From 971ed2bbdf61d07db6fcb54c3fde40fd8897158a Mon Sep 17 00:00:00 2001 From: teknium1 Date: Sun, 1 Feb 2026 10:02:34 -0800 Subject: [PATCH] Implement sudo support across terminal environments - Added support for sudo commands in local, Docker, Singularity, and SSH environments by introducing the `SUDO_PASSWORD` environment variable. - Updated terminal tool configurations in `.env.example` and `cli-config.yaml.example` to document the new sudo functionality. - Enhanced the command execution process to handle sudo commands gracefully, preventing hangs on interactive prompts and providing clear error messages when no password is configured. - Updated `README.md` to include instructions for using sudo support and SSH backend configuration. - Revised `TODO.md` to reflect the completion of the sudo feature and outline future enhancements. --- .env.example | 137 ++----------------------- README.md | 9 +- TODO.md | 27 +++-- cli-config.yaml.example | 25 +++++ cli.py | 2 + tools/terminal_tool.py | 218 ++++++++++++++++++++++++++++++++++++++-- 6 files changed, 276 insertions(+), 142 deletions(-) diff --git a/.env.example b/.env.example index ccd724bef..9f6f3d873 100644 --- a/.env.example +++ b/.env.example @@ -2,132 +2,17 @@ # Copy this file to .env and fill in your API keys # ============================================================================= -# LLM PROVIDER (OpenRouter) +# SUDO SUPPORT (works with ALL terminal backends) # ============================================================================= -# OpenRouter provides access to many models through one API -# All LLM calls go through OpenRouter -
