-====== 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<sup>1</sup>.
-    * 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 [[:vps_-_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 [[:vps_-_plan9front_-_drawterm_rio_and_stats#drawterm|Drawterm]] Rio rc prompt: acme, [[:vps_-_plan9front_-_acme_sam_abaco_mothra_and_man#sam|sam]], or ''% sam -d''.
-|% [[:vps_-_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 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 [[:vps_-_plan9front_-_acme_sam_abaco_mothra_and_man#sam|sam -d]]. Using the ''% sam -d'' examples from [[:vps_-_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.
