Method: Puppet::Util::POSIX#get_posix_field

Defined in:
lib/vendor/puppet/util/posix.rb

#get_posix_field(space, field, id) ⇒ Object

Retrieve a field from a POSIX Etc object. The id can be either an integer or a name. This only works for users and groups. It’s also broken on some platforms, unfortunately, which is why we fall back to the other method search_posix_field in the gid and uid methods if a sanity check fails

Raises:
