6. CLI

MYRaf also includes a command-line interface (CLI), which, while capable of performing basic operations, does not fully encompass the extensive functionalities of the MYRaf library. Additionally, the CLI lacks the computational power and flexibility inherent to Python programming.

The MYRaf CLI is invoked using the command im. This command is further subdivided into various subcommands, each of which has its own set of positional and optional arguments tailored to specific tasks.

The CLI proves particularly useful for executing simple operations directly from the terminal, providing a convenient alternative for certain tasks.
