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.
