up：如果字符数大于80，如何将命令包装成两行？

问题描述

在puppet中，如果define命令> 80个字符，我该如何包装成两行来实现？

In puppet, if define command is > 80 characters, how can I wrap into two line to do it?

  exec { 'create_domain':
    command => "some command exceed 80 character...........................................................how to do how to do?.......",
  }

推荐答案

有点丑陋，但是如果字符串中的最后一个字符是 \ 后跟换行符，然后字符串在下一行继续。我的 sample.pp 清单如下：

It's sort of ugly, but if the last character in a string is a \ followed by a newline, then the string is continued on the next line. My sample.pp manifest is below:

exec { 'wrapped_string_example':
  command => "/bin/echo 12345678901234567890123456789012345678901234567890\
wrapped > /var/tmp/test.txt";
}

使用 puppet运行此应用sample.pp 提供以下输出

$ puppet apply sample.pp
notice: /Stage[main]/Exec[wrapped_string_example]/returns: executed successfully
notice: Finished catalog run in 0.10 seconds

然后将创建的文件添加目录显示行已换行：

And catting the created file shows the lines have wrapped:

$ cat /var/tmp/test.txt 
12345678901234567890123456789012345678901234567890wrapped

请参见（自Puppet v2.7.0起）

See https://github.com/puppetlabs/puppet/blob/9fbb36de/lib/puppet/parser/lexer.rb#L537 (as of Puppet v2.7.0)

这也是一个已知问题：

Also this is sort of a known issue: http://projects.puppetlabs.com/issues/5022
