Finds all corrupted jpeg files in current directory and its subdirectories. Displays the error or warning found. The jpeginfo is part of the jpeginfo package in debian. Should you wish to only get corrupted filenames, use cut to extract them : find ./ -name *jpg -exec jpeginfo -c {} \; | grep -E "WARNING|ERROR" | cut -d " " -f 1 Show Sample Output

converts RAW files from a Nikon DSLR to jpg for easy viewing etc. requires ufraw package

Yes, You could do it in the GIMP or even use Inkscape to auto-align the clones, but the command line is so much easier. NOTE: The +clone and -clone options are just to shorten the command line instead of typing the same filename eight times. It might also speed up the montage by only processing the image once, but I'm not sure. "+clone" duplicates the previous image, the following two "-clone"s duplicate the first two and then the first four images. NOTE2: The -frame option is just so that I have some lines to cut along. BUG: I haven't bothered to calculate the exact geometry (width and height) of each image since that was not critical for the visa photos I need. If it matters for you, it should be easy enough to set using the -geometry flag near the end of the command. For example, if you have your DPI set to 600, you could use "-geometry 800x1200!" to make each subimage 1⅓ x 2 inches. You may want to use ImageMagick's "-density 600" option to put a flag in the JPEG file cuing the printer that it is a 600 DPI image. BUG2: ImageMagick does not autorotate images based on the EXIF information. Since the portrait photo was taken with the camera sideways, I made the JPEG rotate using jhead like so: jhead -autorot 2007-08-25-3685.jpg

Resizes all images in the curent directory to x resolution. It is better than `mogrify -resize *.jpg` because of independence from extension of image (e.g. .jpg and .JPG) (: Show Sample Output

This checks jpeg data and metadata, should be grepped as needed, maybe a -B1 Warning for the first, and a -E "WARNING|ERROR" for the second part....

This command takes all CR2 files in the current directory and convert them into JPG

The “predictive capture” feature of Sony's Xperia camera app hides the date stamp deeply inside the filename. This command adds another date stamp at the beginning of the filename. Show Sample Output

For each *.jpg or *.JPG file in the current directory, extract the date the photo was taken from its EXIF metadata. Then replace the date stamp, which is assumed to exist in the filename, by the date the photo was taken. A trick from https://unix.stackexchange.com/a/9256 is used to split the date into its components. Show Sample Output

Yes, You could do it in the GIMP or even use Inkscape, but the command line is so much easier. This is a new version of a previous command fixing some things complained about.
