Shell script to find largest PNG files in directory recursively

The following shell script finds the largest PNG files in a directory recursively and prints their sizes in human-readable format:

find . -iname "*.png" -type f -exec du -h {} + | sort -rh | head -n

where:

• find . -iname "*.png" searches for all PNG (case-insensitive: .png or .PNG etc) files in the current directory (.) and subdirectories
• -type f ensures that only files are considered (not directories)
• -exec du -h {} + executes the du command on each found file, printing their sizes in human-readable format
• sort -rh sorts the output in reverse order by size
• head -n limits the output to the top n largest files
