How to create multipart 7zip file in Linux?

Question

How can I create a multipart 7zip file in Linux using the p7zip console client?

Many people referred me to it. My console app is

7-Zip [64] 9.13 beta  Copyright (c) 1999-2010 Igor Pavlov  2010-04-15
p7zip Version 9.13 (locale=C,Utf16=off,HugeFiles=on,4 CPUs)

IMO the best solution is to avoid 7-zip and use xz. To split archives, read here: stackoverflow.com/questions/1120095/… — Marco Sulla, Commented Sep 27, 2014 at 11:05
Thank you. I'm not even for sure the xz option was even standard on most distros when I originally asked this question. — hopeseekr, Commented Dec 7, 2014 at 0:09

Use the -v option (v is for volume) -v100m will split the archive into chunks of 100MB.

7z -v option supports b k m g (bytes, kilobytes, megabytes, gigabytes)

Example: 7z -v100m a my_zip.7z my_folder/

Be aware that 7zip doesn't preserve file ownership information on Linux.

7z seem not to append files if file are already in the archive or if archive already exists.

Also works on OSX using brew install p7zip.

Full command example: 7z -v100m a my_zip.7z my_folder/

The example command creates 100m volumes named my_zip.7z.001, my_zip.7z.002, etc. To extract from these volumes, use this command: 7z e my_zip.7z.001. Even though you are specifying only the the first part in the command, the command will look for all the parts in the same folder and extract it.
