Debian                                          January 23, 2023                                      ZIPTOOL(1)

ziptool modifies the zip archive zip-archive according to the commands given.

       Supported options:

       -c           Check zip archive consistency when opening it.

       -e           Error if archive already exists (only useful with -n).

       -g           Guess file name encoding (for stat command).

       -h           Display help.

       -llength    Only read length bytes of archive.  See also -o.

       -n           Create archive if it doesn't exist.  See also -e.

       -ooffset    Start reading input archive from offset.  See also -l.

       -r           Print raw file name encoding without translation (for stat command).

       -s           Follow file name convention strictly (for stat command).

       -t           Disregard current file contents, if any.  Note: use this with care, it deletes all  existing
                    file contents when you modify the archive.
