file is not in ABC order.

EX:
(original file)
Chevy
Acura
Ford
Honda

(what I have with the command: sort -d cars | awk '{print NR, $0 }'
)
1 Acura
2 Chevy
3 Ford
4 Honda

(desired result)

2 Chevy
1 Acura
3 Ford
4 Honda

The command I used to get this so far is
sort -d cars | awk '{print NR, $0 }'

Try...

awk '{print NR, $0}' cars|sort -d -k2|awk '{print NR, $0}'|sort -n -k2|awk '{print $1,$3}'
