How Do I Unzip Files On A Mac

WinZip can encrypt files while you create new Zip files (.zip or.zipx) and it can also add encryption to data in existing Zip files. Encrypt while creating Zip files. WinZip in the Default view: Click the Encrypt toggle in the Actions pane; If you have not already done so, click the Options button that now displays in the Actions pane to set. A zip file takes one or more files and folders on your computer, joins them into one file for convenience sake and compresses them to save storage space. Modern operating systems, including Microsoft Windows and Apple macOS, have built-in support for zip files, so you can open them and create them without any special tools. WinZip is the world's #1 choice when working with large files – zip, unzip, protect, share and more. Zip and unzip files instantly; Protect files with banking-level AES encryption; Share directly to iCloud Drive, Dropbox, Google Drive and ZipShare, from within WinZip; Download Trial It's free, go for it Buy Now Starts at. With WinZip for Mac 2.0 or later, you can right-click (or press CTRL and click) your saved RAR files and use the Context Menu to unzip them. Click on Services at the bottom of the Context menu, then choose Unzip.

ZIP files can contain multiple files of different types. Common files that can be included in a ZIP archive include PDFs, images, videos, and Microsoft Office documents including Microsoft Word, Microsoft Excel, and Microsoft PowerPoint (.DOCX,.XLSX,.PPTX file formats).

zip - package and compress (archive) files

Synopsis

zip [-aABcdDeEfFghjklLmoqrRSTuvVwXyz!@$] [--longoption ...] [-b path] [-n suffixes] [-t date] [-tt date][zipfile [file ...]] [-xi list]

zipcloak (see separate man page)

zipsplit (see separate man page)

Note: Command line processing in zip has been changed to support long options and handle all options and arguments more consistently. Some oldcommand lines that depend on command line inconsistencies may no longer work.

Description

zip is a compression and file packaging utility for Unix, VMS, MSDOS, OS/2, Windows 9x/NT/XP, Minix, Atari, Macintosh, Amiga, and Acorn RISC OS. Itis analogous to a combination of the Unix commands tar(1) and compress(1) and is compatible with PKZIP (Phil Katz's ZIP for MSDOS systems).

A companion program (unzip(1L)) unpacks zip archives. The zip and unzip(1L) programs can work with archives produced by PKZIP(supporting most PKZIP features up to PKZIP version 4.6), and PKZIP and PKUNZIP can work with archives produced by zip (with some exceptions, notablystreamed archives, but recent changes in the zip file standard may facilitate better compatibility). zip version 3.0 is compatible with PKZIP 2.04 andalso supports the Zip64 extensions of PKZIP 4.5 which allow archives as well as files to exceed the previous 2 GB limit (4 GB in some cases). zip alsonow supports bzip2 compression if the bzip2 library is included when zip is compiled. Note that PKUNZIP 1.10 cannot extract files producedby PKZIP 2.04 or zip 3.0. You must use PKUNZIP 2.04g or unzip 5.0p1 (or later versions) to extract them.

See the EXAMPLES section at the bottom of this page for examples of some typical uses of zip.

Large Archives and Zip64.zip automatically uses the Zip64 extensions when files larger than 4 GB are added to an archive, an archivecontaining Zip64 entries is updated (if the resulting archive still needs Zip64), the size of the archive will exceed 4 GB, or when the number of entries inthe archive will exceed about 64K. Zip64 is also used for archives streamed from standard input as the size of such archives are not known in advance, but theoption -fz- can be used to force zip to create PKZIP 2 compatible archives (as long as Zip64 extensions are not needed). You must use a PKZIP 4.5compatible unzip, such as unzip 6.0 or later, to extract files using the Zip64 extensions.

In addition, streamed archives, entries encrypted with standard encryption, or split archives created with the pause option may not be compatible with PKZIPas data descriptors are used and PKZIP at the time of this writing does not support data descriptors (but recent changes in the PKWare published zip standardnow include some support for the data descriptor format zip uses).

Mac OS X. Though previous Mac versions had their own zip port, zip supports Mac OS X as part of the Unix port and most Unix featuresapply. References to 'MacOS' below generally refer to MacOS versions older than OS X. Support for some Mac OS features in the Unix Mac OS X port, such asresource forks, is expected in the next zip release.

For a brief help on zip and unzip, run each without specifying any parameters on the command line.

Use

The program is useful for packaging a set of files for distribution; for archiving files; and for saving disk space by temporarily compressing unused filesor directories.

The zip program puts one or more compressed files into a single zip archive, along with information about the files (name, path, date, time oflast modification, protection, and check information to verify file integrity). An entire directory structure can be packed into a zip archive with asingle command. Compression ratios of 2:1 to 3:1 are common for text files. zip has one compression method (deflation) and can also store files withoutcompression. (If bzip2 support is added, zip can also compress using bzip2 compression, but such entries require a reasonably modern unzipto decompress. When bzip2 compression is selected, it replaces deflation as the default method.) zip automatically chooses the better of the two(deflation or store or, if bzip2 is selected, bzip2 or store) for each file to be compressed.

Command format. The basic command format is

zip options archive inpath inpath ...

where archive is a new or existing zip archive and inpath is a directory or file path optionally including wildcards. When given thename of an existing zip archive, zip will replace identically named entries in the zip archive (matching the relative names as stored inthe archive) or add entries for new names. For example, if foo.zip exists and contains foo/file1 and foo/file2, and the directoryfoo contains the files foo/file1 and foo/file3, then:

zip -r foo.zip foo

or more concisely

zip -r foo foo

will replace foo/file1 in foo.zip and add foo/file3 to foo.zip. After this, foo.zip contains foo/file1,foo/file2, and foo/file3, with foo/file2 unchanged from before.

So if before the zip command is executed foo.zip has:

foo/file1 foo/file2

and directory foo has:

file1 file3

then foo.zip will have:

foo/file1 foo/file2 foo/file3

where foo/file1 is replaced and foo/file3 is new.

-@ file lists. If a file list is specified as -@ [Not on MacOS], zip takes the list of input files from standard input instead of fromthe command line. For example,

zip -@ foo

will store the files listed one per line on stdin in foo.zip.

Under Unix, this option can be used to powerful effect in conjunction with the find (1) command. For example, to archive all the C source files inthe current directory and its subdirectories:

find . -name '*.[ch]' -print | zip source -@

(note that the pattern must be quoted to keep the shell from expanding it).

Streaming input and output.zip will also accept a single dash ('-') as the zip file name, in which case it will write the zip file tostandard output, allowing the output to be piped to another program. For example:

zip -r - . | dd of=/dev/nrst0 obs=16k

would write the zip output directly to a tape with the specified block size for the purpose of backing up the current directory.

zip also accepts a single dash ('-') as the name of a file to be compressed, in which case it will read the file from standard input, allowing zip totake input from another program. For example:

tar cf - . | zip backup -

would compress the output of the tar command for the purpose of backing up the current directory. This generally produces better compression than theprevious example using the -r option because zip can take advantage of redundancy between files. The backup can be restored using the command

unzip -p backup | tar xf -

When no zip file name is given and stdout is not a terminal, zip acts as a filter, compressing standard input to standard output. Forexample,

tar cf - . | zip | dd of=/dev/nrst0 obs=16k

is equivalent to

tar cf - . | zip - - | dd of=/dev/nrst0 obs=16k

zip archives created in this manner can be extracted with the program funzip which is provided in the unzip package, or bygunzip which is provided in the gzip package (but some gunzip may not support this if zip used the Zip64 extensions). Forexample:

dd if=/dev/nrst0 ibs=16k | funzip | tar xvf -

The stream can also be saved to a file and unzip used.

If Zip64 support for large files and archives is enabled and zip is used as a filter, zip creates a Zip64 archive that requires a PKZIP 4.5 orlater compatible unzip to read it. This is to avoid amgibuities in the zip file structure as defined in the current zip standard (PKWARE AppNote) where thedecision to use Zip64 needs to be made before data is written for the entry, but for a stream the size of the data is not known at that point. If the data isknown to be smaller than 4 GB, the option -fz- can be used to prevent use of Zip64, but zip will exit with an error if Zip64 was in fact needed.zip 3 and unzip 6 and later can read archives with Zip64 entries. Also, zip removes the Zip64 extensions if not needed when archiveentries are copied (see the -U (--copy) option).

When directing the output to another file, note that all options should be before the redirection including -x. For example:

zip archive '*.h' '*.c' -x donotinclude.h orthis.h > tofile

Zip files. When changing an existing zip archive, zip will write a temporary file with the new contents, and only replace the old onewhen the process of creating the new version has been completed without error.

If the name of the zip archive does not contain an extension, the extension .zip is added. If the name already contains an extension otherthan .zip, the existing extension is kept unchanged. However, split archives (archives split over multiple files) require the .zip extension onthe last split.

Scanning and reading files. When zip starts, it scans for files to process (if needed). If this scan takes longer than about 5 seconds,zip will display a 'Scanning files' message and start displaying progress dots every 2 seconds or every so many entries processed, whichever takeslonger. If there is more than 2 seconds between dots it could indicate that finding each file is taking time and could mean a slow network connection forexample. (Actually the initial file scan is a two-step process where the directory scan is followed by a sort and these two steps are separated with a space inthe dots. If updating an existing archive, a space also appears between the existing file scan and the new file scan.) The scanning files dots are notcontrolled by the -ds dot size option, but the dots are turned off by the -q quiet option. The -sf show files option can be used to scanfor files and get the list of files scanned without actually processing them.

If zip is not able to read a file, it issues a warning but continues. See the -MM option below for more on how zip handles patternsthat are not matched and files that are not readable. If some files were skipped, a warning is issued at the end of the zip operation noting how many fileswere read and how many skipped.

Command modes.zip now supports two distinct types of command modes, external and internal. The external modes (add,update, and freshen) read files from the file system (as well as from an existing archive) while the internal modes (delete and copy) operateexclusively on entries in an existing archive.

add

Update existing entries and add new files. If the archive does not exist create it. This is the default mode.

update (-u)

Update existing entries if newer on the file system and add new files. If the archive does not exist issue warning then create a new archive.

freshen (-f)

Update existing entries of an archive if newer on the file system. Does not add new files to the archive.

delete (-d)

Select entries in an existing archive and delete them.

copy (-U)

Select entries in an existing archive and copy them to a new archive. This new mode is similar to update but command line patterns select entries inthe existing archive rather than files from the file system and it uses the --out option to write the resulting archive to a new file rather than updatethe existing archive, leaving the original archive unchanged.

The new File Sync option (-FS) is also considered a new mode, though it is similar to update. This mode synchronizes the archive with thefiles on the OS, only replacing files in the archive if the file time or size of the OS file is different, adding new files, and deleting entries from thearchive where there is no matching file. As this mode can delete entries from the archive, consider making a backup copy of the archive.

Also see -DF for creating difference archives.

See each option description below for details and the EXAMPLES section below for examples.

Split archives.zip version 3.0 and later can create split archives. A split archive is a standard zip archive split over multiplefiles. (Note that split archives are not just archives split in to pieces, as the offsets of entries are now based on the start of each split. Concatenatingthe pieces together will invalidate these offsets, but unzip can usually deal with it. zip will usually refuse to process such a spliced archiveunless the -FF fix option is used to fix the offsets.)

One use of split archives is storing a large archive on multiple removable media. For a split archive with 20 split files the files are typically named(replace ARCHIVE with the name of your archive) ARCHIVE.z01, ARCHIVE.z02, ..., ARCHIVE.z19, ARCHIVE.zip. Note that the last file is the .zip file. Incontrast, spanned archives are the original multi-disk archive generally requiring floppy disks and using volume labels to store disk numbers.zip supports split archives but not spanned archives, though a procedure exists for converting split archives of the right size to spanned archives. Thereverse is also true, where each file of a spanned archive can be copied in order to files with the above names to create a split archive.

Use -s to set the split size and create a split archive. The size is given as a number followed optionally by one of k (kB), m (MB), g (GB), or t(TB) (the default is m). The -sp option can be used to pause zip between splits to allow changing removable media, for example, but read thedescriptions and warnings for both -s and -sp below.

Though zip does not update split archives, zip provides the new option -O (--output-file or --out) to allow splitarchives to be updated and saved in a new archive. For example,

zip inarchive.zip foo.c bar.c --out outarchive.zip

reads archive inarchive.zip, even if split, adds the files foo.c and bar.c, and writes the resulting archive to outarchive.zip.If inarchive.zip is split then outarchive.zip defaults to the same split size. Be aware that if outarchive.zip and any split files thatare created with it already exist, these are always overwritten as needed without warning. This may be changed in the future.

Unicode. Though the zip standard requires storing paths in an archive using a specific character set, in practice zips have stored paths in archivesin whatever the local character set is. This creates problems when an archive is created or updated on a system using one character set and then extracted onanother system using a different character set. When compiled with Unicode support enabled on platforms that support wide characters, zip now stores, inaddition to the standard local path for backward compatibility, the UTF-8 translation of the path. This provides a common universal character set for storingpaths that allows these paths to be fully extracted on other systems that support Unicode and to match as close as possible on systems that don't.

On Win32 systems where paths are internally stored as Unicode but represented in the local character set, it's possible that some paths will be skippedduring a local character set directory scan. zip with Unicode support now can read and store these paths. Note that Win 9x systems and FAT file systemsdon't fully support Unicode.

Be aware that console windows on Win32 and Unix, for example, sometimes don't accurately show all characters due to how each operating system switches incharacter sets for display. However, directory navigation tools should show the correct paths if the needed fonts are loaded.

Command line format. This version of zip has updated command line processing and support for long options.

Short options take the form

-s[-][s[-]...][value][=value][ value]

where s is a one or two character short option. A short option that takes a value is last in an argument and anything after it is taken as the value. If theoption can be negated and '-' immediately follows the option, the option is negated. Short options can also be given as separate arguments

-s[-][value][=value][ value] -s[-][value][=value][ value] ...

Short options in general take values either as part of the same argument or as the following argument. An optional = is also supported. So

-ttmmddyyyy

and

-tt=mmddyyyy

and

-tt mmddyyyy

all work. The -x and -i options accept lists of values and use a slightly different format described below. See the -x and -ioptions.

Long options take the form

--longoption[-][=value][ value]

where the option starts with --, has a multicharacter name, can include a trailing dash to negate the option (if the option supports it), and can have avalue (option argument) specified by preceeding it with = (no spaces). Values can also follow the argument. So

--before-date=mmddyyyy

and

--before-date mmddyyyy

both work.

Long option names can be shortened to the shortest unique abbreviation. See the option descriptions below for which support long options. To avoidconfusion, avoid abbreviating a negatable option with an embedded dash ('-') at the dash if you plan to negate it (the parser would consider a trailing dash,such as for the option --some-option using --some- as the option, as part of the name rather than a negating dash). This may be changed to forcethe last dash in --some- to be negating in the future.

Options

-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 -Aoption 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 thesewithout 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 bitsare 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 berepeated. 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 backupcapability. However, other applications can modify the archive bit and it may not be a reliable indicator of which files have changed since the last archiveoperation. Alternative ways to create incremental backups are using -t to use file dates, though this won't catch old files copied to directories beingarchived, 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 remove the entry foo/tom/junk, all of the files that start with foo/harry/, and all of the files that end with .o (in any path).Note that shell pathname expansion has been inhibited with backslashes, so that zip can see the asterisks, enabling zip to match on the contentsof the zip archive instead of the contents of the current directory. (The backslashes are not used on MSDOS-based platforms.) Can also use quotes toescape the asterisks as in

zip -d foo foo/tom/junk 'foo/harry/*' '*.o'

Not escaping the asterisks on a system where the shell expands wildcards could result in the asterisks being converted to a list of files in the currentdirectory and that list used to delete entries from the archive.

Under MSDOS, -d is case sensitive when it matches names in the zip archive. This requires that file names be entered in upper case if theywere zipped by PKZIP on an MSDOS system. (We considered making this case insensitive on systems where paths were case insensitive, but it is possible thearchive came from a system where case does matter and the archive could include both Bar and bar as separate files in the archive.) But see thenew option -ic to ignore case in the archive.

-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 isa 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 defaultsto 10 MB) and this rate is also controlled by -ds.

-df

--datafork

[MacOS] Include only>

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 theformat 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 whichis 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 ora 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 ziparchive. 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 severaloptions.) The option -D is a shorthand for -x '*/' but the latter previously could not be set as default in the ZIPOPT environment variable asthe 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 currentdirectory must be the same as during the original zip operation.

For example, if the existing archive was created using

zip -r foofull .

-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 centraldirectory. The input archive is scanned as usual, but zip will ignore some problems. The resulting archive should be valid, but any inconsistent entrieswill be left out.
--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 butfiles 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 filesystem. 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 filesystem 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, theentry 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.
-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 itsoriginal state. If the restoration fails, the archive might become corrupted. This option is ignored when there's no existing archive or when at least onearchive member must be updated or deleted.
--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
-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 withcase-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), andsimilar modes when matching against archive entries (currently -f ignores case on VMS) because archive entries can be from systems where case does matter andnames 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 archiveentries 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 thecurrent 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 asmade 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 Unixif 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 filebeing opened and the new log information appended to any existing information. Only warnings and errors are written to the log unless the -li option isalso 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 thefinal 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 isintended 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 isstill issued. A new algorithm is now being used for binary detection that should allow line end conversion of text files in UTF-8 and similarencodings.
-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. Ifa directory becomes empty after removal of the files, the directory is also removed. No deletions are done until zip has created the archive withouterror. 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 archivebefore 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 'namenot 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. Ineither 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 usedwith 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. Ifyou 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 couldbe 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 thatzip doesn't waste its time trying to compress them. The suffixes are separated by either colons or semicolons. For example:
