#NAME

streamzip - create a zip file from stdin

#SYNOPSIS

producer | streamzip [opts] | consumer
producer | streamzip [opts] -zipfile=output.zip

#DESCRIPTION

This program will read data from stdin, compress it into a zip container and, by default, write a streamed zip file to stdout. No temporary files are created.

The zip container written to stdout is, by necessity, written in streaming format. Most programs that read Zip files can cope with a streamed zip file, but if interoperability is important, and your workflow allows you to write the zip file directly to disk you can create a non-streamed zip file using the zipfile option.

#OPTIONS

#-zip64

Create a Zip64-compliant zip container. Use this option if the input is greater than 4Gig.

Default is disabled.

#-zipfile=F

Write zip container to the filename F.

Use the Stream option to enable the creation of a streamed zip file.

#-member-name=M

This option is used to name the "file" in the zip container.

Default is '-'.

#-stream

Ignored when writing to stdout.

If the zipfile option is specified, including this option will trigger the creation of a streamed zip file.

Default: Always enabled when writing to stdout, otherwise disabled.

#-method=M

Compress using method "M".

Valid method names are

* store    Store without compression
* deflate  Use Deflate compression [Deflault]
* bzip2    Use Bzip2 compression
* lzma     Use LZMA compression 

Note that Lzma compress needs IO::Compress::Lzma to be installed.

Default is deflate.

#-version

#When to use a Streamed Zip File

A Zip file created with streaming mode enabled allows you to create a zip file in situations where you cannot seek backwards/forwards in the file.

A good examples is when you are serving dynamic content from a Web Server straight into a socket without needing to create a temporary zip file in the filesystsm.

Similarly if your workfow uses a Linux pipelined commands.
