Ubuntu Manpage: ziptool - modify zip archives

NAME

       ziptool - modify zip archives

SYNOPSIS

       ziptool [-cegHhmnrst] zip-archive command [command-args ...]  [command [command-
               args ...] ...]

DESCRIPTION

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 Write files with holes compactly. In other words, when the modified zip archive
contains long runs of zeroes, write a basic run-length encoded block instead. Note:
This command is for internal testing of libzip(3) and will usually create invalid zip
archives.

-h Display help.

-m Read archive into memory, and modify there; write out at end. Note: This command is
for internal testing of libzip(3).

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

-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.
