   ## Options
 
     * `:into` - injects the result into the given collectable, defaults to `""`
-    * `:cd` - the directory to run the command on
+    * `:cd` - the directory to run the command in
     * `:env` - an enumerable of tuples containing environment key-value as binary
     * `:arg0` - set the command arg0
     * `:stderr_to_stdout` - redirects stderr to stdout when true


    * `:eagain` - there are no more available operating system processes

    * `:enametoolong` - the external command given was too long.

    * `:emfile` - there are no more available file descriptors
      (for the operating system process that the Erlang emulator runs in)

  `command` is expected to be an executable available in PATH
  unless an absolute path is given.

  `args` must be a list of strings which are not expanded
  in any way. For example, this means wildcard expansion will
  not happen unless `Path.wildcard/2` is used. On Windows though,
  wildcard expansion is up to the program.
