Code:

#! /bin/bash

if [ $# -ne 4 ]  # If number of positional parameters are not equal to 4,
then             # Print warn msg and exit.
    echo "Need exactly 4 parameters. Exiting."
    exit
fi

for x in $2 $3 $4
do
    if [ -e $x ] # If target file exists, delete it.
    then         # Even otherwise, cp would overwrite it.
        rm -f $x # Some systems have an alias for cp as "cp -i".
    fi           # So cp would prompt the user if the target file needs can be over-written.
    cp $1 $x     # Same thing is achieved here by deleting and creating a fresh copy.
done

How to use:

finger.conf

FINGER.CONF(5)						      BSD File Formats Manual						    FINGER.CONF(5)

NAME

     finger.conf -- finger(1) alias configuration file

DESCRIPTION

     The optional finger.conf file is used to provide aliases that can be fingered by local and network users.	This may be useful where a user's
     login name is not the same as their preferred mail address, or for providing virtual login names than can be fingered.

     Lines beginning with ``#'' are comments.  Other lines must consist of an alias name and a target name separated by a colon.  A target name
     should be either a user, a forward reference to another alias or the path of a world readable file.

     Where an alias points to a file, the contents of that file will be displayed when the alias is fingered.

FILES

     /etc/finger.conf  finger(1) alias definition data base

EXAMPLES

     # /etc/finger.conf alias definition file
     #
     # Format alias:(user|alias)
     #
     # Individual aliases
     #
     markk:mkn
     john.smith:dev329
     john:dev329
     sue:/etc/finger/sue.txt
     #
     # Network status message
     #
     status:/usr/local/etc/status.txt
     #
     # Administrative redirects
     #
     root:admin
     postmaster:admin
     abuse:admin
     #
     # For the time being, 'sod' is sysadmin.
     #
     admin:sod
