#   -type f - only search for files (not directories)
#   \( & \) - are needed for the -type f to apply to all arguments
#   -o - logical OR operator
#   -iname - like -name, but the match is case insensitive

find . -type f \( -iname \*.jpg -o  -iname \*.jpeg \) -print0 | xargs -0 mogrify -monitor -format heic
