slash etc profile

chksectorcount() {
  local -a drives=(/dev/sd*)

  # Iterate through array to remove partitions i.e /dev/sda1 and so on
  ((n_elements=${#drives[@]}, max_index=n_elements - 1))

  for ((i = 0; i <= max_index; i++)); do
    if [[ $(echo ${drives[i]} | grep -v '[0-9]') ]]; then
      smartctl -a ${drives[i]} | grep "Sector Sizes:"|sed "s:^:${drives[i]} :"
    else
      unset 'drives[i]'
      continue
