No. I found it in a *customise* buffer and set it there first.

Now, edited to fit into a system of a handful Emacsen, it is set as:

	'(comint-input-ring-file-name (concat desktop-dirname "/history"))

Desktop-dirname is defined in .emacs. In recent GNU Emacs 23 the  
variable's value is described as:

	comint-input-ring-file-name is a variable defined in `comint.el'.
	Its value is "~/.history"
	Local in buffer *shell*; global value is
	"~/.emacs.d/PDesktop-23/history"
	Documentation:
	*If non-nil, name of the file to read/write input history.
	See also `comint-read-input-ring' and `comint-write-input-ring'.
	
	This variable is buffer-local, and is a good thing to set in mode  
hooks.
	
	You can /customize/ this variable.

When I comment the comint-input-ring-file-name setting line, its  
value is simply "~/.history."

I retrieved the values by pasting comint-input-ring-file-name into  
*shell* buffer and pressing C-h v.
