I recommend to create a small Perl script: 

# file joined-echo.pl
print join('||', @ARGV), "\n";

[download]

And use system($^X, 'joined-echo.pl', @rest_of_your_args) for testing - that way you know exactly that the command you're testing doesn't do any magical argument processing on its own.

Perl 6 - second systems done right
