Move the specified files into the  zip  archive;  actually,  this
              deletes  the  target directories/files after making the specified
              zip archive. If a directory becomes empty after  removal  of  the
              files, the directory is also removed. No deletions are done until
              zip  has  created  the archive without error.  This is useful for
              conserving disk space, but is potentially dangerous so it is rec‐
              ommended to use it in combination with -T to test the archive be‐
              fore removing all input files.

       -MM
       --must‐match
              All input patterns must match at least one  file  and  all  input
              files  found  must  be  readable.  Normally when an input pattern
              does not match a file the "name not matched"  warning  is  issued
              and when an input file has been found but later is missing or not
              readable  a missing or not readable warning is issued.  In either
              case zip continues creating the archive, with missing or  unread‐
              able new files being skipped and files already in the archive re‐
              maining  unchanged.   After  the archive is created, if any files
              were not readable zip returns the OPEN error  code  (18  on  most
              systems)  instead  of  the  normal success return (0 on most sys‐
              tems).  With -MM set, zip exits as soon as an  input  pattern  is
              not matched (whenever the "name not matched" warning would be is‐
              sued)  or when an input file is not readable.  In either case zip
              exits with an OPEN error and no archive is created.

              This option is useful when a known list of files is to be  zipped
              so  any  missing or unreadable files will result in an error.  It
              is less useful when used with wildcards, but zip will still  exit
              with  an  error  if  any input pattern doesn’t match at least one
              file and if any matched files are unreadable.   If  you  want  to
              create  the  archive  anyway  and only need to know if files were
              skipped, don’t use -MM and just check the return code.  Also  -lf
              could be useful.

       -n suffixes
       --suffixes suffixes
              Do  not  attempt to compress files named with the given suffixes.
              Such files are simply stored (0% compression) in the  output  zip
              file, so that zip doesn’t waste its time trying to compress them.
              The  suffixes  are separated by either colons or semicolons.  For
              example:

                     zip ‐rn .Z:.zip:.tiff:.gif:.snd  foo foo

              will copy everything from foo into foo.zip, but  will  store  any
              files  that  end in .Z, .zip, .tiff, .gif, or .snd without trying
              to compress them (image and sound files often have their own spe‐
              cialized compression methods).  By default, zip does not compress
              files with extensions in  the  list  .Z:.zip:.zoo:.arc:.lzh:.arj.
              Such  files are stored directly in the output archive.  The envi‐
              ronment variable ZIPOPT can be used to  change  the  default  op‐
              tions. For example under Unix with csh:

                     setenv ZIPOPT "‐n .gif:.zip"

              To attempt compression on all files, use:

                     zip ‐n : foo

              The  maximum  compression  option -9 also attempts compression on
              all files regardless of extension.

              On Acorn RISC OS systems the suffixes are actually  filetypes  (3
              hex  digit  format). By default, zip does not compress files with
              filetypes in the list DDC:D96:68E (i.e. Archives, CFS  files  and
              PackDir files).
