um

um is a Python-based command-line assistant that uses GPT to turn plain-English questions into shell-command suggestions. It can index and search shell history, respond to corrections, suggest next actions from usage patterns, index files or websites, and create or reuse Terraform provisioning templates.

Practical overview

When it fits

Use um when you want command suggestions or command-history search without leaving the terminal, or when you want its documented Terraform template workflow.

Who it is for

  • Terminal users who want to look up shell commands using natural-language questions.
  • Developers and operations practitioners who want fuzzy or semantic search across command history.
  • Terraform users who want to create or reuse provisioning templates from the CLI.

Documented uses

  • Ask for a shell command by describing the task in plain English.
  • Find previously used commands through indexed history and reverse search.
  • Provide corrections or additional context while refining a command suggestion.
  • Request next-action suggestions based on usage patterns.
  • Index a file or website for assistant context.

Requirements & limits

The repository documents installation on Ubuntu, macOS through Homebrew, and through pip. The pip route requires Python 3.10 or later. The repository specifies a GPL-3.0 license.

  • The pip installation path requires Python 3.10 or later; the README also provides Ubuntu and Homebrew installation routes.
  • Extended reverse search is optional and documented as working only with Zsh.
  • The documented infrastructure-template workflow currently targets Terraform.
  • The repository describes the project as GPT-powered and provides a local runner command, but gives no further description of that runner in the README.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
