How to tar certain file types in all subdirectories?

linux tar

find ./someDir -name "*.php" -o -name "*.html" | tar -cf my_archive -T -

linux tar

If you're using bash version > 4.0, you can exploit shopt -s globstar to make short work of this:

shopt -s globstar; tar -czvf deploy.tar.gz **/Alice*.yml **/Bob*.json

this will add all .yml files that starts with Alice from any sub-directory and add all .json files that starts with Bob from any sub-directory.

linux tar

One method is:

tar -cf my_archive.tar $( find -name "*.php" -or -name "*.html" )

There are some caveats with this method however:

It will fail if there are any files or directories with spaces in them, and
it will fail if there are so many files that the maximum command line length is full.

A workaround to these could be to output the contents of the find command into a file, and then use the "-T, --files-from FILE" option to tar.
