Zip 3.0 (July 5th 2008). Usage: zip [-options] [-b path] [-t mmddyyyy] [-n suffixes] [zipfile list] [-xi = list] The default action is to add or replace zipfile entries from list, = which can include the special name - to compress standard input. If zipfile and list are omitted, zip compresses stdin to stdout. -f freshen: only changed files -u update: only changed or new = files -d delete entries in zipfile -m move into zipfile (delete OS = files) -r recurse into directories -j junk (don't record) directory = names -0 store only -l convert LF to CR LF (-ll CR LF = to LF) -1 compress faster -9 compress better -q quiet operation -v verbose operation/print version = info -c add one-line comments -z add zipfile comment -@ read names from stdin -o make zipfile as old as latest = entry -x exclude the following names -i include only the following = names -F fix zipfile (-FF try harder) -D do not add directory entries -A adjust self-extracting exe -J junk zipfile prefix (unzipsfx) -T test zipfile integrity -X eXclude eXtra file attributes -y store symbolic links as the link instead of the referenced file -e encrypt -n don't compress these suffixes -h2 show more help =20 bash$ zip -h2 Extended Help for Zip See the Zip Manual for more detailed help Zip stores files in zip archives. The default action is to add or = replace zipfile entries. Basic command line: zip options archive_name file file ... Some examples: Add file.txt to z.zip (create z if needed): zip z file.txt Zip all files in current dir: zip z * Zip files in current dir and subdirs also: zip -r z . Basic modes: External modes (selects files from file system): add - add new files/update existing files in archive = (default) -u update - add new files/update existing files only if later = date -f freshen - update existing files only (no files added) -FS filesync - update if date or size changed, delete if no OS match Internal modes (selects entries in archive): -d delete - delete files from archive (see below) -U copy - select files in archive to copy (use with --out) Basic options: -r recurse into directories (see Recursion below) -m after archive created, delete original files (move into = archive) -j junk directory names (store just file names) -q quiet operation -v verbose operation (just "zip -v" shows version information) -c prompt for one-line comment for each entry -z prompt for comment for archive (end with just "." line or = EOF) -@ read names to zip from stdin (one path per line) -o make zipfile as old as latest entry Syntax: The full command line syntax is: zip [-shortopts ...] [--longopt ...] [zipfile [path path ...]] [-xi = list] Any number of short option and long option arguments are allowed (within limits) as well as any number of path arguments for files to zip up. If zipfile exists, the archive is read in. If zipfile is "-", stream to stdout. If any path is "-", zip stdin. Options and Values: For short options that take values, use -ovalue or -o value or = -o=3Dvalue For long option values, use either --longoption=3Dvalue or = --longoption value For example: zip -ds 10 --temp-dir=3Dpath zipfile path1 path2 --exclude pattern = pattern Avoid -ovalue (no space between) to avoid confusion In particular, be aware of 2-character options. For example: -d -s is (delete, split size) while -ds is (dot size) Usually better to break short options across multiple arguments by = function zip -r -dbdcds 10m -lilalf logfile archive input_directory -ll All args after just "--" arg are read verbatim as paths and not = options. zip zipfile path path ... -- verbatimpath verbatimpath ... Use -nw to also disable wildcards, so paths are read literally: zip zipfile -nw -- "-leadingdashpath" "a[path].c" = "path*withwildcard" You may still have to escape or quote arguments to avoid shell = expansion Wildcards: Internally zip supports the following wildcards: ? (or %% or #, depending on OS) matches any single character * matches any number of characters, including zero [list] matches char in list (regex), can do range [ac-f], all but = [!bf] If port supports [], must escape [ as [[] or use -nw to turn off = wildcards For shells that expand wildcards, escape (\* or "*") so zip can = recurse zip zipfile -r . -i "*.h" Normally * crosses dir bounds in path, e.g. 'a*b' can match 'ac/db'. = If -ws option used, * does not cross dir bounds but ** does For DOS and Windows, [list] is now disabled unless the new option -RE enable [list] (regular expression) matching is used to avoid problems with file paths containing "[" and "]": zip files_ending_with_number -RE foo[0-9].c Include and Exclude: -i pattern pattern ... include files that match a pattern -x pattern pattern ... exclude files that match a pattern Patterns are paths with optional wildcards and match paths as stored = in archive. Exclude and include lists end at next option, @, or end of = line. zip -x pattern pattern @ zipfile path path ... Case matching: On most OS the case of patterns must match the case in the archive, = unless the -ic option is used. -ic ignore case of archive entries This option not available on case-sensitive file systems. On others, = case ignored when matching files on file system but matching against = archive entries remains case sensitive for modes -f (freshen), -U (archive = copy), and -d (delete) because archive paths are always case sensitive. With -ic, all matching ignores case, but it's then possible multiple = archive entries that differ only in case will match. End Of Line Translation (text files only): -l change CR or LF (depending on OS) line end to CR LF = (Unix->Win) -ll change CR LF to CR or LF (depending on OS) line end = (Win->Unix) If first buffer read from file contains binary the translation is = skipped Recursion: -r recurse paths, include files in subdirs: zip -r a path path = ... -R recurse current dir and match patterns: zip -R a ptn ptn = ... Use -i and -x with either to include or exclude paths Path root in archive starts at current dir, so if /a/b/c/file and current dir is /a/b, 'zip -r archive .' puts c/file in archive Date filtering: -t date exclude before (include files modified on this date and = later) -tt date include before (include files modified before date) Can use both at same time to set a date range Dates are mmddyyyy or yyyy-mm-dd Deletion, File Sync: -d delete files Delete archive entries matching internal archive paths in list zip archive -d pattern pattern ... Can use -t and -tt to select files in archive, but NOT -x or -i, so zip archive -d "*" -t 2005-12-27 deletes all files from archive.zip with date of 27 Dec 2005 and later Note the * (escape as "*" on Unix) to select all files in archive -FS file sync Similar to update, but files updated if date or size of entry does not match file on OS. Also deletes entry from archive if no matching file on OS. zip archive_to_update -FS -r dir_used_before Result generally same as creating new archive, but unchanged entries are copied instead of being read and compressed so can be faster. WARNING: -FS deletes entries so make backup copy of archive first Compression: -0 store files (no compression) -1 to -9 compress fastest to compress best (default is 6) -Z cm set compression method to cm: store - store without compression, same as option -0 deflate - original zip deflate, same as -1 to -9 (default) if bzip2 is enabled: bzip2 - use bzip2 compression (need modern unzip) Encryption: -e use standard (weak) PKZip 2.0 encryption, prompt for = password -P pswd use standard encryption, password is pswd Splits (archives created as a set of split files): -s ssize create split archive with splits of size ssize, where ssize = nm n number and m multiplier (kmgt, default m), 100k -> 100 = kB -sp pause after each split closed to allow changing disks WARNING: Archives created with -sp use data descriptors and = should work with most unzips but may not work with some -sb ring bell when pause -sv be verbose about creating splits Split archives CANNOT be updated, but see --out and Copy Mode = below Using --out (output to new archive): --out oa output to new archive oa Instead of updating input archive, create new output archive oa. Result is same as without --out but in new archive. Input archive unchanged. WARNING: --out ALWAYS overwrites any existing output file For example, to create new_archive like old_archive but add newfile1 and newfile2: zip old_archive newfile1 newfile2 --out new_archive Cannot update split archive, so use --out to out new archive: zip in_split_archive newfile1 newfile2 --out out_split_archive If input is split, output will default to same split size Use -s=3D0 or -s- to turn off splitting to convert split to single = file: zip in_split_archive -s 0 --out out_single_file_archive WARNING: If overwriting old split archive but need less splits, old splits not overwritten are not needed but remain Copy Mode (copying from archive to archive): -U (also --copy) select entries in archive to copy (reverse = delete) Copy Mode copies entries from old to new archive with --out and is = used by zip when either no input files on command line or -U (--copy) used. zip inarchive --copy pattern pattern ... --out outarchive To copy only files matching *.c into new archive, excluding foo.c: zip old_archive --copy "*.c" --out new_archive -x foo.c If no input files and --out, copy all entries in old archive: zip old_archive --out new_archive Streaming and FIFOs: prog1 | zip -ll z - zip output of prog1 to zipfile z, converting = CR LF zip - -R "*.c" | prog2 zip *.c files in current dir and stream to = prog2=20 prog1 | zip | prog2 zip in pipe with no in or out acts like zip - = - If Zip is Zip64 enabled, streaming stdin creates Zip64 archives by = default that need PKZip 4.5 unzipper like UnZip 6.0 WARNING: Some archives created with streaming use data descriptors = and should work with most unzips but may not work with some Can use -fz- to turn off Zip64 if input not large (< 4 GB): prog_with_small_output | zip archive -fz- Zip now can read Unix FIFO (named pipes). Off by default to prevent = zip from stopping unexpectedly on unfed pipe, use -FI to enable: zip -FI archive fifo Dots, counts: -db display running count of bytes processed and bytes to go (uncompressed size, except delete and copy show stored = size) -dc display running count of entries done and entries to go -dd display dots every 10 MB (or dot size) while processing = files -dg display dots globally for archive instead of for each file zip -qdgds 10m will turn off most output except dots every 10 MB -ds siz each dot is siz processed where siz is nm as splits (0 no = dots) -du display original uncompressed size for each entry as added -dv display volume (disk) number in format in_disk>out_disk Dot size is approximate, especially for dot sizes less than 1 MB Dot options don't apply to Scanning files dots (dot/2sec) (-q turns = off) Logging: -lf path open file at path as logfile (overwrite existing file) -la append to existing logfile -li include info messages (default just warnings and errors) Testing archives: -T test completed temp archive with unzip before updating = archive -TT cmd use command cmd instead of 'unzip -tqq' to test archive On Unix, to use unzip in current directory, could use: zip archive file1 file2 -T -TT "./unzip -tqq" The return code is checked for success (0 on Unix) Fixing archives: -F attempt to fix a mostly intact archive (try this first) -FF try to salvage what can (may get more but less reliable) Fix options copy entries from potentially bad archive to new archive. -F tries to read archive normally and copy only intact entries, while -FF tries to salvage what can and may result in incomplete entries. Must use --out option to specify output archive: zip -F bad.zip --out fixed.zip Use -v (verbose) with -FF to see details: zip reallybad.zip -FF -v --out fixed.zip Currently neither option fixes bad entries, as from text mode ftp get. Difference mode: -DF (also --dif) only include files that have changed or are new as compared to the input archive Difference mode can be used to create incremental backups. For = example: zip --dif full_backup.zip -r somedir --out diff.zip will store all new files, as well as any files in full_backup.zip = where either file time or size have changed from that in full_backup.zip, in new diff.zip. Output archive not excluded automatically if exists, so either use -x to exclude it or put outside what is being zipped. DOS Archive bit (Windows only): -AS include only files with the DOS Archive bit set -AC after archive created, clear archive bit of included files WARNING: Once the archive bits are cleared they are cleared Use -T to test the archive before the bits are cleared Can also use -sf to save file list before zipping files Show files: -sf show files to operate on and exit (-sf- logfile only) -su as -sf but show escaped UTF-8 Unicode names also if exist -sU as -sf but show escaped UTF-8 Unicode names instead Any character not in the current locale is escaped as #Uxxxx, where x is hex digit, if 16-bit code is sufficient, or #Lxxxxxx if 24-bits are needed. If add -UN=3De, Zip escapes all non-ASCII characters. Unicode: If compiled with Unicode support, Zip stores UTF-8 path of entries. This is backward compatible. Unicode paths allow better conversion of entry names between different character sets. New Unicode extra field includes checksum to verify Unicode path goes with standard path for that entry (as utilities like ZipNote can rename entries). If these do not match, use below options to set what Zip does: -UN=3DQuit - if mismatch, exit with error -UN=3DWarn - if mismatch, warn, ignore UTF-8 (default) -UN=3DIgnore - if mismatch, quietly ignore UTF-8 -UN=3DNo - ignore any UTF-8 paths, use standard paths for = all An exception to -UN=3DN are entries with new UTF-8 bit set (instead of using extra fields). These are always handled as Unicode. Normally Zip escapes all chars outside current char set, but leaves as is supported chars, which may not be OK in path names. -UN=3DEscape escapes any character not ASCII: zip -sU -UN=3De archive Can use either normal path or escaped Unicode path on command line to match files in archive. Zip now stores UTF-8 in entry path and comment fields on systems where UTF-8 char set is default, such as most modern Unix, and and on other systems in new extra fields with escaped versions in entry path and comment fields for backward compatibility. Option -UN=3DUTF8 will force storing UTF-8 in entry path and comment fields: -UN=3DUTF8 - store UTF-8 in entry path and comment fields This option can be useful for multi-byte char sets on Windows where escaped paths and comments can be too long to be valid as the UTF-8 versions tend to be shorter. Only UTF-8 comments on UTF-8 native systems supported. UTF-8 comments for other systems planned in next release. Self extractor: -A Adjust offsets - a self extractor is created by prepending the extractor executable to archive, but internal offsets are then off. Use -A to fix offsets. -J Junk sfx - removes prepended extractor executable from self extractor, leaving a plain zip archive. More option highlights (see manual for additional options and details): -b dir when creating or updating archive, create the temp archive = in dir, which allows using seekable temp file when writing to = a write once CD, such archives compatible with more unzips (could require additional file copy if on another device) -MM input patterns must match at least one file and matched = files must be readable or exit with OPEN error and abort archive (without -MM, both are warnings only, and if unreadable = files are skipped OPEN error (18) returned after archive created) -nw no wildcards (wildcards are like any other character) -sc show command line arguments as processed and exit -sd show debugging as Zip does each step -so show all available options on this system -X default=3Dstrip old extra fields, -X- keep old, -X strip = most -ws wildcards don't span directory boundaries in paths bash$=20
