How do I tar a directory of files and folders without including the directory itself?

Question

I typically do:

tar -czvf my_directory.tar.gz my_directory

What if I just want to include everything (including any hidden system files) in my_

Answer 1

# tar all files within and deeper in a given directory
# with no prefixes ( neither / nor ./ )
# parameters:  
function tar_all_in_dir {
    { cd "$1" && find -type f -print0; } \
    | cut --zero-terminated --characters=3- \
    | tar --create --file="$2" --directory="$1" --null --files-from=-
}

Safely handles filenames with spaces or other unusual characters. You can optionally add a -name '*.sql' or similar filter to the find command to limit the files included.
