--before-date=mmddyyyy
|
-a
--ascii
[Systems using EBCDIC] Translate file to ASCII format.
|
-A
--adjust-sfx
Adjust self-extracting executable archive. A self-extracting executable archive is created by
prepending the SFX stub to an existing archive. The -A option tells zip to adjust the entry
offsets stored in the archive to take into account this "preamble" data.
Note: self-extracting archives for the Amiga are a special case. At present, only the Amiga port of zip
is capable of adjusting or updating these without corrupting them. -J can be used to remove the SFX stub
if other updates need to be made.
|
-AC
--archive-clear
[WIN32] Once archive is created (and tested if -T is used, which is recommended), clear the
archive bits of files processed. WARNING: Once the bits are cleared they are cleared. You may
want to use the -sf show files option to store the list of files processed in case the archive
operation must be repeated. Also consider using the -MM must match option. Be sure to check out
-DF as a possibly better way to do incremental backups.
|
-AS
--archive-set
[WIN32] Only include files that have the archive bit set. Directories are not stored when -AS is
used, though by default the paths of entries, including directories, are stored as usual and can
be used by most unzips to recreate directories.
The archive bit is set by the operating system when a file is modified and, if used with -AC, -AS
can provide an incremental backup capability. However, other applications can modify the archive
bit and it may not be a reliable indicator of which files have changed since the last archive
operation. Alternative ways to create incremental backups are using -t to use file dates, though
this won't catch old files copied to directories being archived, and -DF to create a differential
archive.
|
-B
--binary
[VM/CMS and MVS] force file to be read binary (default is text).
|
-Bn [TANDEM] set Edit/Enscribe formatting options with n defined as
bit 0: Don't add delimiter (Edit/Enscribe)
bit 1: Use LF rather than CR/LF as delimiter (Edit/Enscribe)
bit 2: Space fill record to maximum record length (Enscribe)
bit 3: Trim trailing space (Enscribe)
bit 8: Force 30K (Expand) large read for unstructured files
|
-b path
--temp-path path
Use the specified path for the temporary zip archive. For example:
zip -b /tmp stuff *
will put the temporary zip archive in the directory /tmp, copying over stuff.zip to the current
directory when done. This option is useful when updating an existing archive and the file system
containing this old archive does not have enough space to hold both old and new archives at the
same time. It may also be useful when streaming in some cases to avoid the need for data
descriptors. Note that using this option may require zip take additional time to copy the archive
file when done to the destination file system.
|
-c
--entry-comments
Add one-line comments for each file. File operations (adding, updating) are done first, and the
user is then prompted for a one-line comment for each file. Enter the comment followed by return,
or just return for no comment.
|
-C
--preserve-case
[VMS] Preserve case all on VMS. Negating this option (-C-) downcases.
|
-C2
--preserve-case-2
[VMS] Preserve case ODS2 on VMS. Negating this option (-C2-) downcases.
|
-C5
--preserve-case-5
[VMS] Preserve case ODS5 on VMS. Negating this option (-C5-) downcases.
|
-d
--delete
Remove (delete) entries from a zip archive. For example:
|
-db
--display-bytes
Display running byte counts showing the bytes zipped and the bytes to go.
|
-dc
--display-counts
Display running count of entries zipped and entries to go.
|
-dd
--display-dots
Display dots while each entry is zipped (except on ports that have their own progress indicator).
See -ds below for setting dot size. The default is a dot every 10 MB of input file processed.
The -v option also displays dots (previously at a much higher rate than this but now -v also
defaults to 10 MB) and this rate is also controlled by -ds.
|
-df
--datafork
[MacOS] Include only data-fork of files zipped into the archive. Good for exporting files to
foreign operating-systems. Resource-forks will be ignored at all.
|
-dg
--display-globaldots
Display progress dots for the archive instead of for each file. The command
zip -qdgds 10m
will turn off most output except dots every 10 MB.
|
-ds size
--dot-size size
Set amount of input file processed for each dot displayed. See -dd to enable displaying dots.
Setting this option implies -dd. Size is in the format nm where n is a number and m is a
multiplier. Currently m can be k (KB), m (MB), g (GB), or t (TB), so if n is 100 and m is k, size
would be 100k which is 100 KB. The default is 10 MB.
The -v option also displays dots and now defaults to 10 MB also. This rate is also controlled by
this option. A size of 0 turns dots off.
This option does not control the dots from the "Scanning files" message as zip scans for input
files. The dot size for that is fixed at 2 seconds or a fixed number of entries, whichever is
longer.
|
-du
--display-usize
Display the uncompressed size of each entry.
|
-dv
--display-volume
Display the volume (disk) number each entry is being read from, if reading an existing archive,
and being written to.
|
-D
--no-dir-entries
Do not create entries in the zip archive for directories. Directory entries are created by
default so that their attributes can be saved in the zip archive. The environment variable ZIPOPT
can be used to change the default options. For example under Unix with sh:
ZIPOPT="-D"; export ZIPOPT
(The variable ZIPOPT can be used for any option, including -i and -x using a new option format
detailed below, and can include several options.) The option -D is a shorthand for -x "*/" but the
latter previously could not be set as default in the ZIPOPT environment variable as the contents
of ZIPOPT gets inserted near the beginning of the command line and the file list had to end at the
end of the line.
This version of zip does allow -x and -i options in ZIPOPT if the form
|
-x file file ... @
is used, where the @ (an argument that is just @) terminates the list.
|
-DF
--difference-archive
Create an archive that contains all new and changed files since the original archive was created.
For this to work, the input file list and current directory must be the same as during the
original zip operation.
|
-e
--encrypt
Encrypt the contents of the zip archive using a password which is entered on the terminal in
response to a prompt (this will not be echoed; if standard error is not a tty, zip will exit with
an error). The password prompt is repeated to save the user from typing errors.
|
-E
--longnames
[OS/2] Use the .LONGNAME Extended Attribute (if found) as filename.
|
-f
--freshen
Replace (freshen) an existing entry in the zip archive only if it has been modified more recently
than the version already in the zip archive; unlike the update option (-u) this will not add files
that are not already in the zip archive. For example:
|
-F
--fix
-FF
--fixfix
Fix the zip archive. The -F option can be used if some portions of the archive are missing, but
requires a reasonably intact central directory. The input archive is scanned as usual, but zip
will ignore some problems. The resulting archive should be valid, but any inconsistent entries
will be left out.
|
-FI
--fifo [Unix] Normally zip skips reading any FIFOs (named pipes) encountered, as zip can hang if the
FIFO is not being fed. This option tells zip to read the contents of any FIFO it finds.
|
-FS
--filesync
Synchronize the contents of an archive with the files on the OS. Normally when an archive is
updated, new files are added and changed files are updated but files that no longer exist on the
OS are not deleted from the archive. This option enables a new mode that checks entries in the
archive against the file system. If the file time and file size of the entry matches that of the
OS file, the entry is copied from the old archive instead of being read from the file system and
compressed. If the OS file has changed, the entry is read and compressed as usual. If the entry
in the archive does not match a file on the OS, the entry is deleted. Enabling this option should
create archives that are the same as new archives, but since existing entries are copied instead
of compressed, updating an existing archive with -FS can be much faster than creating a new
archive. Also consider using -u for updating an archive.
For this option to work, the archive should be updated from the same directory it was created in
so the relative paths match. If few files are being copied from the old archive, it may be faster
to create a new archive instead.
Note that the timezone environment variable TZ should be set according to the local timezone in
order for this option to work correctly. A change in timezone since the original archive was
created could result in no times matching and recompression of all files.
This option deletes files from the archive. If you need to preserve the original archive, make a
copy of the archive first or use the --out option to output the updated archive to a new file.
Even though it may be slower, creating a new archive with a new archive name is safer, avoids
mismatches between archive and OS paths, and is preferred.
|
-g
--grow
Grow (append to) the specified zip archive, instead of creating a new one. If this operation
fails, zip attempts to restore the archive to its original state. If the restoration fails, the
archive might become corrupted. This option is ignored when there's no existing archive or when at
least one archive member must be updated or deleted.
|
-h
-?
--help
Display the zip help information (this also appears if zip is run with no arguments).
|
-h2
--more-help
Display extended help including more on command line format, pattern matching, and more obscure
options.
|
-i files
--include files
Include only the specified files, as in:
|
-I
--no-image
[Acorn RISC OS] Don't scan through Image files. When used, zip will not consider Image files (eg.
DOS partitions or Spark archives when SparkFS is loaded) as directories but will store them as
single files.
For example, if you have SparkFS loaded, zipping a Spark archive will result in a zipfile
containing a directory (and its content) while using the 'I' option will result in a zipfile
containing a Spark archive. Obviously this second case will also be obtained (without the 'I'
option) if SparkFS isn't loaded.
|
-ic
--ignore-case
[VMS, WIN32] Ignore case when matching archive entries. This option is only available on systems
where the case of files is ignored. On systems with case-insensitive file systems, case is
normally ignored when matching files on the file system but is not ignored for -f (freshen), -d
(delete), -U (copy), and similar modes when matching against archive entries (currently -f ignores
case on VMS) because archive entries can be from systems where case does matter and names that are
the same except for case can exist in an archive. The -ic option makes all matching case
insensitive. This can result in multiple archive entries matching a command line pattern.
|
-j
--junk-paths
Store just the name of a saved file (junk the path), and do not store directory names. By default,
zip will store the full path (relative to the current directory).
|
-jj
--absolute-path
[MacOS] record Fullpath (+ Volname). The complete path including volume will be stored. By default
the relative path will be stored.
|
-J
--junk-sfx
Strip any prepended data (e.g. a SFX stub) from the archive.
|
-k
--DOS-names
Attempt to convert the names and paths to conform to MSDOS, store only the MSDOS attribute (just
the user write attribute from Unix), and mark the entry as made under MSDOS (even though it was
not); for compatibility with PKUNZIP under MSDOS which cannot handle certain names such as those
with two dots.
|
-l
--to-crlf
Translate the Unix end-of-line character LF into the MSDOS convention CR LF. This option should
not be used on binary files. This option can be used on Unix if the zip file is intended for
PKUNZIP under MSDOS. If the input files already contain CR LF, this option adds an extra CR. This
is to ensure that unzip -a on Unix will get back an exact copy of the original file, to undo the
effect of zip -l. See -ll for how binary files are handled.
|
-la
--log-append
Append to existing logfile. Default is to overwrite.
|
-lf logfilepath
--logfile-path logfilepath
Open a logfile at the given path. By default any existing file at that location is overwritten,
but the -la option will result in an existing file being opened and the new log information
appended to any existing information. Only warnings and errors are written to the log unless the
-li option is also given, then all information messages are also written to the log.
|
-li
--log-info
Include information messages, such as file names being zipped, in the log. The default is to only
include the command line, any warnings and errors, and the final status.
|
-ll
--from-crlf
Translate the MSDOS end-of-line CR LF into Unix LF. This option should not be used on binary
files. This option can be used on MSDOS if the zip file is intended for unzip under Unix. If the
file is converted and the file is later determined to be binary a warning is issued and the file
is probably corrupted. In this release if -ll detects binary in the first buffer read from a
file, zip now issues a warning and skips line end conversion on the file. This check seems to
catch all binary files tested, but the original check remains and if a converted file is later
determined to be binary that warning is still issued. A new algorithm is now being used for
binary detection that should allow line end conversion of text files in UTF-8 and similar
encodings.
|
-L
--license
Display the zip license.
|
-m
--move
Move the specified files into the zip archive; actually, this deletes the target directories/files
after making the specified zip archive. If a directory becomes empty after removal of the files,
the directory is also removed. No deletions are done until zip has created the archive without
error. This is useful for conserving disk space, but is potentially dangerous so it is
recommended to use it in combination with -T to test the archive before removing all input files.
|
-MM
--must-match
All input patterns must match at least one file and all input files found must be readable.
Normally when an input pattern does not match a file the "name not matched" warning is issued and
when an input file has been found but later is missing or not readable a missing or not readable
warning is issued. In either case zip continues creating the archive, with missing or unreadable
new files being skipped and files already in the archive remaining unchanged. After the archive
is created, if any files were not readable zip returns the OPEN error code (18 on most systems)
instead of the normal success return (0 on most systems). With -MM set, zip exits as soon as an
input pattern is not matched (whenever the "name not matched" warning would be issued) or when an
input file is not readable. In either case zip exits with an OPEN error and no archive is
created.
This option is useful when a known list of files is to be zipped so any missing or unreadable
files will result in an error. It is less useful when used with wildcards, but zip will still
exit with an error if any input pattern doesn't match at least one file and if any matched files
are unreadable. If you want to create the archive anyway and only need to know if files were
skipped, don't use -MM and just check the return code. Also -lf could be useful.
|
-n suffixes
--suffixes suffixes
Do not attempt to compress files named with the given suffixes. Such files are simply stored (0%
compression) in the output zip file, so that zip doesn't waste its time trying to compress them.
The suffixes are separated by either colons or semicolons. For example:
|
-nw
--no-wild
Do not perform internal wildcard processing (shell processing of wildcards is still done by the
shell unless the arguments are escaped). Useful if a list of paths is being read and no wildcard
substitution is desired.
|
-N
--notes
[Amiga, MacOS] Save Amiga or MacOS filenotes as zipfile comments. They can be restored by using
the -N option of unzip. If -c is used also, you are prompted for comments only for those files
that do not have filenotes.
|
-o
--latest-time
Set the "last modified" time of the zip archive to the latest (oldest) "last modified" time found
among the entries in the zip archive. This can be used without any other operations, if desired.
For example:
zip -o foo
will change the last modified time of foo.zip to the latest time of the entries in foo.zip.
|
-O output-file
--output-file output-file
Process the archive changes as usual, but instead of updating the existing archive, output the new
archive to output-file. Useful for updating an archive without changing the existing archive and
the input archive must be a different file than the output archive.
|
-p
--paths
Include relative file paths as part of the names of files stored in the archive. This is the
default. The -j option junks the paths and just stores the names of the files.
|
-P password
--password password
Use password to encrypt zipfile entries (if any). THIS IS INSECURE! Many multi-user operating
systems provide ways for any user to see the current command line of any other user; even on
stand-alone systems there is always the threat of over-the-shoulder peeking. Storing the
plaintext password as part of a command line in an automated script is even worse. Whenever
possible, use the non-echoing, interactive prompt to enter passwords. (And where security is
truly important, use strong encryption such as Pretty Good Privacy instead of the relatively weak
standard encryption provided by zipfile utilities.)
|
-q
--quiet
Quiet mode; eliminate informational messages and comment prompts. (Useful, for example, in shell
scripts and background tasks).
|
-Qn
--Q-flag n
[QDOS] store information about the file in the file header with n defined as
bit 0: Don't add headers for any file
bit 1: Add headers for all files
bit 2: Don't wait for interactive key press on exit
|
-r
--recurse-paths
Travel the directory structure recursively; for example:
|
-R
--recurse-patterns
Travel the directory structure recursively starting at the current directory; for example:
|
-RE
--regex
[WIN32] Before zip 3.0, regular expression list matching was enabled by default on Windows
platforms. Because of confusion resulting from the need to escape "[" and "]" in names, it is now
off by default for Windows so "[" and "]" are just normal characters in names. This option
enables [] matching again.
|
-s splitsize
--split-size splitsize
Enable creating a split archive and set the split size. A split archive is an archive that could
be split over many files. As the archive is created, if the size of the archive reaches the
specified split size, that split is closed and the next split opened. In general all splits but
the last will be the split size and the last will be whatever is left. If the entire archive is
smaller than the split size a single-file archive is created.
|
-sb
--split-bell
If splitting and using split pause mode, ring the bell when zip pauses for each split destination.
|
-sc
--show-command
Show the command line starting zip as processed and exit. The new command parser permutes the
arguments, putting all options and any values associated with them before any non-option
arguments. This allows an option to appear anywhere in the command line as long as any values
that go with the option go with it. This option displays the command line as zip sees it,
including any arguments from the environment such as from the ZIPOPT variable. Where allowed,
options later in the command line can override options earlier in the command line.
|
-sf
--show-files
Show the files that would be operated on, then exit. For instance, if creating a new archive,
this will list the files that would be added. If the option is negated, -sf-, output only to an
open log file. Screen display is not recommended for large lists.
|
-so
--show-options
Show all available options supported by zip as compiled on the current system. As this command
reads the option table, it should include all options. Each line includes the short option (if
defined), the long option (if defined), the format of any value that goes with the option, if the
option can be negated, and a small description. The value format can be no value, required value,
optional value, single character value, number value, or a list of values. The output of this
option is not intended to show how to use any option but only show what options are available.
|
-sp
--split-pause
If splitting is enabled with -s, enable split pause mode. This creates split archives as -s does,
but stream writing is used so each split can be closed as soon as it is written and zip will pause
between each split to allow changing split destination or media.
Though this split mode allows writing splits directly to removable media, it uses stream archive
format that may not be readable by some unzips. Before relying on splits created with -sp, test a
split archive with the unzip you will be using.
To convert a stream split archive (created with -sp) to a standard archive see the --out option.
|
-su
--show-unicode
As -sf, but also show Unicode version of the path if exists.
|
-sU
--show-just-unicode
As -sf, but only show Unicode version of the path if exists, otherwise show the standard version
of the path.
|
-sv
--split-verbose
Enable various verbose messages while splitting, showing how the splitting is being done.
|
-S
--system-hidden
[MSDOS, OS/2, WIN32 and ATARI] Include system and hidden files.
[MacOS] Includes finder invisible files, which are ignored otherwise.
|
-t mmddyyyy
--from-date mmddyyyy
Do not operate on files modified prior to the specified date, where mm is the month (00-12), dd is
the day of the month (01-31), and yyyy is the year. The ISO 8601 date format yyyy-mm-dd is also
accepted. For example:
zip -rt 12071991 infamy foo
zip -rt 1991-12-07 infamy foo
will add all the files in foo and its subdirectories that were last modified on or after 7
December 1991, to the zip archive infamy.zip.
|
-tt mmddyyyy
--before-date mmddyyyy
Do not operate on files modified after or at the specified date, where mm is the month (00-12), dd
is the day of the month (01-31), and yyyy is the year. The ISO 8601 date format yyyy-mm-dd is
also accepted. For example:
zip -rtt 11301995 infamy foo
zip -rtt 1995-11-30 infamy foo
will add all the files in foo and its subdirectories that were last modified before 30 November
1995, to the zip archive infamy.zip.
|
-T
--test
Test the integrity of the new zip file. If the check fails, the old zip file is unchanged and
(with the -m option) no input files are removed.
|
-TT cmd
--unzip-command cmd
Use command cmd instead of 'unzip -tqq' to test an archive when the -T option is used. On Unix,
to use a copy of unzip in the current directory instead of the standard system unzip, could use:
zip archive file1 file2 -T -TT "./unzip -tqq"
In cmd, {} is replaced by the name of the temporary archive, otherwise the name of the archive is
appended to the end of the command. The return code is checked for success (0 on Unix).
|
-u
--update
Replace (update) an existing entry in the zip archive only if it has been modified more recently
than the version already in the zip archive. For example:
zip -u stuff *
will add any new files in the current directory, and update any files which have been modified
since the zip archive stuff.zip was last created/modified (note that zip will not try to pack
stuff.zip into itself when you do this).
Note that the -u option with no input file arguments acts like the -f (freshen) option.
|
-U
--copy-entries
Copy entries from one archive to another. Requires the --out option to specify a different output
file than the input archive. Copy mode is the reverse of -d delete. When delete is being used
with --out, the selected entries are deleted from the archive and all other entries are copied to
the new archive, while copy mode selects the files to include in the new archive. Unlike -u
update, input patterns on the command line are matched against archive entries only and not the
file system files. For instance,
|
-UN v
--unicode v
Determine what zip should do with Unicode file names. zip 3.0, in addition to the standard file
path, now includes the UTF-8 translation of the path if the entry path is not entirely 7-bit
ASCII. When an entry is missing the Unicode path, zip reverts back to the standard file path.
The problem with using the standard path is this path is in the local character set of the zip
that created the entry, which may contain characters that are not valid in the character set being
used by the unzip. When zip is reading an archive, if an entry also has a Unicode path, zip now
defaults to using the Unicode path to recreate the standard path using the current local character
set.
|
-v
--verbose
Verbose mode or print diagnostic version info.
Normally, when applied to real operations, this option enables the display of a progress indicator
during compression (see -dd for more on dots) and requests verbose diagnostic info about zipfile
structure oddities.
However, when -v is the only command line argument a diagnostic screen is printed instead. This
should now work even if stdout is redirected to a file, allowing easy saving of the information
for sending with bug reports to Info-ZIP. The version screen provides the help screen header with
program name, version, and release date, some pointers to the Info-ZIP home and distribution
sites, and shows information about the target environment (compiler type and version, OS version,
compilation date and the enabled optional features used to create the zip executable).
|
-V
--VMS-portable
[VMS] Save VMS file attributes. (Files are truncated at EOF.) When a -V archive is unpacked on
a non-VMS system, some file types (notably Stream_LF text files and pure binary files like
fixed-512) should be extracted intact. Indexed files and file types with embedded record sizes
(notably variable-length record types) will probably be seen as corrupt elsewhere.
|
-VV
--VMS-specific
[VMS] Save VMS file attributes, and all allocated blocks in a file, including any data beyond
EOF. Useful for moving ill-formed files among VMS systems. When a -VV archive is unpacked on
a non-VMS system, almost all files will appear corrupt.
|
-w
--VMS-versions
[VMS] Append the version number of the files to the name, including multiple versions of files.
Default is to use only the most recent version of a specified file.
|
-ww
--VMS-dot-versions
[VMS] Append the version number of the files to the name, including multiple versions of files,
using the .nnn format. Default is to use only the most recent version of a specified file.
|
-ws
--wild-stop-dirs
Wildcards match only at a directory level. Normally zip handles paths as strings and given the
paths
|
-x files
--exclude files
Explicitly exclude the specified files, as in:
|
-X
--no-extra
Do not save extra file attributes (Extended Attributes on OS/2, uid/gid and file times on Unix).
The zip format uses extra fields to include additional information for each entry. Some extra
fields are specific to particular systems while others are applicable to all systems. Normally
when zip reads entries from an existing archive, it reads the extra fields it knows, strips the
rest, and adds the extra fields applicable to that system. With -X, zip strips all old fields and
only includes the Unicode and Zip64 extra fields (currently these two extra fields cannot be
disabled).
Negating this option, -X-, includes all the default extra fields, but also copies over any
unrecognized extra fields.
|
-y
--symlinks
For UNIX and VMS (V8.3 and later), store symbolic links as such in the zip archive, instead of
compressing and storing the file referred to by the link. This can avoid multiple copies of files
being included in the archive as zip recurses the directory trees and accesses files directly and
by links.
|
-z
--archive-comment
Prompt for a multi-line comment for the entire zip archive. The comment is ended by a line
containing just a period, or an end of file condition (^D on Unix, ^Z on MSDOS, OS/2, and VMS).
The comment can be taken from a file:
zip -z foo < foowhat
|
-Z cm
--compression-method cm
Set the default compression method. Currently the main methods supported by zip are store and
deflate. Compression method can be set to:
|
-#
(-0, -1, -2, -3, -4, -5, -6, -7, -8, -9)
Regulate the speed of compression using the specified digit #, where -0 indicates no compression
(store all files), -1 indicates the fastest compression speed (less compression) and -9 indicates
the slowest compression speed (optimal compression, ignores the suffix list). The default
compression level is -6.
Though still being worked, the intention is this setting will control compression speed for all
compression methods. Currently only deflation is controlled.
