best way to extract a file from a zip file and put it back into the zip file after editing

Question

I am wondering if anyone can help me with a shell script to do the following job:

Extract a file from a zip file and put it back in after some editing, e.g. using sed to do some replacement.

I want to avoid extracting all contents of the zip file into a temporary folder. It could be possible that the zip file contains files with the same name as the one I want to replace with editing. In such case, I want to specify the full path of such file inside the zip file.

Is there any good way to do this task?

Answer 1

1. Extract a file from a zip file:

   unzip file.zip file/you/want/to/extract/the_file.txt

2. Modify the_file.txt

3. Put it back:

   zip file.zip file/you/want/to/extract/the_file.txt

That should get you started.
