We can't see your scanner from here, please post your code. Photo or screenshot if you absolutely have to but we have to see it or we're just guessing.

If you're not in BASH, you don't get read -p.

Most shells should have read -r, you must be in a really old or minimal shell if you don't. Luckily -r isn't mandatory, it just prevents read from handling backslashes.

Also, be careful with spaces inside [ ] brackets. Each separate item must be separated by whitespace.

Code:
printf "Files will be overwritten, continue?"
read CONT
if [ "$CONT" = "y" ]; then
   mkdir /home/patient/backup-`gx125-svr`;
else
   exit;
fi

I don't know what gx125-svr is.

gx125-svr is my hostname

If you can't type it at a prompt and run it, you can't put it in backticks. Just /home/patient/backup-gx125-svr is fine if that's literally what it's called.

If you want to actually look up the hostname, use `hostname`, as that is actually a command. Try running it and see what it does.
