You can either connect STDIN to a file or to the user TTY, not both. It's like saying you can wear a bowtie or a necktie, but not both.

The simplest solution is probably to specify the name of the file, and use STDIN for user interaction. The name of the file is in @ARGV.

open( INFILE, "<$ARGV[0]" ) 
    or die "Culd not open $ARGV[0] $!";
 ....
close INFILE;
