help with understanding array

help with understanding array

(OP)
Can someone explain why the array is being put back in itself?
I don't understand why this needs to happen FILE_ARRAY[ $(( IDX )) ]="${FILE_ARRAY[ $(( IDX )) ]} ${FILE}"


CODE --> ksh

set -A FILE_ARRAY
                (( IDX = 0 )) ; (( COUNT = 0 ))
                for FILE in ${FILES} ; do
                        (( COUNT += 1 ))
                        FILE_ARRAY[ $(( IDX )) ]="${FILE_ARRAY[ $(( IDX )) ]} ${FILE}"
                        (( COUNT % 100 == 0 )) && (( IDX += 1 ))
                done 

RE: help with understanding array


It is concatenating array + space + ${file}...in a loop.

RE: help with understanding array

PS: It's concatenating in groups of 100 files.
