awk to indent file outout
i have a file that contains information such as this:


Code:
hostname.sky.net     ===     12.39.59.35
hostname.sky.net     ===     12.39.59.35
hostname.sky.net     ===     12.39.59.35
hostname-newyork.sky.net      ====      13.45.35.24
hostname-newyork.sky.net      ====      13.45.35.24
hostname-newyork.sky.net      ====      13.45.35.24

As you can see here, because the hostname containing "newyork" is longer, it messes up the alignment of the output.

how can i make awk tab each line so they are perfected aligned?

the preferred output would be something like:

Code:
hostname.sky.net                ====      12.39.59.35
hostname.sky.net                ====      12.39.59.35
hostname.sky.net                ====      12.39.59.35
hostname-newyork.sky.net        ====      13.45.35.24
hostname-newyork.sky.net        ====      13.45.35.24
hostname-newyork.sky.net        ====      13.45.35.24

I tried this:

Code:
awk '{printf "\t% s\t% s\t% s\t% s\n",$1,$2,$3,$4}'

but i'm sure it is just wrong.
