save and rerun lists of sage commands

make a text file with the extension .sage

http://doc.sagemath.org/html/en/tutor...

Here are several options:

• as @FrédéricC says, create a file with a .sage extension containing your commands, say my_file.sage, and then while running Sage, use the command %attach /path/to/.../my_file.sage. Using %attach means that if you edit the file while Sage is running, it will automatically reload it, re-executing all of the commands.

• if you don't mind a non-text file, you can save your Sage session: see http://doc.sagemath.org/html/en/tutor.... (I've never actually done this, but I use %attach all the time.)

You can use

%history -f my_session.sage

This saves all the sage commands typed during your session in the text file my_session.sage. Then, you can load this file in a new Sage session by

%load my_session.sage

In the Jupyter notebook, this loads all the saved commands in a single cell. In the Sage console, you will have to press Enter at the prompt ...: to rerun the commands and possibly enter n to the question

File u'my_session.sage' exists. Overwrite?

This occurs because the %history command has been saved in the file my_session.sage and therefore is run again when you load the file.

An alternative is to use %attach as described in @John_Palmieri's answer.
