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.
