CLI Modes

The Fabric CLI supports two modes: command-line and REPL (interactive). The active mode is determined automatically at runtime — no configuration is required.

Command-Line Mode

Command-line mode is best suited for scripted tasks, automation, or when you prefer running single commands without a persistent prompt.

Invoke any command directly from your terminal with the fab prefix:

fab ls /
fab get /myworkspace.Workspace/mynotebook.Notebook

REPL Mode

REPL mode provides a shell-like interactive environment. Run fab without any arguments to enter REPL mode:

fab

Upon entering REPL mode, you see a fab:/$ prompt. Commands are executed one by one without needing to type fab before each command:

fab:/$ ls
fab:/$ cd myworkspace.Workspace
fab:/myworkspace.Workspace$ get mynotebook.Notebook
fab:/myworkspace.Workspace$ quit

Type help for a list of available commands, and quit or exit to leave REPL mode.

Switching Between Modes

There is no explicit mode switch command. The mode is determined by how you invoke the CLI:

• Command-line mode — run fab <command> with one or more arguments.
• REPL mode — run fab with no arguments.
