Comment:
Ahem, what if Sage doesn't start? Then we get no date...
So you could either do something like
{{{
#!sh
echo "[`date +'%Y-%m-%d %H:%M:%S'`]" \
"`sage --version | sed -n -e '/Version/s/^[ |]\+//;s/[ |]\+$//p'`." \
| tee -a "$SAGE_ROOT"/start.log
spkg/pipestatus "sage -c \"print 'Yes, Sage starts.'\" 2>&1" "tee -a
'$SAGE_ROOT'/start.log"
}}}
or, directly,
{{{
#!sh
echo "[`date +'%Y-%m-%d %H:%M:%S'`]" \
"`sed -n -e '/Version/s/^[ |]\+//;/Version/s/[ |]\+$//p'
"$SAGE_LOCAL"/bin/sage-banner`." \
| tee -a "$SAGE_ROOT"/start.log
spkg/pipestatus "sage -c \"print 'Yes, Sage starts.'\" 2>&1" "tee -a
'$SAGE_ROOT'/start.log"
}}}
(`sage --version` is currently broken w.r.t. the removal, so you could
actually move the `sed` command to `sage-sage`.)
or use `sage --python -c 'your favourite Python code'` for printing the
date and Sage's version ('''without''' importing `sage.*`).
