+====== rc, ed, network configuration ======
+===== rc: the  Plan 9 shell =====
+    * **ctl-h** is backspace, kind of; **ctl-u** erases the current line. As seen, with the VPS Plan 9 console prompt **ctl-h** backspace, the screen output may not be what one would expect (([[http://sdf.org/?tutorials/Plan_9_rc|Control keys]] – Available at the SDF Boot Camp VPS server console prompt)).
+    * To detach the Plan 9 console prompt (%), while retaining the ability to reattach it __without__ rebooting your server, press **ctl-]** to close the prompt (%). Then, press ‘**q**’ to disconnect the VPS Maintenance Shell menu, and ssh connection. You can return again with another [[:plan9front_-_plan_9_instance_under_xen#default_pre-generated_installation|ssh]] to the allocated VPS server, an SDF VPS Maintenance Shell menu review, and a press on the “**c**” key to connect to the Plan 9 console prompt (%).
+    * //**ed**// and “''% sam -d''” are available in the Plan 9 Image. They may be used for setting the DNS, or other tasks from the Plan 9 VPS console prompt (%), before Drawterm is accessible. An [[http://sdf.org/?tutorials/ed | ed cheat-sheet]] is available. Additional editors are operational from a [[:plan9front_-_drawterm_rio_and_stats#drawterm|Drawterm]] Rio rc prompt: acme, [[:plan9front_-_acme_sam_abaco_mothra_and_man#sam|sam]], or ''% sam -d''.
+|% [[:plan9front_-_acme_sam_abaco_mothra_and_man#sam|sam -d]]| Editing will be done with the command language only, as in //ed//.|
+=== Configuring a dynamic prompt ===
+To have a prompt that shows your [[plan9front_-_fn_reply_and_prompt#prompt|pwd and user name]], add the following lines to your lib/profile. Place them in the ‘case cpu’ section, replacing the cpu% prompt line.
+<code>
+prompt=('['^`{pwd}^'] '^$sysname^'% ' ' ')
+fn cd {builtin cd $* && prompt=('['^`{pwd}^'] '^$sysname^'% ' ' ')}
+</code>
+These lines update the prompt, and replace the ‘cd’ command so that the prompt is updated each time you change a directory.
+===== ed =====
+Ed is a text editor, and similar to [[:plan9front_-_acme_sam_abaco_mothra_and_man#sam|sam -d]]. Using the ''% sam -d'' examples from [[:plan9front_-_acme_sam_abaco_mothra_and_man#sam|Sam]], it's possible to use ''% ed''. The mentioned examples are from a Drawterm Rio rc prompt.
+<code>
+  % cd samtest
+  % cp /lib/ndb/local local-1ed
