Original GitHub issue: https://github.com/ollama/ollama/issues/7405

I'd like to be able to set the system prompt from the call to ollama in my shell, rather than in the conversation. For example:

ollama run llama3.1 --system="Your nickname is 'Grass' now"

...or...

ollama run llama3.1 -s "system" "Your nickname is 'Grass' now"

With this ability, I could set up aliases in my shell profile so that I can run system-prompt-customized versions of a model with a single command.

alias grass="ollama run llama3.1 --system=\"Your nickname is 'Grass' now\""

It'd be even better if I could also specify a path to a text file with a system prompt (e.g. ollama run llama3.1 --system-file="~/system_prompts/grass.txt", but that wouldn't be necessary.

This is unique from #807, whose fix only works in the conversation.
