The command to do this used to be called "detach". It has mysteriously completely
vanished from Sage since when I wrote it! It's in the notebook still, but it isn't available
from the command line anymore.
Anyway, I've reported this as trac #
In the meantime you can work around this problem as illustrated below:
sage: sage: attach example.sage
This is a simple SAGE example script.
...
sage: import sage.misc.interpreter
sage: sage.misc.interpreter.attached
{'/home2/sage/build/sage-2.10.alpha4/example.sage': 1197908255.0}
sage: del sage.misc.interpreter.attached['/home2/sage/build/sage-2.10.alpha4/example.sage']
sage: attached_files()
