You're an absolute star - thank you so much.
My issue was that I have to run it (exactly the same command request) on 50+ (nearer to 100) devices. So being able to logon to each device and just paste in a script on the commd line is so much simpler that needing to create a file on each device.

Hello,
I try to write a shell script that would list all files on a directory and stop when it finds the first item specified on a find or ls command.
How can I tell to the find or ls command to stop when it finds the first ".doc" file for example ?

menu_driver
MENU_DRIVER(3) BSD Library Functions Manual MENU_DRIVER(3)
NAME
menu_driver -- main menu handling function
LIBRARY
Curses Menu Library (libmenu, -lmenu)
SYNOPSIS
#include <menu.h>
int
menu_driver(MENU *menu, int c);
DESCRIPTION
The menu_driver() function is the guts of the menu system. It takes the commands passed by c parameter and performs the requested action on
the menu given. The following commands may be given to the menu driver:
Command Action
REQ_LEFT_ITEM Sets the new current item to be the item to the left of the current item.
REQ_RIGHT_ITEM Sets the new current item to be the item to the rights of the current item.
REQ_UP_ITEM Sets the new current item to be the item above the current item.
REQ_DOWN_ITEM Sets the new current item to be the item below the current item.
REQ_SCR_ULINE Scroll the menu one line towards the bottom of the menu window. The new current item becomes the item immediately above
the current item.
REQ_SCR_DLINE Scroll the menu one line towards the top of the menu window. The new current item becomes the item immediately below the
current item.
REQ_SCR_DPAGE Scroll the menu one page towards the bottom of the menu window.
REQ_SCR_UPAGE Scroll the menu one page towards the top of the menu window.
REQ_FIRST_ITEM Set the current item to be the first item in the menu.
REQ_LAST_ITEM Set the current item to be the last item in the menu.
REQ_NEXT_ITEM Set the new current item to be the next item in the item array after the current item.
REQ_PREV_ITEM Set the new current item to be the item before the current item in the items array.
REQ_TOGGLE_ITEM If the item is selectable then toggle the item's value.
REQ_CLEAR_PATTERN Clear all the characters currently in the menu's pattern buffer.
REQ_BACK_PATTERN Remove the last character from the pattern buffer.
REQ_NEXT_MATCH Attempt to find the next item that matches the pattern buffer.
REQ_PREV_MATCH Attempt to find the previous item that matches the pattern buffer.
If menu_driver() is passed a command that is greater than MAX_COMMAND then the command passed is assumed to be a user defined command and
menu_driver() returns E_UNKNOWN_COMMAND. Otherwise if the command is a printable character then the character represented by the command is
placed at the end of the pattern buffer and an attempt is made to match the pattern buffer against the items in the menu.
RETURN VALUES
The functions return one of the following error values:
E_OK The function was successful.
E_SYSTEM_ERROR There was a system error during the call.
E_BAD_ARGUMENT One or more of the arguments passed to the function was incorrect.
E_NOT_POSTED The menu is not posted.
E_UNKNOWN_COMMAND The menu driver does not recognize the request passed to it.
E_NO_MATCH The character search failed to find a match.
E_NOT_CONNECTED The item is not connected to a menu.
E_REQUEST_DENIED The menu driver could not process the request.
