be
              stored in the archive, and possibly a summary when finished  with
              each archive.  The -q[q] options suppress the printing of some or
              all of these messages.

       -s     [OS/2,  NT,  MS‐DOS]  convert spaces in filenames to underscores.
              Since all PC operating systems allow spaces in  filenames,  unzip
              by   default   extracts   filenames  with  spaces  intact  (e.g.,
              ‘‘EA DATA. SF’’).  This can be awkward, however, since MS‐DOS  in
              particular does not gracefully support spaces in filenames.  Con‐
              version of spaces to underscores can eliminate the awkwardness in
              some cases.

       -S     [VMS]  convert text files (-a, -aa) into Stream_LF record format,
              instead of the text‐file default, variable‐length record  format.
              (Stream_LF  is  the default record format of VMS unzip. It is ap‐
              plied unless conversion (-a, -aa and/or -b, -bb) is requested  or
              a VMS‐specific entry is processed.)

       -U     [UNICODE_SUPPORT  only]  modify  or disable UTF‐8 handling.  When
              UNICODE_SUPPORT is available, the option -U forces unzip  to  es‐
              cape  all  non‐ASCII  characters  from  UTF‐8  coded filenames as
              ‘‘#Uxxxx’’ (for UCS‐2 characters,  or  ‘‘#Lxxxxxx’’  for  unicode
              codepoints needing 3 octets).  This option is mainly provided for
              debugging  purpose when the fairly new UTF‐8 support is suspected
              to mangle up extracted filenames.

              The option -UU allows to  entirely  disable  the  recognition  of
              UTF‐8 encoded filenames.  The handling of filename codings within
              unzip falls back to the behaviour of previous versions.

              [old,  obsolete usage] leave filenames uppercase if created under
              MS‐DOS, VMS, etc.  See -L above.

       -V     retain (VMS) file version numbers.  VMS files can be stored  with
              a  version  number,  in  the  format file.ext;##.  By default the
              ‘‘;##’’ version numbers are stripped, but this option allows them
              to be retained.  (On file systems that limit filenames to partic‐
              ularly short lengths, the version numbers  may  be  truncated  or
              stripped regardless of this option.)

       -W     [only when WILD_STOP_AT_DIR compile‐time option enabled] modifies
              the  pattern matching routine so that both ‘?’ (single‐char wild‐
              card) and ‘*’ (multi‐char wildcard) do not  match  the  directory
              separator character ‘/’.  (The two‐character sequence ‘‘**’’ acts
              as a multi‐char wildcard that includes the directory separator in
              its matched characters.)  Examples:

           "*.c" matches "foo.c" but not "mydir/foo.c"
           "**.c" matches both "foo.c" and "mydir/foo.c"
           "*/*.c" matches "bar/foo.c" but not "baz/bar/foo.c"
           "??*/*" matches "ab/foo" and "abc/foo"
                   but not "a/foo" or "a/b/foo"

              This  modified  behaviour  is  equivalent to the pattern matching
              style used by the shells of some of UnZip’s supported target  OSs
              (one example is Acorn RISC OS).  This option may not be available
              on  systems  where the Zip archive’s internal directory separator
              character ‘/’ is allowed as regular character in native operating
              system filenames.  (Currently, UnZip uses the same pattern match‐
              ing rules for both wildcard zipfile specifications and zip  entry
              selection  patterns  in  most ports.  For systems allowing ‘/’ as
              regular filename character, the ‐W option would not work  as  ex‐
              pected on a wildcard zipfile specification.)
