How to convert a column to last five digits
Hi
Suppose I have a input.csv file like this
Fort, 2034440-3333
Honda, b293489289
Toyota, 23423000
How to convert the second column to the following format, there are only two cases:
a.if the last five character is a hyphen plus four numeric digit, keep the the last five digits before the hypen as well as everything after hyphen (including hyphen).
b. if the last five character doesn't contain a hyphen, keep the last five digits.
so the output.csv is:
Fort, 34440-3333
Honda, 89289
Toyota, 23000
Thanks, I guess this will be done in awk but I have no idea how to do it.

I have a file:

3455 500
5355 600
7777 700
The first line is the period. I want to concatenate the Period into every line using a one line command..I guess maybe awk or something. So the output would look like this:
3455 500 2009_11
5355 600 2009_11
7777 700 2009_11
