“The script accepts the name of a program or package as an argument when you run it. This value is then referenced as “$1” (argument number 1). Everywhere the script says “$1”, it substitutes in the name of the package you gave it. The end result is the name being tried against a large number of software repositories and package managers, and hopefully, at least one of them will be appropriate and the program will be successfully installed.”
