Rather than wrestling with the shell to do this - make it easy on yourself and use Perl - for example, to only print the line if the user enters a 1....
Code:
#!/usr/bin/perl

open( FOOFILE, "< foofile" );
while( <FOOFILE> ) {
  print( "Enter a number: " );
  chomp( $input = <STDIN> );
  if ( $input == 1 ) {
    print( "You entered a 1 and the line is $_" );
  } else {
    print( "Ooops - not a 1\n" );
  }
}
close( FOOFILE );

Cheers
