Zip files and directories in Linux using this script:
zip -r name_of_zip_file.zip directoryname
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 (probably not what was intended).
