I am trying to define number of array based on constant derived during execution phase of a script. Here is what i am trying..
My question is in the second part, where i am dynamically generating the Array name & then assigning element values to it depending on the counter.
For example:
For the first loop, i give two LUN numbers, say 10 & 11. So, my first array would be
my_lun[0]=10
my_lun[1]=11
For the second loop, since in generating the array name based on the LUN name & i give 3 values as elements for each array. So, my array should look like ( this is my question),
I'm attempting to populate an array in ksh using the following command:
set -A $(SELECT_INVOICE | sed '/^$/d')
SELECT_INVOICE is a function that executes the SQL query.
Problem: Some of the invoice numbers have alpha characters with spaces(example: OVEN MICRO). The Korn shell is treating... (1 Reply)
I read it is possible to provide values for an array with the -A option to the read statement; however, I have not been able to get this to work. When I execute a script with the -A option to the read statement, the shell complains that it is an illegal option. If this works, can someone provide... (5 Replies)

Hello,
I'm currently messing around with arrays for the first time in scripting (Unix Korn Shell). All I'm trying to do right now before I make things complicated is read through and print out to screen whether the read file is or is not a directory.
Here is my directory:

I have a korn shell script that reads a file with just one column in the file. If the file has more than 5 entries it is split using split -5. This means that is we have 15 entries I will end up with 3 files with 5 entries/lines in each and if I have 23 entries I will end up with 5 files with the... (2 Replies)

ARRAYS
XPC arrays are collections of XPC objects ordered by index. The index is zero-based. XPC arrays are contiguous, and values must exist at all
indexes between zero and the greatest index of the array. A hole in the array can be simulated by using a null object as returned by
xpc_null_create(3).
CREATION
The xpc_array_create() function returns a newly created array. The caller may optionally provide objects, a C array of XPC object references,
to initialize the array. The count is used to specify the size of the C array. If objects is NULL, then count must be zero. If count speci-
fies more elements than are actually present in values or if values is NULL and count is non-zero, the behavior is undefined.
GETTING AND SETTING VALUES
The xpc_array_append_value() function may be used to append a value to the end of an array. This operation increases the count of the values
in the array by one.
The value of a specific index in the array may be set using the xpc_array_set_value() function. The value must be non-NULL, and the index
must already exist (i.e. less than the count provided at creation or extended through previous append operations).
The value at a specific index of an array may be retrieved using the xpc_array_get_value() function. The result of getting a non-existing
index (i.e. one that was not specified at creation or through a previous append operation) in undefined.
PRIMITIVE GET AND SET FUNCTIONS
Various functions exist for retrieving primitive C and operating system types directly from an array without the need for an intermediate
boxed object. See xpc_object(3) for more information.
The special XPC_ARRAY_APPEND constant may be used to append a value to the end of the array instead of operating on a specific index.
