Another way to calculate sum size of all files matching a pattern

find . -iname '*.jar' | xargs du -ks | cut -f1 | xargs echo | sed "s/ /+/g" | bc
Here the pattern is '*.jar', you could pass in any pattern. Another, maybe nicer way to do this is http://www.commandlinefu.com/commands/view/1921/summarise-the-size-of-all-files-matching-a-simple-regex You could replace sed with tr
Sample Output

What Others Think

Why not use the -c flag of du? It displays the total sum. find . -iname '*.jar' | xargs du -kc | tail -1 Also, if there are possibly spaces or other nasty characters in file names, make sure to use -print0 with the find command (and the -0 flag to xargs, of course).

inof, yours doesn't work because there are multiple "totals" lines. find . -iname '*.c' | xargs du -kc | grep total 19392 total 8344 total 24940 total 9976 total 23876 total 39716 total 44700 total 25280 total 27456 total 30868 total 26688 total 26744 total

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
