UnZip 6.00 of 20 April 2009, by Info-ZIP. Maintained by C. Spieler. Send
bug reports using http://www.info-zip.org/zip-bug.html; see README for details.
Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
Default action is to extract files in list, except those in xlist, to exdir;
file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage).
-p extract files to pipe, no messages -l list files (short format)
-f freshen existing files, create none -t test compressed archive data
-u update files, create if necessary -z display archive comment only
-v list verbosely/show version info -T timestamp archive to latest
-x exclude files that follow (in xlist) -d extract files into exdir
modifiers:
-n never overwrite existing files -q quiet mode (-qq => quieter)
-o overwrite files WITHOUT prompting -a auto-convert any text files
-j junk paths (do not make directories) -aa treat ALL files as text
-C match filenames case-insensitively -L make (some) names lowercase
-X restore UID/GID info -V retain VMS version numbers
-K keep setuid/setgid/tacky permissions -M pipe through "more" pager
See "unzip -hh" or unzip.txt for more help. Examples:
unzip data1 -x joe => extract all files except joe from zipfile data1.zip
unzip -p foo | more => send contents of foo.zip via pipe into program more
unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer

Exit status (17) from the manual page

2 | a generic error in the zipfile format was detected. |
3 | a severe error in the zipfile format was detected. |
4 | unzip was unable to allocate memory for one or more buffers during program initialization. |
5 | unzip was unable to allocate memory or unable to obtain a tty to read the decryption password(s). |
6 | unzip was unable to allocate memory during decompression to disk. |
7 | unzip was unable to allocate memory during in-memory decompression. |
8 | [currently not used] |
9 | the specified zipfiles were not found. |
10 | invalid options were specified on the command line. |
11 | no matching files were found. |
50 | the disk is (or was) full during extraction. |
51 | the end of the ZIP archive was encountered prematurely. |
80 | the user aborted unzip prematurely with control-C (or similar) |
81 | testing or extraction of one or more files failed due to unsupported compression methods or unsupported decryption. |
82 | no files were found due to bad decryption password(s). |
Examples (17) from the manual page, untested
unzip letters
To use unzip to extract all members of the archive letters.zip into the current directory and subdirectories below it, creating any subdirectories as necessary:unzip -j letters
To extract all members of letters.zip into the current directory only:unzip -tq letters
To test letters.zip, printing only a summary message indicating whether the archive is OK or not:unzip -tq \*.zip
To test all zipfiles in the current directory, printing only the summaries:unzip -ca letters \*.tex | more
(The backslash before the asterisk is only required if the shell expands wildcards, as in Unix;unzip -p articles paper1.dvi | dvips
To extract the binary file paper1.dvi to standard output and pipe it to a printing program:unzip source.zip "*.[fch]" Makefile -d /tmp
To extract all FORTRAN and C source files--.f, .c, .h, and Makefile--into the /tmp directory:unzip -C source.zip "*.[fch]" makefile -d /tmp
(the double quotes are necessary only in Unix and only if globbing is turned on).unzip -aaCL source.zip "*.[fch]" makefile -d /tmp
To extract any such files but convert any uppercase MS-DOS or VMS names to lowercase and convert the line-endings of all of the files to the local standard (without respect to any files that might be…unzip -fo sources
To extract only newer versions of the files already in the current directory, without querying (NOTE: be careful of unzipping in one timezone a zipfile created in another--ZIP archives other than…unzip -uo sources
To extract newer versions of the files already in the current directory and to create any files not already there (same caveat as previous example):unzip -v
To display a diagnostic screen showing which unzip and zipinfo options are stored in environment variables, whether decryption support was compiled in, the compiler with which unzip was compiled,…unzip -l file.zip
In the last five examples, assume that UNZIP or UNZIP_OPTS is set to -q.unzip -ql file.zip
To do a doubly quiet listing:unzip --ql file.zip
(Note that the .zip'' is generally not necessary.) To do a standard listing:unzip -l-q file.zip
orunzip -l--q file.zip
