F# in Action: A Revised Edition of Get Programming with F#
A console application is a program that interacts with users or other processes through a text-based terminal.
- How it is used
- Turns explored F# functions into terminal programs that collect input, invoke domain logic, and print results.
- How deep it goes
- Walks through creation, source-file inclusion, dependency ordering, execution, and a C# project reference; it does not detail argument parsing.
- Examples
- Uses Hello World scaffolding, a car-driving program that prints remaining gas, and an F# application consuming a C# Person class.
- What you can do after
- Build it from scratch as an F# console application, organize its files, run it, and reference a C# project.

Go in Practice, Second Edition
A console application is a program operated through a command-line text console by supplying commands, options, and arguments.
- How it is used
- Uses textual commands, options, flags, and arguments as the user interface for systems, utilities, and operational programs.
- How deep it goes
- Demonstrates standard-library parsing, framework-based commands, subcommands, configuration, and service lifecycle, but not GUI construction.
- Examples
- Uses a flagged Hello World command, Cobra-based greeting code, and a calculator with arithmetic subcommands.
- What you can do after
- Build it from scratch with Go's flag package or a command-line framework, including flags, help output, commands, and subcommands.

Go by Example
A command-line tool is a software program operated through textual commands in a shell or terminal.
- How it is used
- Automates repetitive tasks and runs programs through required arguments and optional flags.
- How deep it goes
- Explains arguments, flags, os, flag, custom flag types, and validation, stopping short of detailed parser internals.
- Examples
- Uses the HIT HTTP performance tool, terminal invocations, performance summaries, and exercises building related tools.
- What you can do after
- Build it from scratch with Go's os and flag packages, custom flag types, and input validation.
