Another prompt option.

[Jeremias-A-Queiroz]

This is my eshell prompt:

(setq eshell-prompt-function
      (lambda ()
	(concat
	 (propertize "┌─[" 'face `(:foreground "green"))
	 (propertize (user-login-name) 'face `(:foreground "red"))
	 (propertize "@" 'face `(:foreground "green"))
	 (propertize (system-name) 'face `(:foreground "blue"))
	 (propertize "]──[" 'face `(:foreground "green"))
	 (propertize (format-time-string "%H:%M" (current-time)) 'face `(:foreground "yellow"))
	 (propertize "]──[" 'face `(:foreground "green"))
	 (propertize (concat (eshell/pwd)) 'face `(:foreground "white"))
	 (propertize "]\n" 'face `(:foreground "green"))
	 (propertize "└─>" 'face `(:foreground "green"))
	 (propertize (if (= (user-uid) 0) " # " " $ ") 'face `(:foreground "green"))
		)))

Looks like it:

┌─[username@hostname]──[10:15]──[/dir/subdir]
└─> $
