split files can be fixed using -F if
              you  have the last split of the archive (the .zip file).  If this
              file is missing, you must use -FF to fix the archive, which  will
              prompt you for the splits you have.

              Currently  the  fix options can’t recover entries that have a bad
              checksum or are otherwise damaged.

       -FI
       --fifo [Unix]  Normally zip skips reading any FIFOs  (named  pipes)  en‐
              countered,  as  zip  can hang if the FIFO is not being fed.  This
              option tells zip to read the contents of any FIFO it finds.

       -FS
       --filesync
              Synchronize the contents of an archive with the files on the  OS.
              Normally  when  an  archive  is  updated, new files are added and
              changed files are updated but files that no longer exist  on  the
              OS  are  not deleted from the archive.  This option enables a new
              mode that checks entries in the archive against the file  system.
              If  the  file time and file size of the entry matches that of the
              OS file, the entry is copied from the old archive instead of  be‐
              ing read from the file system and compressed.  If the OS file has
              changed, the entry is read and compressed as usual.  If the entry
              in  the  archive  does  not  match a file on the OS, the entry is
              deleted.  Enabling this option should create  archives  that  are
              the  same  as new archives, but since existing entries are copied
              instead of compressed, updating an existing archive with -FS  can
              be  much faster than creating a new archive.  Also consider using
              -u for updating an archive.

              For this option to work, the archive should be updated  from  the
              same directory it was created in so the relative paths match.  If
              few files are being copied from the old archive, it may be faster
              to create a new archive instead.

              Note  that the timezone environment variable TZ should be set ac‐
              cording to the local timezone in order for this  option  to  work
              correctly.   A  change in timezone since the original archive was
              created could result in no times matching  and  recompression  of
              all files.

              This  option deletes files from the archive.  If you need to pre‐
              serve the original archive, make a copy of the archive  first  or
              use the --out option to output the updated archive to a new file.
              Even  though  it may be slower, creating a new archive with a new
              archive name is safer, avoids mismatches between archive  and  OS
              paths, and is preferred.

       -g
       --grow
              Grow (append to) the specified zip archive, instead of creating a
              new  one.  If  this  operation fails, zip attempts to restore the
              archive to its original state.  If  the  restoration  fails,  the
              archive  might  become  corrupted.  This  option  is ignored when
              there’s no existing archive or when at least one  archive  member
              must be updated or deleted.

       -h
       -?
       --help
              Display the zip help information (this also appears if zip is run
              with no arguments).

       -h2
       --more‐help
              Display extended help including more on command line format, pat‐
              tern matching, and more obscure options.

       -i files
       --include files
              Include only the specified files, as in:

                     zip ‐r foo . ‐i \*.c

              which  will  include only the files that end in .c in the current
              directory and its subdirectories.  (Note  for  PKZIP  users:  the
              equivalent command
