Look at the code there:
-if [[ "$1" =~ "--notebook="* || "$1" =~ "-n="* || "$1" =~
"-notebook="* ]]; then
+if [[ "$1" =~ ^--notebook=.* || "$1" =~ ^-n=.* || "$1" =~
^-notebook=.* ]] ; then
sage-cleaner &>/dev/null &
exec sage-notebook "$@"
fi
It's depressing to be parsing the command line options to Sage via
shell expressions... (It's my fault, I know.)
