Zip including hidden files

Or you can add more simple

zip 1.zip ./

EDIT: The correct way is zip -r 1.zip .

The commands shown in my previous answer below are incorrect because they also include the parent directory.

Have you tried this:

zip yourfile.zip sourcedir/* .*

or you in your case

zip 1.zip * .[^.]*'

It should include all hidden files also.
