Thanks for the response!. The approach without using the array is very helpful. What would be the change if the delimiter is not spaces
The shell has a special variable you can set, IFS, to change its internal delimiter. It is not any sort of regex, only a list of characters which are valid "splitters". By default it is space, newline, and tab. It's only used for variable quoting purposes and some builtins like read. So:
Code:
OLDIFS="$IFS" ; IFS=","
VAR="1,2,3,4,5,6,7,8,9,10"
for X in $VAR
do
echo $X
done
I currently run a script over a vpnc tunnel to back-up my data to a remote server. However for a number of reasons the tunnel often collapses. If I manually restore the tunnel then the whole thing can continue, but I want to add into my script a section whereby while the transfer is taking place,... (8 Replies)

you can also use them "on the command line when running a script..." and it lists this in a small table:

I am trying to look through one of my directories to remove certain files. I am pretty new to Unix and bash so I just need a little help in starting this. I know I would have to write two loops one to iterate the directories and one to iterate the files. How would I write the loops? (3 Replies)

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).
