How can I use the output of a command in cfengine3

Question

I want to list a directory content and use the result somewhere else:

bundle agent test
{

   commands:
      "ls /tmp/test/";

    reports:
    ubuntu::
       "print output here for example";  
# or add it to a variable which is how I really want to use it.
 }

Answer 1

bundle agent test
{

    vars:
        "my_result" string => execresult("/bin/ls /tmp/test/","noshell");

    reports:
        ubuntu::
            "Output is : $(my_result)";  
}

See https://cfengine.com/manuals/cf3-solutions#Execresult-example

Answer 2

As of version 3.3.0, you can use the lsdir() function instead.

vars:
  "result" slist => lsdir("/tmp/test", ".*", "false");
