for file in *; do mv "$file" "$(echo $file | sed 's/-/_/g')"; done
To confirm that the files have been renamed correctly, you can use the ls command. Here's an example:

ls
This should output a list of files with snake case names instead of kebab case names.

In order to use this command in Arch Linux, you don't need to install any additional packages as zsh is already included with the system. However, if you don't have sed installed, you'll need to install it with the following command:

sudo pacman -S sed
Once sed is installed, you should be able to run the command without any issues.
