Reference to UNIX Commands and Options
This appendix contains reference information on every PKZIP command and option. For each command/option, the following information is provided:
Column | Purpose |
Name/Description | Gives the name of the command/option and a brief description of what it does. If a default value can be configured for the command/option, the word "Configurable" appears. |
Value(s) | Lists any sub-options or values associated with the command/option and specifies any initial default values |
Example usage | Shows examples of the command/option used in a PKZIP command line |
Used with | Identifies the item as a command or an option: a listing of standalone in this column means that the item is a command. For options, the column lists commands that the option can be used with. If standalone is included with a list of commands, the item can be used as an option with any of the listed commands or can be used by itself as a command. |
Information on each command/option follows:
Name/Description | Value(s) | Example usage | Used with |
|---|---|---|---|

Configurable | newest - Sets date of the archive to the date of the newest file in the archive oldest - Sets date of the archive to the date of the oldest file in the archive retain - When updating, keeps the date the archive had before it was updated. When creating a new archive, behaves the same as none none - Sets the date of the archive to the date of its latest modification | pkzipc -add=update -archivedate=retain save.zip *.txt | add, delete, fix, header, comment, sfx |
archiveeach Creates a separate archive for each of multiple files specified in a single command line. Can be used with archivetype and encode to create .tar.gz archives. | <destination> - Directory in which to create the archives By default, archives are created in the current directory. | Creates a separate ZIP archive for each file in the current directory: pkzipc -add -archiveeach *.* Creates the archives in a specified destination: pkzipc -add -archiveeach=C:\newzips *.* Creates .tar.gz archives: pkzipc -add -archiveeach -archivetype=tar -encode=gz C:\data*.* | add |
archivetype Explicitly specifies the type of archive to be acted on by the command. PKZIP works with ZIP archives by default or infers the archive type from the archive name. Use the archivetype option if PKZIP would assume or infer the wrong type. If you wish to create an OpenPGP file, always use archivetype=pgp. | bzip2 - Specifies the Bzip2 archive type.* zip - Specifies the .ZIP archive type. (default) gzip - Specifies the GZIP archive type.* pgp – Specifies the OpenPGP archive type. tar - Specifies the TAR archive type. uue - Specifies the UUENCODED archive type.* xxe - Specifies an XXENCODED archive type.* * These archive types can contain only one file. To use with multiple files, create an archive of one of the other archive types and use the encode option to encode this archive as the single-file archive type that you want. | Creates a TAR archive named myfile.foo.tar pkzipc -add -archivetype=tar myfile.foo Extracts from a BZIP2 archive on STDIN pkzipc -extract -archivetype=bzip2 -noarchiveextension -silent=input - Creates an OpenPGP archive encrypted for Bob Smith called myfile.pgp pkzipc -add -archivetype=pgp -recipient="Bob Smith" myfile.pgp *.txt | add, extract, test, view |
ascii Set the internal attribute bit (ASCII/Binary) to ASCII. Configurable | The file(s) or file pattern whose internal attribute bit you wish to set to ASCII; if no files are specified, PKZIP prompts for each file. | pkzipc -add -ascii=".txt" save.zip pkzipc -add -ascii save.zip * | add |
authenticate Verifies that an archive is signed. | No sub-options. | Extracts the archive if it was signed pkzipc -extract -authenticate signed.zip | extract |

For example, the US date format is one of the following: mmddyy | For compression: pkzipc -add -before=09152003 save.zip *.doc For extraction: pkzipc -extract -bef=09152003 save.zip *.doc | add, extract, delete, test, view, print, console |
binary Treats the files to be added as binary files: sets the internal ASCII/Binary attribute bit of the files to binary. Configurable | The file(s) or file pattern whose internal attribute bit you wish to set to binary; if no files are specified, PKZIP will prompt for each file. | pkzipc -add -binary=".exe" save.zip pkzipc -add -binary save.zip | add |
bzip2 Compress files using the BZIP2 method. Files compressed with this method can be extracted with most varieties of PKZIP version 4.6 and later. Other .ZIP programs may not be able to extract files compressed with BZIP2. | No sub-options Default compression level: 5 | To compress files using the bzip2 algorithm and level 9 compression: pkzipc -add -bzip2 -level=9 save.zip doc1.txt To compress files using the default compression level (level 5): pkzipc -add -bzip2 save.zip *.doc | add |
cd Encrypt file names and other metadata in a ZIP archive's central directory. Requires that passphrase and or recipient options also be used. Uses strong encryption; does not work with traditional ZIP encryption. Encrypting file names produces an archive that requires PKZIP or SecureZIP version 8.0 or later to open it. Configurable | encrypt - Encrypt file names and the archive's central directory normal - Do not encrypt file names; produces a normal ZIP file. Use to override a configured default setting that would otherwise encrypt file names. Default = encrypt | pkzipc -add -recipient="John Q. Public" -cd test.zip pkzipc -add -recipient="John Q. Public" -cd=normal test.zip pkzipc -add -passphrase=mysecret -cryptalgorithm=aes,256 -cd test.zip | add |
certificate Configurable | <Name> - The common name of the subject of the certificate (that is, the cn field in a string representation of a certificate; this is the name as viewed in Outlook, Internet Explorer, or PKZIP for Windows); optionally, precede with: cn= If the certificate name contains a space, enclose the certificate name in quotation marks ("My Name"). <Email address> - The email address of the certificate (that is, the e field in a string representation of a certificate); optionally, precede with: e= The specified certificate must exist in the MY certificate store. If more than one certificate in the MY store has the specified name, the first certificate is used. #<file name> - Specifies a PKCS#12 file that contains the certificate you want to use. If the certificate's private key is not in the PKCS#12 file with the certificate, use the keyfile option to point to the separate file that contains the private key. If necessary, use the keypassphrase option to specify a passphrase to read the private key. The certificate option can be used with the hash and sign options. By default, the .ZIP file is signed using the SHA-1 method, and both the central directory and files are signed. | pkzipc -add -certificate="John Smith" save.zip *.doc pkzipc -add -certificate=cn="John Smith" save.zip *.doc pkzipc -add -certificate=e= john.public@xyz.com save.zip *.doc pkzipc -add -certificate=#mycert.p12 save.zip *.doc | add, delete, comment, sign, header |
comment Include a text comment for files within an archive file. When you run the command, PKZIP prompts you to enter the comment. Configurable | all - All files already in the archive and all files added to or updated in the archive are commented unchanged - Only files that are not changed in the archive are commented add - Only newly added files and versions of files are commented freshen - Only newly added versions of files already in the archive are commented update - Only newly added files and versions of files already in the archive are commented (the opposite of unchanged) none - No comments added --------------------- Default = none Value if used on command line without a sub-option = add | pkzipc -add -comment=all save.zip *.doc | add, standalone |
configuration Defines default values for PKZIP commands and options | <command or option> - Any configurable command or option GUI - Invokes the configuration dialogs from the graphical PKZIP product. If specified, no other command line arguments are processed for configuration except more and silent, which can be set to govern the screen display of configuration settings. silent - Suppresses list of configured settings that is ordinarily displayed after a command or option is configured. --------------------- No default value. | pkzipc -config -extract=freshen To see the current configuration values, type: pkzipc -config To open the Configuration dialogs of the GUI product for use in setting configuration defaults: pkzipc -config=gui Configures overwrite option and suppresses display of settings afterward: pkzipc -config=silent -overwrite=never Configures silent option and suppresses display of settings afterward: pkzipc -config=silent -silent | standalone |
console Extracts files to the screen (standard output) instead of to disk | No sub-options. | pkzipc -console save.zip *.txt | standalone |
crl Warns if a certificate to be used for digital signing, encryption, or authentication is listed as revoked in an accessible CRL (certificate revocation list). Use with strict option to prevent the certificate from being used. Configurable |
static - Check static CRL none - Turn off CRL check | pkzipc -add -certificate="John Adams" -crl test.zip pkzipc -add -recipient="John Q.

cryptoptions Controls advanced encryption compatibility options. Makes possible a choice of support for smart cards or for certain other target scenarios when doing certificate-based encryption. Only affects encryption done using the recipient option. Configurable | FastAES – Enables the use of the fastest AES algorithm available, OpenSSL for AES over CryptoAPI. If FIPS 140 mode is enabled, this option is not effective. smartcard - Supports certificate-based encryption for recipients using smart cards, but produces encrypted files that cannot be decrypted by older versions of PKZIP. Turn off to support certificate-based encryption for recipients using versions of PKZIP prior to 6.1 at cost of support for smart cards. win2000 - Supports certificate-based encryption for recipients using smart cards or running on Windows NT or Windows 2000, but uses 3DES encryption to protect access to the key when encrypting with AES. Turn off to use no 3DES when encrypting with AES at cost of support for smart cards and recipients running Windows NT or Windows 2000. --------------------- –smartcard and win2000 sub-options are on by default. FastAES is not. | To configure FastAES on : pkzipc -config -cryptoptions=FastAES To turn off smartcard in a command line: pkzipc -add -cryptoptions=-smartcard -recipient="John Q.
