I know the following situation is not likely, but the above will
break if you have newlines in your filenames.


$ mkdir /tmp/tartest
$ cd /tmp/tartest
$ touch "`echo -en 'test\nblah.prj'`"
$ find . -name "*.prj" | tar -T- -zcf test.tar.gz
tar: ./test: Cannot stat: No such file or directory
tar: blah.prj: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors

But this will fix it:

$ find . -name "*.prj" -print0 | tar --null -T- -zcf test.tar.gz
$ tar tzf test.tar.gz
