No, I'm trying to do this:

cmlist01 has a b c d e
cmlist02 has f g h i
cmlist03 has j k l

For the total in cmlist01, I should see 5 items.
For the total in cmlist02, I should see 4 items.
For the total in cmlist03, I should see 3 items.

As a result, I could do:

print "There are ${#cmlist01[@]} items in $listnbr:"
which prints "There are 5 itmes in cmlist01."

However, I want to do all of this in a for loop and have it derive the cmlistnn from the variable $listnbr (which is does just fine as evidenced in the output from the print statement). However, if I try to get the count (number of items in the array) using listnbr (instead of hardcoding cmlistnn in each statement), all I ever get is 1.

If I set the variable listnbr=cmlist01, I should see 5 items, but am only seeing 1 when I do:

print "There are ${#listnbr[@]} items in $listnbr:"
which prints "There are 1 itmes in cmlist01."

The main part of the code that I need this for is:

Code:
while [ $i -lt ${#cmlist03[@]} ]
     do
          ID=${cmlist03[$i]}
          echo "Processing $i with ${cmlist03[$i]}"

Maybe you just can't do what I'm trying to do...

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.

SEE ALSO

     ConsoleMessage(8)

     rc(8)

     http://www.opensource.apple.com/projects/documentation/howto/html/SystemStarter_HOWTO.html

HISTORY

     The SystemStarter utility appeared in Darwin 1.0

     SystemStarter was extended in Darwin 6.0 to support partial startup and interprocess communication.
