Great thanks, I'll give that a go. I'm a real BASH noob, so I'd never have managed to get that solution, or anything close to it I think.

Do I need to make a separate script with the contents bring the code in the code section, and then call it from the awk command ? Or can I put the whole lot into a single command that I can paste into a command prompt ?

menu_driver(3CURSES)					     Curses Library Functions					      menu_driver(3CURSES)

NAME
menu_driver - command processor for the menus subsystem SYNOPSIS
cc [ flag... ] file... -lmenu -lcurses [ library... ] #include <menu.h> int menu_driver(MENU *menu, int c); DESCRIPTION
menu_driver() is the workhorse of the menus subsystem. It checks to determine whether the character c is a menu request or data. If c is a request, the menu driver executes the request and reports the result. If c is data (a printable ASCII character), it enters the data into the pattern buffer and tries to find a matching item. If no match is found, the menu driver deletes the character from the pattern buffer and returns E_NO_MATCH. If the character is not recognized, the menu driver assumes it is an application-defined command and returns E_UNKNOWN_COMMAND. Menu driver requests: REQ_LEFT_ITEM Move left to an item. REQ_RIGHT_ITEM Move right to an item REQ_UP_ITEM Move up to an item. REQ_DOWN_ITEM Move down to an item. REQ_SCR_ULINE Scroll up a line. REQ_SCR_DLINE Scroll down a line. REQ_SCR_DPAGE Scroll up a page. REQ_SCR_UPAGE Scroll down a page. REQ_FIRST_ITEM Move to the first item. REQ_LAST_ITEM Move to the last item. REQ_NEXT_ITEM Move to the next item. REQ_PREV_ITEM Move to the previous item. REQ_TOGGLE_ITEM Select/de-select an item. REQ_CLEAR_PATTERN Clear the menu pattern buffer. REQ_BACK_PATTERN Delete the previous character from pattern buffer. REQ_NEXT_MATCH Move the next matching item. REQ_PREV_MATCH Move to the previous matching item. RETURN VALUES
menu_driver() returns one of the following: E_OK The routine returned successfully. E_SYSTEM_ERROR System error. E_BAD_ARGUMENT An incorrect argument was passed to the routine. E_BAD_STATE The routine was called from an initialization or termination function. E_NOT_POSTED The menu has not been posted. E_UNKNOWN_COMMAND An unknown request was passed to the menu driver. E_NO_MATCH The character failed to match. E_NOT_SELECTABLE The item cannot be selected. E_REQUEST_DENIED The menu driver could not process the request. ATTRIBUTES

Application-defined commands should be defined relative to (greater than) MAX_COMMAND, the maximum value of a request listed above. The header <menu.h> automatically includes the headers <eti.h> and <curses.h>. SunOS 5.11 31 Dec 1996 menu_driver(3CURSES)
