;; `eshell-info-banner' is a utility for creating an informative
|
2021-05-17 15:14:43 +00:00
|
|
|
|
;; banner akin to fish_greeting if fish shell but for Eshell. It can
|
|
|
|
|
;; provide information on:
|
|
|
|
|
;; - the OS’ name
|
|
|
|
|
;; - the OS’ kernel
|
|
|
|
|
;; - the hostname
|
|
|
|
|
;; - the uptime
|
|
|
|
|
;; - the system’s memory usage (RAM, swap, disk)
|
|
|
|
|
;; - the battery status
|
|
|
|
|
;; It can be TRAMP-aware or not, depending on the user’s preferences.
