You cannot use commands in a script that require user input as that would halt the script.
So for renaming the layouts in a script with just a pre- and/or suffix, the easiest way would to use a LISP that does the work for you. See code below.
You can use the TEST command to run with user input on your current drawing.
(defun c:Test ()
(if
(and
(setq T_Prefix (getstring T "\nPrefix: "))
(setq T_Suffix (getstring T "\nSuffix: "))
(or
(/= T_Prefix "")
(/= T_Suffix "")
)
)
(PreSufLayouts T_Prefix T_Suffix)
)
(princ)
)
(defun PreSufLayouts (PSL_Prefix PSL_Suffix / PSL_Layouts PSL_ActiveDoc)
(if
(and
(= (type PSL_Prefix) 'STR)
(= (type PSL_Suffix) 'STR)
(or
(/= PSL_Prefix "")
(/= PSL_Suxfix "")
)
)
(progn
(vla-StartUndoMark (setq PSL_ActiveDoc (vla-get-ActiveDocument (vlax-get-acad-object))))
(setq PSL_Layouts (vla-get-Layouts PSL_ActiveDoc))
(vlax-for PSL_Item PSL_Layouts
(if
(/= (strcase (vla-get-Name PSL_Item)) "MODEL")
(vla-put-Name PSL_Item (strcat PSL_Prefix (vla-get-Name PSL_Item) PSL_Suffix))
)
)
(vla-EndUndoMark PSL_ActiveDoc)
(mapcar 'vlax-release-object (list PSL_Layouts PSL_ActiveDoc))
)
)
)
For a script you need to use the syntax: (PreSufLayouts "" "\(10-20-17\)P") <-- mind the \ before the ( and ) in the suffix string!
Be sure the LISP is loaded in each drawing before using the command by loading it after opening each drawing (like in the script example below) or by adding it to your StartUp suite in AutoCAD (or other automatically loaded LISP). But if you automatically load the LISP in each drawing, you need to remove the (load ..... lines in the script.
Create the script something like this:
open "C:\Folder\Drawing-001.dwg"
(load "C:\\Folder2\\YourFile.LSP")
(PreSufLayouts "" "\(10-20-17\)P")
.qsave
.close
open "C:\Folder\Drawing-002.dwg"
(load "C:\\Folder2\\YourFile.LSP")
(PreSufLayouts "" "\(10-20-17\)P")
.qsave
.close
....
....
....
