Bash4LLM is a single-file Bash wrapper for interacting with LLMs from the terminal. I created it because I wanted something simple that worked without installing Python, Node, or any other runtime.It uses only Bash, curl, and jq. You can send prompts, start a small chat, process files line by line, stream output, and save session metadata in JSON format.I tried to make it safe and predictable: no use of the system /tmp, no use of eval. Groq is supported by default, and other providers can be added with dedicated Bash scripts in the extras/providers/ folder.Example: echo "explains the command: ls -l" | ./bash4llm

Competitors mentioned: llayer (bash/curl/jq wrapper for Ollama), Python-based LLM tools, Ollama
Concerns raised: Code is verbose and redundant with too many lines for functionality, LLM-generated code quality is poor and harder for models to audit, Bash portability issues (macOS old bash, BSD coreutils differences), Performance slower than Python despite claims, Only free LLM plans used, limiting capabilities
Feature requests: More concise code generation and prompting, Reduce verbosity and redundancy in implementation, Better cross-platform portability documentation
