Sort images by resolution

When recovery of files done and you restored images with help of a post recovery tasks script then it could be wise to sort images by the resolution. This will help to sort the photos you made, webcam images or any other images into the folders by the resolutions, most of them are often using the same related image resolutions.

Note: To speed up access to the recovered or restored files you can use shake utility to defragment them.

Collect info about images

Warning: You must have installed the feh program before running the script.

Note: To speed up collecting info about images you can skip duplicate images by use a list of non duplicate files but you will also need to remove mime type check in this script and add check files by extension instead.

collect-info-about-images.sh

#!/bin/bash
if [ 'XX' != 'XX'"$1" ]; then 
 if [ -f "$1"  ]; then
# mime part start
  IsIt=$(file "$1" --mime-type -b);
  NeedImageOnly="ItIs_"${IsIt/'/'*/}
   if [ "$NeedImageOnly" == "ItIs_image" ] ; then
# mime part end
ImageInfoFEH=($(feh -l "$1"))
IfDamaged=${?}
ImageType=${ImageInfoFEH[9]}
   Height=${ImageInfoFEH[11]}
    Width=${ImageInfoFEH[10]}
   if [ "$IfDamaged" != '0'  ]; then 
    echo "$1" "Damaged" "${IfDamaged}";
   fi;
    echo "$1"'|'W'|'$Width'|'H'|'$Height'|'Format'|'$ImageType'|'Errors'|'$IfDamaged'|' >> collect-info-about-images.txt
# mime part start
  fi
# mime part end
   else
    echo The « "$1" » is not a valid file name.
  fi
 else
  ScriptsName=${0##*/}
   find -type f -exec sh -e "./$ScriptsName" "{}" \;
  #find -type f  -name "*.jpg" -o -name "*.gif" -o -name "*.png" -exec sh -e "./$ScriptsName" "{}" \;
fi

The $IfDamaged variable contains an exit status code returned by feh.

You can also install to check integrity of "PNG, JNG or MNG" and/or jpeginfo^AUR and use output of errors in the $IfDamaged variable or modify script to skip adding of damaged files into a collect-info-about-images.txt file.

Example of check resuslt:

Example of jpeginfo^AUR check result:

Note: The jpeginfo^AUR utility cannot scan directories recursively but can read filenames from a file created by find -type f -name "*.jpg">>FileWithPathTo-images.txt, calculate their md5sums and has an option that makes it able to remove damaged image files.

To extract necessary data from a string in a script is better to use an expression instead of an extern program as sed or to make a script work a little faster, e.g.

The collect-info-about-images.sh script generates data about images by pattern:

full path to image|Width|size|Height|size|Format|type of image|Errors|exit code by feh|

Example:

Sort images by resolution

This script creates folders based on the resolution. You can set your limitations about how many files should be in each folder and how many sub-directories in a base file type named folder. When limit is reached a new number in the order will be added to a directory name for creation. If you have a really huge amount of files and do not want to overload a single folder with all of them then you can also add your own counters for a new sub-folders after the base destination variable , just look out for quotes " to be in the begin and end of a whole destination path. It use to be much more easier to browse folders with a limited amount of images, thumbnails loads much faster and to remember or add to favorite a folder number/name instead of trying to find once more same image in an overloaded folder out of probably thousand images there.
