I would like to know if there's a command that can tell me how much storage are the .jpg files (for example). Something like if I do find / -iname "*.jpg" which can add the size of each file found and output a total.

  • Output the find results in a file an run du -s on its content. – Julie Pelletier Jul 2 '16 at 20:05
find ./path/to/your/drive -type f -name '*.jpg' -exec du -ch {} +

Or much faster

find /path/to/your/drive -name "*.jpg" -print0 | du -ch --files0-from=-

Or simply,

du -ch /path/to/your/drive/*.jpg | grep total

Or with help of awk,

find /path/to/your/drive -iname "*.jpg" -ls | awk '{total += $7} END {print total}'

On my system file size shows on seventh field, if it's different for you then adjust accordingly.

As requested by OP in comment, if you want to find all images from a directory and total size you can use this command (suggested by @Stéphane Chazelas)

 find . -type f -exec file --mime-type {} + | sed -n 's|: image/[^[:blank:]]*$||p' | tr '\n' '\0' | du --files0-from=- -hc


 du -shc $(find . -name '*' -exec file {} \; | grep -o -P '^.+: \w+ image' | cut -d':' -f1) | grep total

    That will only give the individual sizes of each file. – Julie Pelletier Jul 2 '16 at 20:17

  • Thank you Rahul, I just wonder how can I make it work with: find . -name '*' -exec file {} \; | grep -o -P '^.+: \w+ image' which basically looks for all images not just jp*g files. – VaTo Jul 2 '16 at 20:39

    @Saul, find . -type f -exec file --mime-type {} + | sed -n 's|: image/[^[:blank:]]*$||p' | tr '\n' '\0' | du --files0-from=- -hc – Stéphane Chazelas Jul 2 '16 at 20:46
  • @Saul see updated answer – Rahul Jul 2 '16 at 21:08

As an alternative, you can do this using only POSIX:

find . -type f -name "*.jpg" -exec du -sk {} \; |
  awk 'BEGIN{total=0};{total += $1}; END{printf "%.3f MB\n", total / 1024}'
