When we face the problem of calculating size of some files then we often think of **du**.. But how could we count size of files found by **find**? We could do this with this simple one-liner:

1 |
find /somewhere -name 'some_files*' -exec wc -c '{}' + |

Find command is simple here. We use here also a POSIX solution – ending “exec” with a plus-sign not a semicolon. This form groups the finding results into sets and then run commands on whole that set. And that’s why we use it here – our **wc -c** command is run on a whole set of results giving us in the end line the total size of all the files:

1 2 3 4 5 6 7 |
[root@docent log]# find . -name 'maillog*' -exec wc -c '{}' +<br /> 6847 ./maillog-20111120<br /> 6137 ./maillog<br /> 6580 ./maillog-20111204<br /> 5028 ./maillog-20111113<br /> 6424 ./maillog-20111127<br /> 31016 total |

We could shorten that a little:

1 2 |
[root@docent log]# find . -name 'maillog*' -exec wc -c '{}' + | tail -1<br /> 31016 total |

And If we would like to have only the number:

1 2 |
[root@docent log]# find . -name 'maillog*' -exec wc -c '{}' + | tail -1 | cut -d' ' -f 1<br /> 31016 |
