We just purchased a MOD30 disk array strage system.
We have 15 drives and 2 hot spares.
We're running a database app with 8 data sets.
I'm trying to get the best i/o speed out of my disk configuration.
Right now I have 3 raid5 arrays setup. This seems to offer the same performance as having the... (1 Reply)
When setting a variable, how would I go about making each result a new line?
A very simple example would be:
theFolders=`(ls -l /)`
echo $theFolders
This gives me all the folders as one variable and I need to be able to use each as its own variable. I'm sure I have to make this into an... (2 Replies)

These are the steps in my Shell script.
1. Analyze a file.
2. Extract all the ID's in that file.
3. Use the ID's from #2 to run another filter on the file.

Greetings,
DISCLAIMER: My shell scripting is rusty so my question may be borderline stupid. You've been warned.
I need to create a script that a) lists the content of zip files in a directory and b) sends out an `exception` report. My ZIP files contain a control file (for load check). I want... (2 Replies)

I am trying to assign indexes to an associative array in a for loop but I have to use an eval command to make it work, this doesn't seem correct I don't have to do this with regular arrays

LEARN ABOUT PHP
current
CURRENT(3) 1 CURRENT(3)current - Return the current element in an arraySYNOPSIS
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).
