back from nicest time of year and want to share your pictures? first step is often the most cumbersome – sorting pics by date! even more, if you and friends brought two, three, even a handful cameras. The only obvious solution here: rename your pics according to the date and time taken. the following can accomplish this (equally on linux, windows, mac) within seconds:
jhead -n%Y%m%d-%H%M%S *.JPG

jhead is a standalone Package, and it is available as a Windows executable, too.

story about former IBM CEO Thomas Watson: When once one of his employees did badly wrong, the company lost $ 600,000. A journalist wondered, when the guy would get fired.
