Two questions: (1) I'm having a hard time with this script. I couldn't find the SAGE_SERVER set in your new script, so added it as follows: Create a file sage-in-ipython, and run chmod a+x run-sage: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ #! /bin/bash # Once Ipython starts, please type # In [1]: from sage.all import * # to start Sage. export SAGE_ROOT=/home/wdj/sagefiles/sage-3.0.4.rc0 export SAGE_SERVER="http://www.sagemath.org/"; export SAGE_LOCAL=$SAGE_ROOT/local export DOT_SAGE=~/.sage/ export PATH=$SAGE_ROOT/local/bin:$PATH export LD_LIBRARY_PATH="$SAGE_ROOT/local/lib/openmpi:$SAGE_ROOT/local/lib/:" export PYTHONPATH="$SAGE_ROOT/local/bin:$SAGE_ROOT/local/lib/python2.5/site-packages/setuptools-0.6c8-py2.5.egg:$SAGE_ROOT/local/lib/python2.5/site-packages/SQLAlchemy-0.4.3-py2.5.egg:$SAGE_ROOT/local/bin:$SAGE_ROOT/local/lib/python:$SAGE_ROOT/local/lib/python25.zip:$SAGE_ROOT/local/lib/python2.5/plat-linux2:$SAGE_ROOT/local/lib/python2.5/lib-tk:$SAGE_ROOT/local/lib/python2.5/lib-dynload:$SAGE_ROOT/local/lib/python2.5/site-packages:$SAGE_ROOT/local/lib/python2.5/site-packages/IPython/Extensions" ipython ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Now, it says sage cannot be found: [EMAIL PROTECTED]:~/sagefiles/sage-3.0.4.rc0$ ./sage-in-ipython Python 2.5.2 (r252:60911, Jul 7 2008, 23:27:12) Type "copyright", "credits" or "license" for more information.

(2) If this was to be run from SAGE_ROOT (ie, /home/wdj/sagefiles/sage-3.0.4.rc0 in my case), could I replace the line export SAGE_ROOT=/home/wdj/sagefiles/sage-3.0.4.rc0 by export SAGE_ROOT=. and have the same effect? This would be independent of the user's setup and allow the script to be distributed with sage, if William and other developers wanted to do so.
