Running find...exec tar czvf only archives one file...need all files

Question

When attempting to run

find . -iname "*.gz" -mtime +7 -exec tar czvf all_gizip_$(date +%Y-%m-%d).tar.gz {} \;

I get the list of files

./corosync.log-20140620.gz
./corosync.log-20140618.gz
./rgmanager.log-20140620.gz
./fenced.log-20140620.gz
./rgmanager.log-20140618.gz
./qdiskd.log-20140618.gz

But the archive only gets the last item

 tar -tvf all_gizip_$(date +%Y-%m-%d).tar.gz
-rw-r--r-- root/root       506 2014-06-18 03:21 ./qdiskd.log-20140618.gz

What am I doing wrong?

Answer 1

Your command is running tar once for each file, and each call to tar creates an output of the same name, thus overwriting the previous output. So you end up with only the last file. You need something like

find . -iname "*.gz" -mtime +7 | xargs tar czvf all_gizip_$(date +%Y-%m-%d).tar.gz

This should work fine as long as your list of files isn't huge. If it is, then you'll probably want to switch to using tar rvf and doing a separate gzip step at the end.
