I want to convert several jpg files into png files. As far as I know, one can use this command
mogrify -format png *.*
I have one problem, I have a lot of subfolders. Let's say a is my main folder and b,c and d are subfolders. The images are in the subfolders.
How can I convert all images without having to open every folder manually?
-> I would like to write a command that works, when I am in folder a, but works for all files in the subfolders.
Assuming you're in folder a the following might work for you
find . -name "*.jpg" -exec mogrify -format png {} \;
You can use the find command to get all the jpg files in all the subfolders and pass your command as an argument to find
