Hi Dianna,
I am not familiar with NAWK but I do know AWK which is pretty similar. awk has a variable called NF which tells you the number of fields in record based on your field separator. For example, if you have names in the following formats:

John Q. Public
Jane Doe
Bill Bob Joe Bob Johnson

the NF will be the following for each assuming your field separatore is a space (which is default by the way):

John Q. Public NF=3
Jane Doe NF=2
Bill Bob Joe Bob Johnson NF=4

You can then use the value of NF to determine which feild to extract permitted the last name is always the last "word" on the line. Here are some examples where this wouldn't work:

Thuston Howell III <- last name is not III
Tony Van Sant <- last name is two "words"

If you are new to shell programming, a great book about awk is "sed and awk" by O'Reilly:

Good Luck,
TioTony

GIT-SHORTLOG(1) 						    Git Manual							   GIT-SHORTLOG(1)

NAME
       git-shortlog - Summarize 'git log' output

SYNOPSIS
       git log --pretty=short | git shortlog [<options>]
       git shortlog [<options>] [<revision range>] [[--] <path>...]

DESCRIPTION
       Summarizes git log output in a format suitable for inclusion in release announcements. Each commit will be grouped by author and title.

       Additionally, "[PATCH]" will be stripped from the commit description.

       If no revisions are passed on the command line and either standard input is not a terminal or there is no current branch, git shortlog will
       output a summary of the log read from standard input, without reference to the current repository.

OPTIONS
       -n, --numbered
	   Sort output according to the number of commits per author instead of author alphabetic order.

       -s, --summary
	   Suppress commit description and provide a commit count summary only.

       -e, --email
	   Show the email address of each author.

       --format[=<format>]
	   Instead of the commit subject, use some other information to describe each commit.  <format> can be any string accepted by the --format
	   option of git log, such as * [%h] %s. (See the "PRETTY FORMATS" section of git-log(1).)

	       Each pretty-printed commit will be rewrapped before it is shown.

       -c, --committer
	   Collect and show committer identities instead of authors.

       -w[<width>[,<indent1>[,<indent2>]]]
	   Linewrap the output by wrapping each line at width. The first line of each entry is indented by indent1 spaces, and the second and
	   subsequent lines are indented by indent2 spaces.  width, indent1, and indent2 default to 76, 6 and 9 respectively.

	   If width is 0 (zero) then indent the lines of the output without wrapping them.

       <revision range>
	   Show only commits in the specified revision range. When no <revision range> is specified, it defaults to HEAD (i.e. the whole history
	   leading to the current commit).  origin..HEAD specifies all the commits reachable from the current commit (i.e.  HEAD), but not from
	   origin. For a complete list of ways to spell <revision range>, see the "Specifying Ranges" section of gitrevisions(7).

       [--] <path>...
	   Consider only commits that are enough to explain how the files that match the specified paths came to be.

	   Paths may need to be prefixed with "-- " to separate them from options or the revision range, when confusion arises.

MAPPING AUTHORS
       The .mailmap feature is used to coalesce together commits by the same person in the shortlog, where their name and/or email address was
       spelled differently.

       If the file .mailmap exists at the toplevel of the repository, or at the location pointed to by the mailmap.file or mailmap.blob
       configuration options, it is used to map author and committer names and email addresses to canonical real names and email addresses.

       In the simple form, each line in the file consists of the canonical real name of an author, whitespace, and an email address used in the
       commit (enclosed by < and >) to map to the name. For example:

	   Proper Name <commit@email.xx>

       The more complex forms are:

	   <proper@email.xx> <commit@email.xx>

       which allows mailmap to replace only the email part of a commit, and:

	   Proper Name <proper@email.xx> <commit@email.xx>

       which allows mailmap to replace both the name and the email of a commit matching the specified commit email address, and:

	   Proper Name <proper@email.xx> Commit Name <commit@email.xx>

       which allows mailmap to replace both the name and the email of a commit matching both the specified commit name and email address.

       Example 1: Your history contains commits by two authors, Jane and Joe, whose names appear in the repository under several forms:

	   Joe Developer <joe@example.com>
	   Joe R. Developer <joe@example.com>
	   Jane Doe <jane@example.com>
	   Jane Doe <jane@laptop.(none)>
	   Jane D. <jane@desktop.(none)>

       Now suppose that Joe wants his middle name initial used, and Jane prefers her family name fully spelled out. A proper .mailmap file would
       look like:

	   Jane Doe	    <jane@desktop.(none)>
	   Joe R. Developer <joe@example.com>

       Note how there is no need for an entry for <jane@laptop.(none)>, because the real name of that author is already correct.

       Example 2: Your repository contains commits from the following authors:

	   nick1 <bugs@company.xx>
	   nick2 <bugs@company.xx>
	   nick2 <nick2@company.xx>
	   santa <me@company.xx>
	   claus <me@company.xx>
	   CTO <cto@coompany.xx>

       Then you might want a .mailmap file that looks like:

	   <cto@company.xx>			  <cto@coompany.xx>
	   Some Dude <some@dude.xx>	    nick1 <bugs@company.xx>
	   Other Author <other@author.xx>   nick2 <bugs@company.xx>
	   Other Author <other@author.xx>	  <nick2@company.xx>
	   Santa Claus <santa.claus@northpole.xx> <me@company.xx>

       Use hash # for comments that are either on their own line, or after the email address.
