Multi Dimensional array in bash

Shell Programming and Scripting

Hi, I'm developing a script which contains a multi dimensional array, however for some reason the array is not iterating.

When executing the script, services are listed as arguments from argument 2. Ex voice data sms.

service=${@:2};

for services in $service
do

data_call_type=CALL_TYPE;
data_term=DATA;
voice_call_type=CALL_TYPE;
voice_term=VOICE-MO;
sms_call_type=CALL_TYPE;
sms_term=SMS-MO;
fi


done

path_dir=$TMPDIR/

for services in $service
    do
			declare -a arr_cust=("A" "B" "C" "D" "E" "F" "G" "H" "I" "J")
			declare -a arr_ids=("124" "94" "61" "85" "95" "105" "106" "107" "134" "158")
			
			for index in ${!array[*]};
			do
			
            charged_data=`grep -s $data_call_type=$data_term $path_dir/* | grep -s ACS_CUST_ID=${arr_ids[$index]} | wc -l`
 notcharged_data=`grep -s $data_call_type=$data_term $path_dir/* | grep -s ACS_CUST_ID={arr_ids[$index]} | wc -l`


eval charged="\$charged_$services"
        eval notcharged="\$notcharged_$services"
        
echo ${services}_charged $charged > $OUTPUTDIR/$(basename $0 .sh).$services.${arr_cust[$index]}

The issue i'm finding is that the grep is not working properly :

grep -s ACS_CUST_ID=${arr_ids[$index]}

also I am noticing that array is not iterating over index of both arrays. what I am after is that the each index perform all greps for charged_data and notcharged_data and output to file with extension listing the value of the index from array 'arr_cust'.

Can someone provide some help where i'm wrong in the above?

Kindly ignore the fact that for loop is doubled. This is because there are additional if conditions in the script

is this not already being discussed here?: https://www.unix.com/shell-programming-and-scripting/276798-multi-dimensional-array.html#post303012300

Just to get a common understanding of some terms and some statements in your script

  • I can't see a multidimensional array. What would you call a multidim array? Why do you need it?
  • The arr_cust is used ONLY for the output file name - is that intended?
  • Both charged_data and notcharged_data are populated by exactly the same algorithm (except the $ sign is missing for the latter) - intended?
  • Both arr_cust and arr_ids are constants - why redefined in every loop iteration?
  • Same for the data_call et al. in the services loop.
  • No surprise the index loop doesn't work as it loops across the undefined array .
  • Some done s missing for several for loops.
  • What do you need the (deprecated, dangerous) eval commands for? Can't the result be achieved in another way?

All this is quite irritating and misleading. Why don't you post a decent input sample, the desired output for it, and describe the logics connecting the two in plain English?
