The command "yay -Sua" is used on Arch-based Linux systems and is a combination of multiple options:
-
"yay" is the name of an AUR (Arch User Repository) helper tool, which is used to search and install software packages from the AUR. It simplifies the process of installing applications that are not available in the official repositories.
-
"-S" is a flag used with "yay" to specify that you want to install a package. It is followed by the package name you want to install.
-
"-u" is another flag used with "yay" to update all installed packages. When used in combination with "-S", it updates the package database before installing the requested package.
-
"-a" is a flag used with "yay" to update all AUR packages.
So, when you run the command "yay -Sua", it performs a system upgrade by updating all installed packages, including AUR packages, and then it installs the specified package if it is available in the AUR.
