Run the code with the -x (--xtrace) option set and post the output.

Thanks for your answer

GNU bash, version 4.2.46(2)-release (x86_64-redhat-linux-gnu)

This is How the Array Looks:

This is the output with the -x option:

As you see i got no output from the array.

Hmmm - I missed to post the necessary IFS modification. Try again with this slightly modified version:

for IN in $(echo "${!ENTRIES[*]}" | tr ',' '\n' | sort -un)
  do    [ ! "${IN/[A-Z]}" = "$IN" ] && continue
        printf "%s %s %s %s\n" "${ENTRIES[$IN",IP"]}" "${ENTRIES[$IN",HOST1"]}" "${ENTRIES[$IN",HOST2"]}" "${ENTRIES[$IN",COMMENT"]}"
