for disk in $(lsblk -d -o name | grep -E '^sd|^nvme'); do

while IFS= read -r disk; do
-z "$disk" && continue
done < <(lsblk -d -o name | grep -E '^sd|^nvme')

# Bad: for disk in $(lsblk -d -o name | grep -E '^sd|^nvme'); do # Good: while IFS= read -r disk; do [[ -z "$disk" ]] && continue done < <(lsblk -d -o name | grep -E '^sd|^nvme')
