Sum files of certain extension in given directory

echo $(find <directory> -name '*.<extension>' -exec du -s {} \; | tee $(tty) | cut -f1 | tr '\n' '+') 0 | bc
Also shows files as they are found. Only works from a tty.

What Others Think

Hmm... On Fedora 17 this only displays the total. If I change the tee command to "tee /dev/pts/0" I get the expected output. You can simplify all the maths with awk: find <directory> -name '*.<extension>' -exec du -s {} \; | tee $(tty) | awk '{ SUM+=$1 } END { print SUM }'

with dc too: echo -n "0" "$(echo $(find <directory> -name '*.<extension>' -exec du -s {} \; | tee $(tty) | cut -f1 | tr '\n' '+') 0 + p)" | tr '\n' '+' | dc

Even though I already have a few projects with Vancouver Spray Foam Insulation Co, I would really like to learn more. Thanks for sharing helpful command lines.
