Top Forums Shell Programming and Scripting Ignore the 255 character limit of command line Post 302574817 by Corona688 on Friday 18th of November 2011 11:22:55 AM

Just to make this clear:

There's no way to "ignore" argument length limits or argument size problems. That's a system limitation. 255 characters is an unusually severe limit, but there's always a limit. No shell syntax is ever going to fit a 10-foot truck under an 8-foot tunnel.

I've seen people pile on more and more braces, backticks, and eval until the shell stops saying "too many arguments" but it's still a 10-foot truck and 8-foot tunnel. If you made it fit, you must have wrecked the truck.

If it won't fit as an argument, you have to pass it by other means, like a file.

current - Return the current element in an array

SYNOPSIS
mixed current (array &$array) DESCRIPTION
Every array has an internal pointer to its "current" element, which is initialized to the first element inserted into the array. PARAMETERS
o $array - The array. RETURN VALUES
The current(3) function simply returns the value of the array element that's currently being pointed to by the internal pointer. It does not move the pointer in any way. If the internal pointer points beyond the end of the elements list or the array is empty, current(3) returns FALSE. Warning This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function. EXAMPLES
Example #1 Example use of current(3) and friends <?php $transport = array('foot', 'bike', 'car', 'plane'); $mode = current($transport); // $mode = 'foot'; $mode = next($transport); // $mode = 'bike'; $mode = current($transport); // $mode = 'bike'; $mode = prev($transport); // $mode = 'foot'; $mode = end($transport); // $mode = 'plane'; $mode = current($transport); // $mode = 'plane'; $arr = array(); var_dump(current($arr)); // bool(false) $arr = array(array()); var_dump(current($arr)); // array(0) { } ?> NOTES
Note You won't be able to distinguish the end of an array from a boolean FALSE element. To properly traverse an array which may contain FALSE elements, see the each(3) function. SEE ALSO
end(3), key(3), each(3), prev(3), reset(3), next(3). PHP Documentation Group CURRENT(3)
