If you are going to use these commands on your own, make sure to run it from your home directory after placing the .dotfiles into there or you will need to replace './' in the command with the path to where the repo dotfiles are stored on your system.
The first command lists the files containing "/home/mehedi" and the second command lists where in each file needs to be updated.
Example below:
[kyle@Kyle-Laptop]$ grep -rnhl '../' -e "/home/mehedi"
.config/fastfetch/config.conf
.config/btop/btop.conf
.config/xfce4/panel/whiskermenu-8.rc
