exec is called runinstead in Perl 6, but rakudo doesn't implement it yet.

The last releases of Rakudo support run($command), which is roughly the same as system(EXPR) in Perl 5. In the current development branch this has been renamed to shell() to conform to this change in the specification.

Perl 6 - second systems done right

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
