More efficient way to find & tar millions of files

Question

I\'ve got a job running on my server at the command line prompt for a two days now:

find data/ -name filepattern-*2009* -exec tar uf 2009.tar {} ;

Answer 1

To correctly handle file names with weird (but legal) characters (such as newlines, ...) you should write your file list to filesOfInterest.txt using find's -print0:

find -x data -name "filepattern-*2009*" -print0 > filesOfInterest.txt
tar --null --no-recursion -uf 2009.tar --files-from filesOfInterest.txt
