with 8‐bit passwords (for example, passwords with ac‐
       cented  European  characters)  may not be portable across systems and/or
       other archivers.  This problem stems from the use of  multiple  encoding
       methods for such characters, including Latin‐1 (ISO 8859‐1) and OEM code
       page  850.   DOS  PKZIP 2.04g uses the OEM code page; Windows PKZIP 2.50
       uses Latin‐1 (and is therefore incompatible with  DOS  PKZIP);  Info‐ZIP
       uses  the  OEM  code  page  on DOS, OS/2 and Win3.x ports but ISO coding
       (Latin‐1 etc.) everywhere else; and Nico Mak’s WinZip 6.x does not allow
       8‐bit passwords at all.  UnZip 5.3 (or newer) attempts to  use  the  de‐
       fault character set first (e.g., Latin‐1), followed by the alternate one
       (e.g.,  OEM code page) to test passwords.  On EBCDIC systems, if both of
       these fail, EBCDIC encoding will be tested as a last resort.  (EBCDIC is
       not tested on non‐EBCDIC systems, because there are no  known  archivers
       that encrypt using EBCDIC encoding.)  ISO character encodings other than
       Latin‐1  are  not  supported.   The  new addition of (partially) Unicode
       (resp.  UTF‐8) support in UnZip 6.0 has not yet been adapted to the  en‐
       cryption  password  handling in unzip.  On systems that use UTF‐8 as na‐
       tive character encoding, unzip simply tries decryption with  the  native
       UTF‐8  encoded  password; the built‐in attempts to check the password in
       translated encoding have not yet been adapted for UTF‐8 support and will
       consequently fail.

EXAMPLES
       To use unzip to extract all members of the archive letters.zip into  the
       current  directory and subdirectories below it, creating any subdirecto‐
       ries as necessary:

       unzip letters

       To extract all members of letters.zip into the current directory only:

       unzip ‐j letters

       To test letters.zip, printing only a summary message indicating  whether
       the archive is OK or not:

       unzip ‐tq letters

       To  test  all  zipfiles in the current directory, printing only the sum‐
       maries:

       unzip ‐tq \*.zip

       (The backslash before the asterisk is only required if the shell expands
       wildcards, as in Unix; double quotes could have been used instead, as in
       the source examples below.)  To extract to standard output  all  members
       of  letters.zip  whose  names  end in .tex, auto‐converting to the local
       end‐of‐line convention and piping the output into more(1):

       unzip -ca letters \*.tex | more

       To extract the binary file paper1.dvi to standard output and pipe it  to
       a printing program:

       unzip -p articles paper1.dvi | dvips

       To  extract  all  FORTRAN  and  C source files‐‐*.f, *.c, *.h, and Make‐
       file‐‐into the /tmp directory:

       unzip source.zip "*.[fch]" Makefile ‐d /tmp

       (the double quotes are necessary only in Unix and only  if  globbing  is
       turned  on).   To  extract all FORTRAN and C source files, regardless of
       case (e.g., both *.c and *.C, and any makefile,  Makefile,  MAKEFILE  or
       similar):

       unzip -C source.zip "*.[fch]" makefile ‐d /tmp

       To  extract any such files but convert any uppercase MS‐DOS or VMS names
       to lowercase and convert the line‐endings of all of the files to the lo‐
       cal standard (without respect to any files that might  be  marked  ‘‘bi‐
       nary’’):

       unzip -aaCL source.zip "*.[fch]" makefile ‐d /tmp

       To  extract  only newer versions of the files already in the current di‐
       rectory, without querying (NOTE:  be careful of unzipping in  one  time‐
       zone a zipfile created in another‐‐ZIP archives other than those created
       by  Zip  2.1  or  later contain no timezone information, and a ‘‘newer’’
       file from an eastern timezone may, in fact, be older):

       unzip -fo sources

       To extract newer versions
