Top Forums Shell Programming and Scripting Unzip files without overwriting Post 302400928 by drewk on Thursday 4th of March 2010 01:28:47 PM

How about unzipping a.zip and b.zip into new, temporary directories then looping through each file in each temp directory to combine into the destination. Then delete the temporary directories.


Alternatively, use zcat or unzip -p to access the compress stream of the file inside the zip file and decompress if different. No more efficient and more complex to do it this way I think.
