$ARGV contains the name of the current file when reading from <>.
@ARGV The array @ARGV contains the command-line arguments intended
for the script. "$#ARGV" is generally the number of arguments
minus one, because "$ARGV[0]" is the first argument, not the
program's command name itself. See "$0" for the command name.
So, you want @ARGV, not $ARGV:
print "@ARGV\n";

What do you expect this to do? Change "Bad" to "Good" for all lines of
test.txt? If so, you need to add the -p option to set up a loop:
c:\perl -pe "s/Bad/Good" test.txt
See perldoc perlrun for the details.
