[Digikam-users] Thank you!

John asked about the two tools I used for my image collection 
restore/rename. One was digikam of course. The other is a commandline 
shell script that uses exif_tool:

http://www.sno.phy.queensu.ca/~phil/exiftool/

It's available for Win/Mac/*Nix. I'm using Linux (kubuntu 11.10) and the 
script below is what uses exif_tool and a bit of *nix magic. The gist of 
it is using output from exif_tool

exiftool -S -d "%Y/%m/%d/DSCN_%Y%m %dT%H%M%S" -EXIF:DateTimeOriginal $file

parsed through awk

awk '{print $2}

to isolate just the date/time output, which is then added to a string to 
form a filename path:

$HOME/Pictures/<awk_output>

which is assigned to a variable DEST.

That variable is the new path/filename. The install command is what 
actually renames the input file and does the move. If a file already 
exists with the name, the install command will not overwrite the 
existing file, but will append ~#~ to the end fo the file being moved, 
with # replaced the a real number.

The shell script is very basic and could with a bit of work be more 
elegant but it is functional and at present I'd rather just use it and 
futz with it. If you're familiar with using commandline tools like this 
in the Linux world just copy between the <quote></quote> to a file, set 
the file executable (chmod +x <filename>), and put it where it can be 
found (somewhere in the PATH env variable paths, e.g., /usr/local/bin). 
You can remove the # before set -x and the script will output what it's 
doing as it does it):
