shred command all disks

Question

I have a couple of computers that have multiple drives in them. I have Ubuntu on a USB drive that and right now using the shred option I need to manually run the shred command for each HDD/SSD myself.

Is it possible that it does that shred automatically for all the drives that it has, except for the USB that Ubuntu is running from?

that way you know the disk letters already is there not a script that finds these automaticly — Klaas Idjdk, Aug 09 '19 at 09:59
get the disks **list** with something like `lsblk -S | grep disk | cut -d " " -f 1` then run the referred `for` loop against this **list** — cmak.fr, Aug 09 '19 at 10:53

Shred all physical disks?

Get the disks list with something like lsblk -S | grep disk | cut -d " " -f 1 then run the a loop against this list

#!/bin/bash
## get disks list
DisksList=$(lsblk -S | grep disk | cut -d " " -f 1)
## Loop from https://askubuntu.com/a/786171/77093
for d in $DisksList ; do
    ## shred --your-options-here /dev/$d 2>&1 >shred.$d.log &
    # example of a shred command options, no log, one thread
    shred -vfz -n 1 /dev/$d
done
