如何在 Exec 资源类型中执行 bash 命令行？

Question

我有这个 Exec 声明：

    exec { 'Normalize MP3 filename':
            environment => ["t=0"],
            command => 'for i in *mp3; do  mv -v $i track_`seq -f "%03g" $t $t`.mp3 ; t=`expr $t + 1`; done',
            cwd     => "$resource_path/res/raw",
    } ->

当我的清单运行时出现此错误：

Error: Could not find command 'for'
Error: /Stage[main]/Make_it::App_mp3files/Exec[Normalize MP3 filename]/returns: change from notrun to 0 failed: Could not find command 'for'

Answer 1

*nix 操作系统上的默认 exec 提供程序是 posix，即 does not support shell built-ins such as for。您应该将提供程序更改为 shell 以使用 shell 内置函数。

exec { 'Normalize MP3 filename':
        environment => ["t=0"],
        command => 'for i in *mp3; do  mv -v $i track_`seq -f "%03g" $t $t`.mp3 ; t=`expr $t + 1`; done',
        cwd     => "$resource_path/res/raw",
        provider => 'shell',
} ->
