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-check-mailmap
GIT-CHECK-MAILMAP(1) Git Manual GIT-CHECK-MAILMAP(1)
NAME
git-check-mailmap - Show canonical names and email addresses of contacts
SYNOPSIS
git check-mailmap [options] <contact>...
DESCRIPTION
For each "Name <user@host>" or "<user@host>" from the command-line or standard input (when using --stdin), look up the person's canonical
name and email address (see "Mapping Authors" below). If found, print them; otherwise print the input as-is.
OPTIONS
--stdin
Read contacts, one per line, from the standard input after exhausting contacts provided on the command-line.
OUTPUT
For each contact, a single line is output, terminated by a newline. If the name is provided or known to the mailmap, "Name <user@host>" is
printed; otherwise only "<user@host>" is printed.
MAPPING AUTHORS
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.
