Install the p7zip package like this:

Run the command like this. It will give you the usage which shows the available options.
Add files to an archive. This will create it if it doesn’t exist.
7z a mycompressedfile.7z test1.txt
Add another file to an existing archive.
7z a mycompressedfile.7z test2.txt
Using the ‘a’ option to add a file that is alread in the archive will re-add the file even if there aren’t any changes.
Using the ‘u’ option will update the file in the archive only if it has changed. Otherwise it will do nothing.
7z u mycompressedfile.7z test2.txt
List all the files in an existing archive:
7z l mycompressedfile.7z
NOTE - Pay attention to where you extract things. You don’t want the entire contents of an archive being dumped into an existing directory that already has files in it. This can get messy.
Extract an archive:
7z e mycompressedfile.7z
Extract with full path:
7z x mycompressedfile.7z
Extract to a directory named “NEW”:
7z x -oNEW mycompressedfile.7z
