Is it possible to store a linux command result in variable?
是否可以将linux命令结果存储在变量中？
I am trying to store an encrypted value in a variable. To encrypt I am using base64 command. To store it in variable, I am using generate method. But I am not able to store a value.
我试图将加密值存储在变量中。加密我正在使用base64命令。要将它存储在变量中，我使用的是generate方法。但我无法存储价值。
$secretvalue = generate("/bin/bash","-c","/usr/bin/echo ${password} | /usr/bin/base64")

If you want to execute any command on Puppet Master server you can use inline_template function with ERB template inside and Ruby code for execute shell command:
如果要在Puppet Master服务器上执行任何命令，可以使用带有ERB模板的inline_template函数和用于执行shell命令的Ruby代码：
$password = "12345"
$secretvalue = inline_template("<%= `/bin/echo ${password} | /usr/bin/base64` %>")
notify { "STDOUT: ${secretvalue}": }
P.S. If you just want to encode string to Base64 format you can import puppetlabs-stdlib module and use base64 function from it:
附：如果您只想将字符串编码为Base64格式，您可以导入puppetlabs-stdlib模块并使用它的base64函数：
$secretvalue = base64('encode', $password)
