You might see if your camera has another option. Mine (an Olympus 3030z) includes the date in the filename, and then a serial number which can either begin fresh after each SmartMedia disk is erased or installed fresh, or it can continue the serial number until it reaches 9999 and restart at 0000. > So it looks as though I can use chcase to change the file names > from what ever they be when downloaded into date order, for instance ? Well, with some difficulty. Ideally, it would extract the date information from the image file. I have a Perl script that I wrote that does this, but it's designed for my Olympus and probably wouldn't work with another brand or even model. I had to modify it when I moved up from Olympus 320z to 3030z. If you just wanted the timestamp from the file or the time you ran chcase to be reflected in the filename, it would be easier to do, but what format? For example, you can include `date` in your Perl script, but it gives a rather unwieldy string, like: Thu Sep 26 05:56:18 CST 2002 and with a fast computer they would likely all get the same date, including the second ;-) If you use `date +%y%m%d` you would get: 020926 which might be useful combined with the serial number. Maybe too many numbers, though. ;-) > my experimental folder:- > root/Desktop/mont > root]# cd /root/Desktop/mont > mont]# ls > DSCI0001.JPG DSCI0004.JPG DSCI0007.JPG DSCI0010.JPG DSCI0013.JPG > DSCI0002.JPG DSCI0005.JPG DSCI0008.JPG DSCI0011.JPG DSCI0014.JPG > DSCI0003.JPG DSCI0006.JPG DSCI0009.JPG DSCI0012.JPG > > chcase -x 'tr/DSC1*/dd/mm/yyyy'*.jpg > Now I don't ecpect that to work because for > one thing it will create a lot of files that may > possibly end up with the same name, or would it, > presumeably it would addopt the numerical progression > as well. No, that won't work at all. To begin with, the Perl tr/pattern1/pattern2/ structure only makes a literal translation of characters, replacing any character in pattern1 with its corresponding character in pattern2. Not what you want at all. And of course, you cannot use '/' to separate day, month, and year in a filename because the '/' is used to separate directories and files in the path. > What would be your thought here Jan, or maybe you have a better > suggestion. Why not just create a directory for each batch of photos you download, and put them into that. One directory would get unmanageable anyway. Then you can use chcase to change the names to something more manageable, but keep the serial numbers to differentiate files. For example, maybe make a directory called 0210 for 2002 October, and in it you put photos from a birthday party: chcase *.JPG chcase -x 's/dsci/bday/' *.jpg Hope this helps. -- Jan Wilson, SysAdmin _/*]; [EMAIL PROTECTED] Corozal Junior College | |:' corozal.com corozal.bz Corozal Town, Belize | /' chetumal.com & linux.bz Reg.
