CLI Flag Generator

Generates conventional command-line flags with short and long forms

Complete guide · 4 min

About this generator

A CLI tool where `-v` means something unexpected, or where `--force` is missing and users have no escape hatch, feels wrong immediately. Established flag conventions exist because they are already in users' muscle memory. This tool returns a shuffled set of command-line flags in the standard short-and-long form. The only input is how many you want, from 1 to 10 (14 in the pool). Each entry pairs a single-letter short flag with a long flag and a one-line description, following POSIX and GNU conventions: `-h, --help`, `-v, --version`, `-V, --verbose`, `-n, --dry-run`, `-f, --force`, `-o, --output FILE`, `-c, --config PATH`, `-r, --recursive`, `-w, --watch`, `-p, --port NUM`, `--no-color`, and more. Keep the meanings exactly as shown and your CLI will feel familiar from the first run.

How to use

  1. Choose how many CLI flags you want.
  2. Generate a set that fits your tool.
  3. Keep each flag's meaning conventional.
  4. Drop them into your help screen and parser.

Use Cases

  • •Designing a command-line interface
  • •Writing a clear help screen
  • •Documenting a CLI tool
  • •Keeping flag meanings conventional
  • •Scaffolding argument parsing

Tips

  • →Provide both a short and a long form.
  • →Keep conventional meanings like -h and --dry-run.
  • →Use --no- prefixes to disable default-on options.
  • →Write a one-line description for every flag.

FAQ

why provide both short and long flag forms

Short flags like `-v` are fast to type interactively; long flags like `--verbose` are self-documenting in shell scripts and documentation. Providing both serves quick manual use and readable automation without forcing a choice.

are these flag meanings considered standard

Yes. `-h` for help, `-v` for version, `--dry-run` for a safe preview, and `--force` to skip confirmations are widely established. Deviating — for example using `-v` for verbose instead of version — confuses users who already know them.

when should I use a --no- prefix

Use `--no-<option>` to disable a boolean feature that is on by default. `--no-color` is the canonical example: color output is the default, and the flag turns it off. This pattern is immediately recognisable to CLI users.
