I have the following folder structure
folder | |--foo.txt | |--sub_folder | |--bar.txt
I want to zip the content (files and sub folders) of folder without including the root folder in the zip.
I have tried command
zip -r package.zip folder
But this includes the root folder. Also tried the following form
zip -j -r package.zip folder
But this will flatten all the directory structures and just include the files. How do I preserve the internal directory structure but ignore the parent folder?
