How to create a permanent Bash alias on Linux/Unix

I need to create a bash shell alias named update as follows:
alias update=‘sudo – sh -c "/root/bin/chk_disk && dnf update’
However, this update alias gets removed after I reboot the Fedora Linux box. How do I create a permanent Bash alias on a Fedora Linux or Unix-like system?
