Hi
Thanks so much for your assistance and the incredibly quick reply.
Fortunately, We have a lot of old laptops that are going to be sent to the recyclers soon so I can test the USB boot stick on those. If I "brick" them it doesn't matter.
Regarding persistence:
I started with the FAQ at
http://tinycorelinux.net/faq.html#pendrivesIt says:
To find the UUID of a device use the command blkid
blkid -s UUID /dev/sda1
You can mount devices by UUID with the mount command, e.g,
mount -U 4773-DFE2
You can now specify the device to be used by UUID as follows:
tce=UUID=4773-DFE2 home=UUID=4773-DFE2 opt=UUID=4773-DFE2 restore=UUID=4773-DFE2
So I did that.
Once booted and at the $ prompt, the current folder is inside the /home directory. If I make a folder in there it's gone after I restart. I cannot find the tce folder that I can see is on USB stick if I look at it in windows (which I assume is where I put my data so it does not get lost after a restart?).
I have also tried booting and then at the "boot:" prompt I pressed F2 then I typed:
mc tce=sda1 home=sda1 opt=sda1 restore=sda1
but once again any folder I create in /home is gone after a restart.
Sorry I don't understand the bootloader stuff. I made a Mint Linux boot stick and it boots under UEFI bios, but into a desktop environment. I can see some grub folders on that stick when viewed from windows. But what I really want is just a small simple quick linux like Tiny Core that boots to a shell where I can run some simple awk scripts and retain the data.
