evaluate STRING

Sometimes you need more complex things, for instance a pipeline or conditions.

In the following example, users starting with the letter "g" will be loaded into a variable USERS (and it will also check whether it contains something):

@ Loading some variables
  - output_to_var USERS is not empty_output evaluate 'cat /etc/passwd | egrep -e ^g'
  - echo $USERS  # now you can be sure there is something
