QUESTION: Is there anything so Sage can be made to automatically execute commands on startup?
ANSWER: Yes, just make a file $HOME/.sage/init.sage and it will be executed any time you start sage.Thu, 19 Jan 2012 09:43:38 +0100https://ask.sagemath.org/question/8646/preload-defined-functions-for-later-use/?answer=13151#post-id-13151Comment by Josso for <p>Sure.
