How do I rename a file in a 7zip archive using the CLI?

The p7zip Unix tool is based on 7zip and should support the same command line options described in its help file.

To rename from the CLI you need version 9.30 or higher, and to rename multiple files in one go, you need at least version 15.05 (which cannot be ported yet):

Syntax for renaming files inside archives

7za rn <archive_name> <src_file_1> <dest_file_1> [ <src_file_2> <dest_file_2> ... ]

      

        
        
        
      

    

It also allows you to move files around eg. to subdirectory:

7za rn archive.7z old.txt new/location/new.txt
