I thought that in Nautilus there was a way to apply the same bash
command to every highlighted file. Looking around, though, I can't
seem to find it. Which is probably why I hate file managers.
If you know that a specific group of pictures were taken between,
for example, 7PM & 10PM on thursday, you could, after renaming them
with jhead, you could do this:
for i in `ls -1 20060330-19??.jpg 20060330-2[01]??`; do
b=`basename $i .jpg`
mv $i ${b}_Marys_bday_party.jpg
done
(Yes, I could embed the basename command in the mv statement, but I
find this easier to read.)
