I have attempted to create an array consisting of two items: #0 and #1.
I am able to print the two items corrctly:
However, when I try to run a for loop to print both objects:
I get:
If there are two objects, why is the output on four lines? How do I loop on two lines?
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)

I need to implement the following logic and need some expert help from UNIX community.
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.
I've implemented # 1 and 2 using... (3 Replies)
Greetings,
DISCLAIMER: My shell scripting is rusty so my question may be borderline stupid. You've been warned.

Inside a zsh function, I create a local array with local -a arrayname and a local associative array with local -A arrayname.
I also can create an array using set, like this:

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

systemstarter
SystemStarter(8) BSD System Manager's Manual SystemStarter(8)NAME
SystemStarter -- Start, stop, and restart system services
SYNOPSIS
SystemStarter [-gvxdDqn] [action [service]]
DESCRIPTION
The SystemStarter utility may be used to start, stop, and restart the system services which are described in the /Library/StartupItems/ and
/System/Library/StartupItems/ paths.
The optional action argument specifies which action SystemStarter performs on the startup items. The optional service argument specifies
which startup items to perform the action on. If no service is specified, all startup items will be acted on; otherwise, only the item pro-
viding the service, any items it requires, or any items that depend on it will be acted on.
During boot SystemStarter is invoked by rc (see rc(8)) and is responsible for starting all startup items in an order that satisfies each
item's requirements.
ACTIONS
start start all items, or start the item that provides the specified service and all items providing services it requires.
stop stop all items, or stop the item that provides the specified service and all items that depend on it.
restart restart all items, or restart the item providing the specified service.
OPTIONS -g graphical startup
-v verbose (text mode) startup
-x safe mode startup (only run Apple-provided items)
-r keep running after last startup item completes, in graphical startup only
-d print debugging output
-D print debugging output and dependencies
-q be quiet (disable debugging output)
-n don't actually perform action on items (no-run mode)
NOTES
Unless an explicit call to ConsoleMessage is made, SystemStarter examines the exit status of the startup item scripts to determine the suc-
cess or failure of the services provided by that script.
In Darwin it is preferable to create custom startup items than to modify rc, and at some point SystemStarter may entirely encompass the role
of rc.
FILES
/Library/StartupItems/ User-installed startup items.
/System/Library/StartupItems/ System-provided startup items.
