Bhoot Shell: My Terminal Is Haunted, and the Ghost Runs on Local Gemma

Description and use

The script automatically reads recent terminal commands, generates eerie commentary with a local Gemma 4 model, and whispers it via ElevenLabs, keeping secrets local.

Problem

A terminal user wants an automated, spooky feedback loop that reads recent shell commands, generates eerie commentary, and plays it aloud without exposing sensitive data.

Outcome

The script delivers a fully automated haunted‑terminal experience: it reads recent commands, generates context‑aware spooky lines in Hindi or English, and whispers them aloud, all while keeping secrets local.

Workflow

• Read the most recent shell history from either Git Bash (~/.bash_history) or PowerShell PSReadLine history file.
• Apply a regex pass to mask tokens, bearer keys, secret keys, and user:pass URLs.
• Send the masked commands to the local Gemma 4 model (gemma4:e4b) via Ollama on 127.0.0.1, with a prompt that casts the model as a ghost and requires mention of at least one command.
• Receive the model’s one‑two line eerie reply, send it to ElevenLabs TTS (eleven_multilingual_v2) to generate an MP3, and play it with ffplay or the system’s default player.

Evidence

It reads the last five commands you typed, a local Gemma model writes one or two eerie lines about them, and ElevenLabs whispers them through your speakers.

The ghost never repeats itself.

Gemma 4 gave me silence. My first full run took 40 seconds and returned an empty string. Adding one field fixed it: "think": false.

Source

Node's fetch tried IPv6 ::1 first, and Ollama listens on IPv4. Hardcoding 127.0.0.1 fixed it.
