Linux Command GPT (lcg)

This repo is forked from https://github.com/asrul10/linux-command-gpt.git

Generate Linux commands from natural language. Supports Ollama and Proxy backends, system prompts, different explanation levels (v/vv/vvv), and JSON history.

Installation

Build from source:

git clone --depth 1 https://github.com/Direct-Dev-Ru/linux-command-gpt.git ~/.linux-command-gpt
cd ~/.linux-command-gpt
go build -o lcg

# Add to your PATH
ln -s ~/.linux-command-gpt/lcg ~/.local/bin

Quick start

lcg "I want to extract linux-command-gpt.tar.gz file"

After generation you will see a CAPS warning that the answer is from AI and must be verified, the command, and the action menu:

ACTIONS: (c)opy, (s)ave, (r)egenerate, (e)xecute, (v|vv|vvv)explain, (n)othing

Explanations:

• v — short; vv — medium; vvv — detailed with alternatives.

Clipboard support requires xclip or xsel.

Environment

• LCG_PROVIDER (default ollama) — provider type: ollama or proxy
• LCG_HOST (default http://192.168.87.108:11434/) — base API URL
• LCG_MODEL (default hf.co/yandex/YandexGPT-5-Lite-8B-instruct-GGUF:Q4_K_M)
• LCG_PROMPT — default system prompt content
• LCG_PROXY_URL (default /api/v1/protected/sberchat/chat) — proxy chat endpoint
• LCG_COMPLETIONS_PATH (default api/chat) — Ollama chat endpoint (relative)
• LCG_TIMEOUT (default 300) — request timeout in seconds
• LCG_RESULT_FOLDER (default ~/.config/lcg/gpt_results) — folder for saved results
• LCG_RESULT_HISTORY (default $(LCG_RESULT_FOLDER)/lcg_history.json) — JSON history path
• LCG_PROMPT_FOLDER (default ~/.config/lcg/gpt_sys_prompts) — folder for system prompts
• LCG_PROMPT_ID (default 1) — default system prompt ID
• LCG_JWT_TOKEN — JWT token for proxy provider
• LCG_NO_HISTORY — if 1/true, disables history writes for the process
• LCG_SERVER_PORT (default 8080), LCG_SERVER_HOST (default localhost) — HTTP server settings

Flags

• --file, -f read part of prompt from file
• --sys, -s system prompt content or ID
• --prompt-id, --pid choose built-in prompt (1–5)
• --timeout, -t request timeout (sec)
• --no-history, --nh disable writing/updating JSON history for this run
• --debug, -d show debug information (request parameters and prompts)
• --version, -v print version; --help, -h help

Commands

• models, health, config
• prompts list|add|delete
• test-prompt <prompt-id> <command>
• update-jwt, delete-jwt (proxy)
• update-key, delete-key (not needed for ollama/proxy)
• history list — list history from JSON
• history view <index> — view by index
• history delete <index> — delete by index (re-numbering)
• serve-result — start HTTP server to browse saved results (--port, --host)

Saving results

Files are saved to LCG_RESULT_FOLDER (default ~/.config/lcg/gpt_results).

• Command result: gpt_request_<MODEL>_YYYY-MM-DD_HH-MM-SS.md

  • # <title> — H1 with original request (trimmed to 120 chars: first 116 + ...)
  • ## Prompt
  • ## Response

• Detailed explanation: gpt_explanation_<MODEL>_YYYY-MM-DD_HH-MM-SS.md

  • # <title>
  • ## Prompt
  • ## Command
  • ## Explanation and Alternatives (model: <MODEL>)

History

• Stored as JSON array in LCG_RESULT_HISTORY.
• On new request, if the same command exists, you will be prompted to view or overwrite.
• Showing from history does not call the API; the standard action menu is shown.
