Question

如何在 Perl6 中执行外部命令并捕获其输出？

Perl5 风格的反引号似乎不起作用:

> my $results = `ls`;
Confused at line 1, near "my $results"

Synopsis 16记录 run 方法，但这返回退出状态而不是 stdout 的输出。

我正在使用 Rakudo 实现 (rakudo-star-2010.12)。

使用 qqx 或 qx 代替，例如:

> my $results = qqx{ls};

拉里·沃尔 answered邮件列表上的等效问题:

: What replaces backtick or qx{} ?

qqx[] or qq:x[] would be the exact equivalent. qx[] or q:x[] would be the same with single-quote semantics. (There are probably no backticks for that purpose since we're reserving ` for user-defined stuff, and because backticks are visually difficult to tell from single quotes in many fonts.)
