From the keyboard of m23364@mwunix (James Meritt):
:It's no big deal to get the real name of the person who is executing a script
:(to me, anyway) UNLESS the system is using yellow pages.  How do I then?
:otherwise, I just use:
:		grep $user /etc/passwd | cut -d: -f5

Try:

    user=${LOGNAME-${USER-`whoami`}}
    if [ x`domainname` = x ]; then 
	ypmatch $user passwd
    else 
	grep $user /etc/passwd
    fi | cut -d: -f5  | sed -e 's/,.*//' -e 's/&/$user/g'

Although it would be better to avoid cut.  You can do it all in sed
anyway, and not everyone has cut, so turn the fi line into:

    fi | sed -e "s/[^:]*:[^:]*:[^:]*:[^:]*:\([^:]*\).*/\1/ 
		 s/,.*//
		 s/&/$user/g"


Using perl:

    #!/usr/bin/perl
    ($login, $name) =  (getpwuid($>))[0,6];
    $name =~ s/,.*//;
    $name =~ s/&/$login/g;
    print "$name\n";

or simply 

    perl -le 'print ((getpwuid($>))[6]  =~ /([^,]+)/)'

If you don't care about &-processing.
