Looking for a small LLM for Linux command generation

I'm looking for a small LLM to act as a Linux command assistant. I will use llama.cpp.

use case:

- User asks in natural language. Model outputs only the shell command

- Should work well with no reasoning (for example, LFM 2.6 has forced reasoning)

- Fast, like ~4B at most, cause it's going to be on CPU

Example 1:
"replace string X with Y in file Z"

Example 2:

"stop and remove docker containers with X in the name"
