This bash script installs Yay, a package manager for Arch Linux, from its source on the Arch User Repository (AUR). It checks if the user is in their home directory and prompts for confirmation before proceeding. The script then removes any existing Yay installation, clones the Yay repository, builds and installs it, and cleans up temporary file…
