How To Use PKZIP on Linux Command Line |
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).

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

(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
pkzip25 -extract -id=userid save.zip extract
Name/Description: Value(s): Example usage: Used with:

-----------------------------
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:

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

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)

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
-----------------------------
