-r Travel the directory structure recursively; for example:

zip -r foo.zip foo

or a bit more concisely

zip -r foo foo

In this case, all the files and directories in foo are saved in
a zip archive named foo.zip, including files with names starting
with ".", since the recursion does not use the shell's file-name
substitution mechanism. If you wish to include only a specific
subset of the files in directory foo and its subdirectories, use
the -i option to specify the pattern of files to be included.
You should not use -r with the name ".*", since that matches
".." which will attempt to zip up the parent directory (proba-
bly not what was intended).
