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

       report will be more complete if stap-report is run as root.

	      $ stap-report > report.txt
	      $ head report.txt
	      == id ==
	      uid=1000(user) gid=1000(user) groups=122(stapdev),123(stapusr),129(stapsys)
