... and if you call "system" with just one long string, then Perl opens the
system default shell between your script and the external application, you
wanted to start.
So wherever possible you should prefer to use:
system('somecommand', '--param1=somevalue', '--anotherparam');
and not:
system('somecommand --param1=somevalue --anotherparam');
The first one opens *two* processes (the shell and "somecommand") while the
second only opens one process and passes the arguments directly without any
shell in between.
