edit [<filename>]
An ascii text editor is included in the JNOS distribution. A clone of the UNIX "ed" editor, is invoked from the console with the path to the file to be edited:
...> edit ftpusers
This option is enabled by compiling with both #define EDITOR and #define ED. A full-screen console-only editor is available if JNOS is compiled with both #define EDITOR and #define TED.
