Thank you for providing an alternative zsh command to rename files from kebab case to snake case. Your command also achieves the same result by iterating over each file in the directory and using the sed command to replace hyphens with underscores in the file names.

As for the required packages, you are correct that zsh and sed are typically included in a standard Arch Linux installation and should not need to be installed separately. However, it's always a good idea to double-check and install them if necessary, using the commands you provided:

        sudo pacman -S zsh
        sudo pacman -S sed

These commands will install zsh and sed on your Arch Linux system if they are not already installed.
