Sending an array member to file
This may be a dupe, but the problem is not complex,it is simple issue.

I can create an array of string(s) located in positioning parameters for further processing. Works as expected.

Now I like to send / write each string , space separated words , into a file.

Of course I tried different ways , but so far no success.

So I need help, again.


Here is the snippet of scrip



Code:
for i in {2..32..2}; do
  104  MenuArray[$i]=$i$Space$menuCommand
  106  #append to file  
  107 echo "$LINENO array $MenuArray[$i]"  
  108 pause


HERE IS THE PROBLEM 

 append array member  to file
 

 109  echo "$MenuArray[$i]" >> "$PWD$DEBUG_DIR$DEBUG_MENU"


  110  echo "$LINENO  appeded to file "
  111  pause   
  112  ((i++))
  113     MenuArray[$i]=$menuDescription
  114      ((i++))
  115       done     
  116        echo "${MenuArray[@]}"
  117 :<<"cut"


And here is an output - it "writes " an array member "index" to file



Code:
   	 	 	 	   + i=0
 + for i in {2..32..2}
 + MenuArray[$i]='2 CLI Command'
 + echo '107 array [2]'
 107 array [2]
 + pause
