I have a subdirectory called "Backups" in my home directory and run
the
following bash shell command (actually, it's in my crontab):
cd ~/Backups/ && mkdir sage_notebook.`date +\%Y.\%m.\%d` && cd
sage_notebook.`date +\%Y.\%m.\%d` && for x in ~/.sage/sage_notebook/
worksheets/admin/*/worksheet.txt ; do mkdir "`echo "$x" | sed 's/[^0-9]
*\([0-9][0-9]*\)\/worksheet\.txt/\1/g'`" ; done && for x in ~/.sage/
sage_notebook/worksheets/admin/*/worksheet.txt ; do cd "`echo "$x" |
sed 's/[^0-9]*\([0-9][0-9]*\)\/worksheet\.txt/\1/g'`" ; cp "$x" . ;
cd .. ; done && for x in */worksheet.txt; do y=`echo "$x" | sed 's/\
([0-9][0-9]*\)\/worksheet\.txt/\1/g' | sed 's/^[0-9]$/0&/g'` ; z=`head
-n1 "$x"` ; echo "$y $z" >> contents.txt ; cat contents.txt | sort >
contents.txt ; done && cd .. && tar -cf sage_notebook.`date +\%Y.\%m.\
%d`.tar sage_notebook.`date +\%Y.\%m.\%d` && bzip2 sage_notebook.`date
+\%Y.\%m.\%d`.tar && /bin/rm -r sage_notebook.`date +\%Y.\%m.\%d`
William's solution is obviously simpler (and betrays less neurosis
about
economizing on disk space). If I've understood him correctly, I'm not
losing anything vital by discarding all but the worksheet.txt files.
For other UNIX shells you might need to change the syntax slightly,
and
if you have more than 100 sage worksheets, you might want to edit the
"sed 's/^[0-9]$/0&/g'" command.
Sincerely,
Greg
