Sed Replace With Two Different Variable Values

Question

I want to replace old path variable to new one like this:

script_path=$(readlink -f "$0") #[/home/username/Desktop/script]
desktopfolder_old=/home/username/Desktop
desktopfolder_new=/home/username/NewOne
script_path_new=$(echo "$script_path" | sed -e "s/$desktopfolder_old/$desktopfolder_new/")

Because the bash script will be moved while it is running. But couldn't do it. What would it be like?

Those /s in the variables are going to totally mess up the sed "s/$var... after the var substitutions. The -e is also superfluous. Try instead:

script_path_new=$(echo "$script_path" | sed "s|$desktopfolder_old|$desktopfolder_new|")
