why do you need awk to sort ?

you can simply use the sort command

Code:
$ sort input.txt
abc1
abc12
abc15
abc23

Code:
sort -k 1.4n infile

You should start checking the man page for commands.

I have man sort it says

Code:
       -k, --key=POS1[,POS2]
              start a key at POS1 (origin 1), end it at POS2 (default end of line)

BUT, I don't understand the "1" "." "4", how did you get them?
