The command arch -arm64 "${command}" is used to execute a specific program or command ("${command}") specifically for the ARM64 architecture on macOS.

Here's an explanation of each part of the command:

• arch: It is a command-line utility in macOS that allows you to execute commands or programs for a specific architecture. It determines the architecture of the current system and runs the specified command with the appropriate architecture.

• -arm64: It is an argument passed to the arch command, specifying that the specified command should be executed for the ARM64 architecture. The ARM64 architecture is commonly used in Apple Silicon-based Macs and iOS devices.

• "${command}": It represents the command or program that you want to execute with the specified architecture. The "${command}" is a placeholder, and you should replace it with the actual command that you want to run. For example, if you want to run the ls command with ARM64 architecture, you would replace "${command}" with ls.

By using the arch -arm64 command, you can ensure that a specific program runs using the ARM64 architecture, even if you are using a system that supports multiple architectures.
