Decryption Xmay not be supported at some sites. See DESCRIPTION for more details. X.PD X.SH DESCRIPTION X.I FUnZip Xacts as a filter; that is, it assumes that a ZIP archive is being piped into Xstandard input, and it extracts the first member from the archive to stdout. XGiven the limitation on single-member extraction, \fIFUnZip\fP is most Xuseful in conjunction with a secondary archiver program such as tar(1). XThe following section includes an example illustrating this usage in the Xcase of disk backups to tape. X.PD X.SH EXAMPLES XTo use \fIFUnZip\fP to extract the first member file of the archive test.zip Xand to pipe it into more(1): X.PP X.IP "\t\fIfunzip\fP < test.zip `7C more" X.PP XTo use \fIFUnZip\fP to test the first member file of test.zip (any errors Xwill be reported on standard error): X.PP X.IP "\t\fIfunzip\fP < test.zip > /dev/null" X.PP XTo use \fIZip\fP and \fIFUnZip\fP in place of compress(1) and zcat(1) for Xtape backups: X.PP X.IP "\ttar cf \- . `7C \fIzip\fP \-7 `7C dd of=/dev/nrst0 obs=8k" X.IP "\tdd if=/dev/nrst0 ibs=8k `7C \fIfunzip\fP `7C tar xf \-" X.PP X(where, for example, nrst0 is a SCSI tape drive). X.PD X.SH LIMITATIONS XThere is presently no way to extract any member but the first from a ZIP Xarchive. This would be useful in the case where a ZIP archive is included Xwithin another archive. X.PP XAn alternate mechanism for passing the password to \fIFUnZip\fP would Xbe preferable to putting it on the command line. X.PP X\fIFUnZip\fP would be useful under OS/2, too. X.PP XThe functionality of \fIFUnZip\fP should be included in \fIUnZip\fP Xdirectly (future release).
