So, why doesn't the page tell me how to determine the needed
entry given that my program is a script and really just wants
the full user name of the current user? Specifically, how can
it be used to simplify the following:
lname=`id | sed 's/ .*//;s/)//;s/.*(//'`
fname=`getent passwd $lname | awk -F: '{ print $5 }'`
the main complexities are:
1. lname may appear as 'uid=1234'
2. getting lname is a hassle anyway
3. Remembering that the user name is the fifth field is much harder
to remember than ``getpwnam -h'' or ``getent passwd me'' and
count colons
4. two pipes + two subshells
Ick.

Neither one is the usual usage:
$ getpwnam -N

That's really easy to parse.
