There are no UNIX dummies, only those who have not been enlightened by it's power! Welcome.
To exectute a program in UNIX, it must first be executable. If the perl script is named msgbd.pl, from the directory where the script is stored, type
ls -l msgbd.pl
You should see something like;
-rwxr-xr-- 1 keith site32 703 Jan 11 12:14 msgbd.pl
What you are looking for is the x in rwxr--r--. This is the permission set associated with this file. It is split into three sets, owner, group, and everyone. This file had read, write and execute for the owner, read and execute for the group, and read for everyone. To make it exectutable for everyone, type;
chmod +x msgbd.pl
To execute the program, cd into the directory where the script is, and type;
./msgbd.pl
The ./ means this directory. It may be in your " search path" and not require the ./, but it may not.

CHMOD(1) General Commands Manual CHMOD(1)
NAME
chmod - change mode
SYNOPSIS
chmod mode file ...
DESCRIPTION
The mode of each named file is changed according to mode, which may be an octal number or a symbolic change to the existing mode. A mode
is an octal number constructed from the OR of the following modes.
0400 read by owner
0200 write by owner
0100 execute (search in directory) by owner
0070 read, write, execute (search) by group
0007 read, write, execute (search) by others
A symbolic mode has the form:
[who] op permission
The who part is a combination of the letters u (for user's permissions), g (group) and o (other). The letter a stands for ugo. If who is
omitted, the default is a.
Op can be + to add permission to the file's mode, - to take away permission, and = to assign permission absolutely (all other bits will be
reset).
Permission is any combination of the letters r (read), w (write), x (execute), a (append only), and l (exclusive access).
Only the owner of a file or the group leader of its group may change the file's mode.
