I love using perl for these cases. Bash script can also be written but the code size will be big. I can still help you out if you need this only in bash.
Here is the perl snippet you can use. Perl is default on unix machines these days.
Code:
#! perl
die "Input a pattern as argument!" if (not $ARGV[0]);
@loggedOn = `who | cut -f1 -d " " | grep "^$ARGV[0]" | sort | uniq `;
die "Pattern doesn't match into any of the logged on users" if (not scalar @loggedOn);
foreach $i (@loggedOn) {
chomp $i;
$fullname = `grep "$i:" /etc/passwd | cut -d: -f5 | tr -s ',' ' ' | sed 's/\(.*\) \(.*\)/\2 \1/'`;
chomp $fullname;
print "WARNING: $i is not in passwd file\n" if (not $fullname);
next if not $fullname;
print "Hello ***$fullname\n";
}

mesg
MESG(1) User Commands MESG(1)NAME
mesg - display (or do not display) messages from other users
SYNOPSIS
mesg [option] [n|y]
DESCRIPTION
The mesg utility is invoked by a user to control write access others have to the terminal device associated with standard error output. If
write access is allowed, then programs such as talk(1) and write(1) may display messages on the terminal.
Traditionally, write access is allowed by default. However, as users become more conscious of various security risks, there is a trend to
remove write access by default, at least for the primary login shell. To make sure your ttys are set the way you want them to be set, mesg
should be executed in your login scripts.
ARGUMENTS
n Disallow messages.
y Allow messages to be displayed.
If no arguments are given, mesg shows the current message status on standard error output.
OPTIONS -v, --verbose
Explain what is being done.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
EXIT STATUS
The mesg utility exits with one of the following values:
0 Messages are allowed.
1 Messages are not allowed.
>1 An error has occurred.
FILES
/dev/[pt]ty[pq]?
SEE ALSO login(1), talk(1), write(1), wall(1), xterm(1)HISTORY
A mesg command appeared in Version 6 AT&T UNIX.
AVAILABILITY
The mesg command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/.
