How do I create a ZIP archive that preserves only the structure of the target directory and below?

Question

I need to create a zip archive where the unzipped result preserves the directory structure from the specified directory down. I also need to do this without actually switching to the directory.

My question is similar to this. After having read a great deal on the issue, I don't feel that anything has completely answered my question.

For example, I have:

/tmp
    /sub_dir
        /pertinent_dir
            /sub_folder_1/
                stuff.pdf
                stuff.xls
            /sub_folder_2/
                stuff.pdf
                stuff.xls
            /sub_folder_3/
                stuff.pdf
                stuff.xls

I need to be able to perform zip -r /tmp/sub_dir/pertinent_dir.zip /tmp/sub_dir/pertinent_dir/* such that the result only contains pertinent_dir and below. Again, I need to do this regardless of my current directory context. I've tried -j, but that doesn't seem to work. Perhaps it's not possible. Is there something I'm missing?

Solution 1

sh -c "cd /tmp/sub_dir/pertinent_dir/../  \
&& zip -r pertinent_dir.zip pertinent_dir/*"

Solution 2

You could use jar instead of zip:

jar cfM /tmp/sub_dir/pertinent_dir.zip -C /tmp/sub_dir pertinent_dir

You should probably mention that jar is part of the Java installation, and creates compatible zipfiles which can be extracted with unzip and so on.
