A bash script to check the dimensions of images recursively, using getopts and find.
img_checker.sh [OPTION...]
OPTIONS:
-d <dir_name>, specify the directory inside which the script will loop
-l <file_name>, the script will log the images that aren't correct into <file_name>
-m <min_dim>, the script will check if the dimension of the images are beyond the minimum <min_dim>
-M <max_dim>, the script will check if the dimension of the images are beyond the maximum <max_dim>
-s, the script will check if the images are squared (i.e. NxM with N == M)
-r, rename each file with the name of its parent folder, followed by its index inside the directory
example: /Pokémon/Voltorb/cbahf4kasdm3.jpg -> /Pokémon/Voltorb/Voltorb1.jpgDirectory structure:
./Pokémon/
|
+-- Bulbasaur/
| |
| +-- img1.jpg, img2.png, [...]
|
+-- Charmander/
| |
| +-- img1.jpg, img2.png, [...]
|
+-- Squirtle/
| |
| +-- img1.jpg, img2.png, [...]
|
[...]
Task 1: Find every non-square image in 'Pokémon/' subdirectories and log their path to 'log.txt'.
user@hostname: ~$ ./img_script -d Pokémon/ -s -l log.txt'-d Pokémon/' tells the script we want to check all the images in Pokémon/ subdirectories
'-s' tells the script we want to check if the images are squared
'-l log.txt' tells the script to log the incorrect images to the file log.txt
Task 2: Find every image, in 'Pokémon/' subdirectories, which height or width is less than 250, and also rename them with the name of their parent folder.
user@hostname: ~$ ./img_script -d Pokémon/ -m 250 -r'-d Pokémon/' tells the script we want to check all the images in Pokémon/ subdirectories
'-m 250' tells the script we want to check if the minimum of the dimension of the images is 250
'-r' tells the script we want to rename each image with its parent folder
ImageMagick package must be installed.
- Fix filename with spaces bug;
- Fix the rename bug which deletes some files if they're already named in the same way;
- Add extension check (specify a list of extensions, e.g. '.jpg, .png');
