This document was created to introduce you to the command line version of PKZIP. One of the significant differences between this version of PKZIP and previous versions of PKZIP/PKUNZIP is the consolidation of compression and extraction (zip/unzip) functionality into a single program. In other words, the same program compresses and extracts files. Additionally, the command line syntax has been changed. This was done to make PKZIP easier to understand and use for the novice and power user alike. Hopefully, you will find all of the functionality of previous versions of PKZIP with a simpler more intuitive user interface.

If you have used earlier command line versions of PKZIP (e.g. PKZIP 2.04g), you may find the PKZIP Command Line Translation Table helpful.

Please keep in mind that although this document does include basic information to help you get started using PKZIP, it is not a user's manual. The Registered and Licensed versions of PKZIP come with extensive documentation including a comprehensive user's manual. The PKZIP User's Manual includes such things as tutorials as well as in depth discussions of PKZIP's advanced features.

PKZIP Usage:

Usage: pkzip25 [command] [options] zipfile [@list] [files...]

Examples:

     View .ZIP file contents: pkzip25 zipfile

     Create a .ZIP file: pkzip25 -add zipfile file(s)...

     Extract files from .ZIP: pkzip25 -extract zipfile

These are only basic examples of PKZIP's capability

PKZIP Command Reference:

An alphabetical listing of available PKZIP commands and options follows. You may wish to scroll through the entire list or click on one of the hyperlinks below to go directly to the specified command/option section.

PKZIP Commands:

PKZIP Options:

This document contains reference information on every PKZIP command and option. For each command/option, the following information is provided:
 

Category:	Represents:
Name/Description	The full name of the command/option and a brief description of what that command/option does.  If the command/option can be configured (defaulted) in the Configuration file, the word "configurable" appears after the description.
Value(s)	The value(s) associated with this command/option, including the "default" value for each.  If a command/option does not have an associated value, the phrase "no suboptions" appears.
Example usage	An example of how to include this command/option in your PKZIP command line, including possible abbreviations. For most options, you can abbreviate the command/option. These abbreviations are illustrated in the examples used in this appendix.
Used with	This command can be used for compression, extraction, viewing, testing, a combination, or as a stand-alone (none of the above).

Note: Most commands and options documented here work in all versions of PKZIP. In instances where a command, option, or suboption is specific to a platform or operating system, the document will indicate as much. (e.g. UNIX, DOS, OS/2).

Name/Description:	Value(s):	Example usage:	Used with:
translate  analyze text files in a .ZIP file and if necessary translate the carriage return/newline sequence for compatibility with a specified operating system  (UNIX)	none - no translation is performed on text files  dos - translates text files so lines end with a return/newline pair as per the DOS standard  mac - translates text files so lines end with a single carriage return as per the MacOS standard  unix - translates text files so lines end with a single newline as per the UNIX (i.e. POSIX) standard  -------------------------------   default = none  default if used on command line without a sub-option = native operating system compatibility translation	pkzip25 -extract -translate=unix save.zip	extract
Name/Description:	Value(s):	Example usage:	Used with:
version  determine the version of PKZIP you are running  note: PKZIP also returns the version number to the shell by way of setting the error level; the version number value is passed directly to the shell and as such is not viewable by the user	major - returns the major version number of the release  minor - returns the minor number of the release (e.g. - if the version number is 2.5.1, the value returned is 5)  step - returns the step, or patch value. (e.g. - if the version is 2.04.01, the step value returned is 1)  -----------------------------  default = major	pkzip25 -version	stand-alone
Name/Description:	Value(s):	Example usage:	Used with:
view  display information about the files within a .ZIP file, for example, the compressed size of a file  configurable	brief - present information in the most compact manner  details - present information in the most detailed manner  normal - present information in the normal manner  -----------------------------  default = normal	pkzip25 -view save.zip	stand-alone
Name/Description:	Value(s):	Example usage:	Used with:
volume  store/restore the volume label with the .ZIP file  configurable  (DOS, OS/2)	a drive letter (for example, C)  -----------------------------  default = no volume label  default if used on command line without a sub-option = current drive	pkzip25 -add -volume=C save.zip *.docs	add, extract
Name/Description:	Value(s):	Example usage:	Used with:
warning  pause after every warning, and prompt you to continue or not  configurable	no suboptions  -----------------------------  no default value	pkzip25 -ext -warn save.zip *	add, extract, test, view
Name/Description:	Value(s):	Example usage:	Used with:
zipdate  set the file modification date of the .ZIP file   configurable	newest - set to the date of the "newest" file within the .ZIP file  oldest - set to the date of the "oldest" file within the .ZIP file  retain - retain the original date of the .ZIP file (the date on which the .ZIP file was created)  none - disable the .ZIP file date in the config file, and set the .ZIP date as the last modification date  -----------------------------  default = the current date  default if used on command line without a sub-option = retain	pkzip25 -add=update   -zipdate=retain save.zip *.txt	add
