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