Top Forums UNIX for Advanced & Expert Users Insert string in binary file at top Post 302526168 by Loic Domaigne on Monday 30th of May 2011 03:43:09 PM

Buy faster disks, perhaps? Smilie

Seriously, I am not aware of an efficient general solution for this kind of problem... Does anybody know one? ...

How is this binary produced? Perhaps you can avoid to write the file twice using e.g. pipe or redirection and appending first the EBCDIC stream. But this assumes that you have somehow access to the program that generates this binary.

My guess is that all bet are lost if you're trying to append the string at the beginning of the file after it has been created.

Just my 2c,
Loïc

NAME
bj - the game of black jack SYNOPSIS
/usr/games/bj DESCRIPTION
Bj is a serious attempt at simulating the dealer in the game of black jack (or twenty-one) as might be found in Reno. The following rules apply: The bet is $2 every hand. A player `natural' (black jack) pays $3. A dealer natural loses $2. Both dealer and player naturals is a `push' (no money exchange). If the dealer has an ace up, the player is allowed to make an `insurance' bet against the chance of a dealer natural. If this bet is not taken, play resumes as normal. If the bet is taken, it is a side bet where the player wins $2 if the dealer has a natural and loses $1 if the dealer does not. If the player is dealt two cards of the same value, he is allowed to `double'. He is allowed to play two hands, each with one of these cards. (The bet is doubled also; $2 on each hand.) If a dealt hand has a total of ten or eleven, the player may `double down'. He may double the bet ($2 to $4) and receive exactly one more card on that hand. Under normal play, the player may `hit' (draw a card) as long as his total is not over twenty-one. If the player `busts' (goes over twenty-one), the dealer wins the bet. When the player `stands' (decides not to hit), the dealer hits until he attains a total of seventeen or more. If the dealer busts, the player wins the bet. If both player and dealer stand, the one with the largest total wins. A tie is a push. The machine deals and keeps score. The following questions will be asked at appropriate times. Each question is answered by y followed by a new line for `yes', or just new line for `no'. ? (means, `do you want a hit?') Insurance? Double down? Every time the deck is shuffled, the dealer so states and the `action' (total bet) and `standing' (total won or lost) is printed. To exit, hit the interrupt key (DEL) and the action and standing will be printed. BJ(6)
