FUNZIP(1)                                               FUNZIP(1)


NAME
       funzip - extract from a ZIP archive file as a filter

SYNOPSIS
       [...]  |  funzip [ password ]  |  [...]

ARGUMENTS
       [password]  Optional password to be used if ZIP archive is
                   encrypted.  Decryption may not be supported at
                   some sites.  See DESCRIPTION for more details.

DESCRIPTION
       FUnZip acts as a filter; that is, it assumes  that  a  ZIP
       archive  is  being  piped  into  standard  input,  and  it
       extracts the first member  from  the  archive  to  stdout.
       Given  the  limitation on single-member extraction, FUnZip
       is most useful in conjunction with  a  secondary  archiver
       program such as tar(1).  The following section includes an
       example illustrating this usage in the case of disk  back-
       ups to tape.

EXAMPLES
       To  use  FUnZip  to  extract  the first member file of the
       archive test.zip and to pipe it into more(1):


            funzip < test.zip | more

       To use FUnZip to test the first member  file  of  test.zip
       (any errors will be reported on standard error):


            funzip < test.zip > /dev/null

       To  use Zip and FUnZip in place of compress(1) and zcat(1)
       for tape backups:


            tar cf - . | zip -7 | dd of=/dev/nrst0 obs=8k

            dd if=/dev/nrst0 ibs=8k | funzip | tar xf -

       (where, for example, nrst0 is a SCSI tape drive).

LIMITATIONS
       There is presently no way to extract any  member  but  the
       first  from  a  ZIP  archive.  This would be useful in the
       case where  a  ZIP  archive  is  included  within  another
       archive.

       An  alternate mechanism for passing the password to FUnZip
       would be preferable to putting it on the command line.

       FUnZip would be useful under OS/2, too.

FUNZIP(1)                                               FUNZIP(1)


       The functionality of FUnZip should be  included  in  UnZip
       directly (future release).
