PKZIP Command Line Reference

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

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).

(UNIX) 

note:a "-" before a filetype sub-option tells PKZIP to exclude the specified filetype(s) regardless of the default configuration setting (e.g. -filetype=-hidden will exclude hidden files regardless of the default configuration setting)  

hidden - include/exclude filenames that have a dot "." in the first position of the filename (e.g. .profile) 

pipe - include/exclude pipe files. These are files having a file mode starting with "p" (e.g. prwxrw-rw-) 

slink - include/exclude symbolic links. These are files having a file mode starting with "l" (e.g. lrw-rw-rw-) 

hlink -include/exclude hard linked files. These are linked files that are not symbolic links. They are files with a link count >1 

none - exclude all of the above file types; Generally, this option should be followed by one, or more, file types. This results in just the type(s) specified being included in the ZIP file. For example, -filetype=none, pipe results in only PIPE files being included 

all - include all of the above file types 

regular - include/exclude regular files 

----------------------------- 

default = regular

Name/Description: Value(s): Example usage: Used with:
id 

preserve the user ID (UID) and/or group ID (GID) on extraction 

(UNIX) 

note: the user who extracts files with preserved UID and GID information must have the same UID as is archived in the .ZIP file or root (superuser) file privileges 

userid - retain the user ID on extraction 

groupid - retain the group ID on extraction 

all - retain both the user ID and group ID on extraction 

none - retain neither the user ID or group ID on extraction 

----------------------------- 

no default value

----------------------------- 

no default value

pkzip25 -add -include=*.doc save.zip 

in this example, only .doc files will be compressed 

pkzip25 -config -include=*.txt 

in this example, you are setting up .txt files as the files that you always want to compress or extract, until you change the default or override from the command line with the exclude option 

note: when you use the include option with the configuration command, PKZIP prompts you to configure the include default for add and/or extract operations

add, extract, delete, test, view
Name/Description: Value(s): Example usage: Used with:

note: following a link results in a larger .ZIP file since two copies of file data are compressed as though each link is a separate file

hlink - hard links will be followed (stored) rather than preserved 

slink - symbolic links will be followed (stored) rather that preserved 

all - symbolic and hard links will be followed rather than preserved 

none - symbolic and hard links will be preserved 

----------------------------- 

default = none

pkzip25 -add -filetype=hlink   -links=hlink save.zip 

this example compresses regular and hard linked files as well as duplicates link and file data for each hard linked file added to the .ZIP file

note: the crc and ratio sub-options will not work with the add command and sort option 

crc - sort by CRC value 

date - sort by file date of file 

extension - sort by file extension 

name - sort alphabetically by name 

natural - sort in the order that the file was compressed 

ratio - sort by compression ratio 

size - sort by the original, uncompressed size of the file ("length" in display) 

none - do not sort (same as natural) 

----------------------------- 

default = natural 

default if used on command line without a sub-option = name

pkzip25 -add -sort=date save.zip *.doc 

pkzip25 -config -sort=date 

note: when you use the sort option with the configuration command, PKZIP prompts you to configure the mask default for add, extract, and/or view operations

add, extract, test, view
Name/Description: Value(s): Example usage: Used with:
span 

forces disk spanning in the event that PKZIP is unable to detect the fact that destination directory is on removable media 

note: the spanning process should proceed automatically; a command line option is usually not necessary to enable this feature 

(DOS, OS/2)

no suboptions 

----------------------------- 

no default value

pkzip25 -add -span a:\save.zip *.doc add
Name/Description: Value(s): Example usage: Used with:
speed 

sets the level of compression to 1, which is the least but fastest compression 

configurable

no suboptions 

----------------------------- 

no default value

pkzip25 -add -speed save.zip *.doc 

pkzip25 -config -speed

add
Name/Description: Value(s): Example usage: Used with:
store 

sets the level of compression to 0 (no compression), and only stores the files within the .ZIP file 

configurable

no suboptions 

----------------------------- 

no default value

pkzip25 -add -store save.zip *.doc 

pkzip25 -config -store 

add
Name/Description: Value(s): Example usage: Used with:
temp 

creates the temporary .ZIP file required by PKZIP, on specified drive  

note: the temp option only works when updating an existing .ZIP file

the drive and/or path. 

e.g. C: or /root/temp 

----------------------------- 

no default value

pkzip25 -add -temp=Z:\PUBLIC test.zip *.txt 

this example updates the .ZIP file test.zip and uses the Z:\PUBLIC directory location for the temp file 

pkzip25 -add -temp=/temp test.zip *.txt 

this example updates the .ZIP file test.zip and uses the /temp directory location for the temp file 
 

add
Name/Description: Value(s): Example usage: Used with:
test 

test the integrity of files within a .ZIP file 

configurable

all - all files in .ZIP file will be tested 

freshen - only those files in the .ZIP file which already exist in the extract directory and that have a file modification date newer that the files already in the directory will be tested 

update - files in the .ZIP file which already exist in the target directory and that are "newer" than those files and files that are "not" in the target directory will be tested 

----------------------------- 

default = all

pkzip25 -test save.zip stand-alone
Name/Description: Value(s): Example usage: Used with:
times 

specify whether file access, creation, and modification times are to be preserved 

(DOS, UNIX) 
 

access - restores the time of last access to file(s) on extraction 

modify - restores the time of last modification to file(s) on extraction 

create - restores the time of creation to file(s) on extraction (DOS) 

all - all file times are restored 

none - file times are not restored 

------------------------------- 

default = none 

pkzip25 -extract -times=access save.zip  extract
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
