How to include file in gsutil rsync?

Question

gsutil rsync has an "exclude" option (-x), but no "include" option. Is there some way to include a selected file without rsyncing the entire directory? Excluding all but the desired file will not work because random files will be saved to that directory.

Answer 1

If you know the name of a single file you want to sync you don't even need to perform an ls like Balajee suggests. Just specify that base file name in the reverse regex:

gsutil rsync -x '(?!^myfile\.txt$)' ./directory-with-desired-file gs://my-bucket
