Write a simple script that will automatically rename a number of files. As an example we want the file *001.jpg renamed to user defined string + 001.jpg (ex: MyVacation20110725_001.jpg) The usage for this script is to get the digital camera photos to have file names that make some sense.
An example to help you get off the ground.
for f in *.jpg; do mv "$f" "`echo $f | sed s/IMG/VACATION/`"; done
In this example, I am assuming that all your image files begin with "IMG" and you want to replace "IMG" with "VACATION".
The shell automatically evaluates
*.jpg to all the matching files.
The second argument of
mv (the new name of the file) is the output of the
sed command that is replacing "IMG" with "VACATION".
