We need the ability to sort a list alphabetically on a person's last name.
For example, given a file like this:












how should I use sort to alphabetize on the names after the first period??

Thanks!!

did you read your 'sort' man pages _?_

$ sort -t. +1 input_file -o output_file
       ^^^^^^

Any decent version of 'sort' will be able to do what you need:

sort -t. +1

All this nifty sorting is of course described in the man page. If your current
'sort' is not able to do that get the GNU fileutils. The GNU version of 'sort'
will do that job ...

good luck.

you can use `sort' command. Fistly type `man sort'.
maybe
        sort -d -t. +2 <file-name> ( not tested )
will help u.

1. how to sort ip addresses using sort(1)

Hello sort gurus,

here's a little problem that's driving me nuts: I have a file with
IP addresses in dot notation, one per line, that I want to sort in
numerical order (as if they were 32bit numbers). The trouble is, that
a naive sort -n does not work, because IP adresses look like
floats only up to the second dot. Using '.' as a field delimiter does
not help either (i.e. sort -t. -n).
I wonder if there is a solution using sort(1) _alone_. I know it can be
done using perl with a custom sort function and in a plethora of
other ways involving tr,cut,whatnot etc. But that's not what
I'm looking for. I'm rather interested in a proof of concept that sort(1)
can also solve this problem.
Solutions requiring GNU sort are welcome.

Any takers?
