Source

    static VALUE
    etc_each_passwd(VALUE obj)
    {
    #ifdef HAVE_GETPWENT
        RETURN_ENUMERATOR(obj, 0, 0);
        each_passwd();
    #endif
        return obj;
    }

Iterates for each entry in the `/etc/passwd` file if a block is given.

If no block is given, returns the `Enumerator`.

The code block is passed an `Passwd` struct.

See `Etc.getpwent` above for details.

Example:

    require 'etc'

    Etc::Passwd.each {|u|
      puts u.name + " = " + u.gecos
    }

    Etc::Passwd.collect {|u| u.gecos}
    Etc::Passwd.collect {|u| u.gecos}
