It is not concerned with displaying any details of the compressed data stored in the zip file. .PP The program assumes prior understanding of the internal structure of a Zip file. You should have a copy of the Zip \s-1APPNOTE\s0 file at hand to help understand the output from this program (\*(L"\s-1SEE\s0 \s-1ALSO\s0\*(R" for details). .SS "\s-1OPTIONS\s0" .IX Subsection "OPTIONS" .IP "\-v" 5 .IX Item "-v" Enable Verbose mode .IP "\-h" 5 .IX Item "-h" Display help .PP By default zipdetails will output the details of the zip file in three columns. .IP "Column 1" 5 .IX Item "Column 1" This contains the offset from the start of the file in hex. .IP "Column 2" 5 .IX Item "Column 2" This contains a textual description of the field. .IP "Column 3" 5 .IX Item "Column 3" If the field contains a numeric value it will be displayed in hex. Zip stored most numbers in little-endian format \- the value displayed will have the little-endian encoding removed. .Sp Next, is an optional description of what the value means. .PP If the \f(CW\*(C`\-v\*(C'\fR option is present, column 1 is expanded to include .IP "\(bu" 5 The offset from the start of the file in hex. .IP "\(bu" 5 The length of the filed in hex. .IP "\(bu" 5 A hex dump of the bytes in field in the order they are stored in the zip file. .SH "TODO" .IX Header "TODO" Error handling is still a work in progress. If the program encounters a problem reading a zip file it is likely to terminate with an unhelpful error message. .SH "SEE ALSO" .IX Header "SEE ALSO" The primary reference for Zip files is the \*(L"appnote\*(R" document available at <http://www.pkware.com/documents/casestudies/APPNOTE.TXT>. .PP An alternative is the Info-Zip appnote. This is available from ftp://ftp.info\-zip.org/pub/infozip/doc/ <ftp://ftp.info-zip.org/pub/infozip/doc/> .PP The \f(CW\*(C`zipinfo\*(C'\fR program that comes with the info-zip distribution (http://www.info\-zip.org/ <http://www.info-zip.org/>) can also display details of the structure of a zip file. .PP See also IO::Compress::Zip, IO::Uncompress::Unzip. .SH "AUTHOR" .IX Header "AUTHOR" Paul Marquess \fIpmqs@cpan.org\fR. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright (c) 2011\-2012 Paul Marquess.
