Rename and resize images

• Application: bash

Fond of your new camera but can't put up with the terrible names? Do you want also to prepare them for publishing on the web? No problem, a simple bash script is what you need:

#!/bin/sh
counter=1
root=mypict
resolution=400x300
for i in `ls -1 $1/*.jpg`; do
        echo "Now working on $i"
        convert -resize $resolution $i ${root}_${counter}.jpg
        counter=`expr $counter + 1`
done

Save the script in a file called picturename.sh and make it executable with

chmod u+x picturename.sh

and store it somewhere in your path. Now, if you have a bunch of .jpg files in the directory /path/to/pictdir, all you have to do is to execute

picturename.sh /path/to/pictdir

and in the current directory you'll find mypict_1.jpg, mypict_2.jpg etc, which are the resized versions of your original ones. You can change the script according to your needs, or, if you're just looking for super-simple image resizing, try looking at the mogrify command with its -geometry parameter.
