Start by reading perlintro and Coping with Scoping and write subs like this 

sub cheat {
    my( $cheatfile ) = @_;
    open my($info), '<', $cheatfile or die "Can't open( $cheatfile ): 
+$!";
    while(<$info>){
        print $_;
    }
    close $info;
}

and use it like 

    cheat( "/home/cheatsheets/$prefix.txt" );

If you want help with that $session stuff, you'll have to explain what that is (How do I post a question effectively? ) although it could be buffering, terminal ansi escapes, or just something else.

in case of buffering :) Tutorials: Input and Output: Suffering from Buffering?
