I have photos from my mobile phone, an old Nokia 6021, and readily get them onto the PC. I wish to reorder them to be year, month and then day.
An alternative to filename based shell scripts and the rename command is to use jhead to rename them based on the date and time embedded in the exif jpeg header.
There were a number of suggestions, Russell and others came up with shell scripts, which have generic merit. i think that the one of Russell's that I tried had a small hiccup with unmatched brackets, and not quite sure where the opening one should have been. Craig came up with the perl based rename command, and his example worked a treat, and again is flexible for more than just photos. Your contribution is also very instructive, it has value in that it does not depend on the filenames having any commonality. I rate all of these as very useful and informative. Now I have another small question, i want to make copies of selected photos, but with a maximum size limit. I do have, and use, convert. I scan documents, and use convert to put the right way up, and convert the native scan format to jpeg. For the photos, I want to make them less than 250Mb. I will reread the man page, but there are so many options, and quite the implications.... It reminds me of trying to set up Xwindows in the earlier days, having to know the implications of the dot clock and the like, especially if you did not have the monitor details.
For example:
jhead -n'%Y%m%d-%H%M%S(%03i)' *.jpg
Will rename files matched by *.jpg to the format YYYYMMDD-HHMMSS(00#).jpg
Again, thanks to everybody. Regards, Mark Trickett
