NAME

unzip - list/test/extract from a ZIP archive file

SYNOPSIS

unzip [ -xecptlvz[qadoUV] ] file[.zip] [filespec...]

ARGUMENTS

file[.zip]  Path of the ZIP archive.  The suffix “.zip” is applied if the file specified does not exist.  Note that self-extracting ZIP files are supported; just specify the “.exe” suffix yourself. 

[filespec]  An optional list of archive members to be processed.  Expressions may be used to match multiple members; be sure to quote expressions that contain characters interpreted by the UNIX shell. See DESCRIPTION (below) for more details. 

OPTIONS

-x,-e  extract files in archive (default--i.e., this flag is optional)
-c     extract files to stdout (“CRT”)
-p     extract files to stdout and no informational messages (for pipes)
-t     test archive contents for validity
-l     list archive contents (short format)
-v     verbose listing of archive contents
-z     display only the archive comment

MODIFIERS

-q     perform operations quietly (up to two q’s allowed)
-a     convert to MS-DOS textfile format (CR LF), Mac format (CR),
         Unix/VMS format (LF), OR from ASCII to EBCDIC, depending on
         your system
-d     recreate directory structure contained in archive
-o     OK to overwrite files without prompting
-U     don’t map filenames to lowercase for selected (uppercase) OS’s
-V     retain file version numbers

DESCRIPTION

unzip will list, test, or extract from a ZIP archive, commonly found on MSDOS systems.  Archive member extraction is implied by the absence of the -c, -p, -t, -l, -v or -z options.  All archive members are processed unless a filespec is provided to specify a subset of the archive members.  The filespec is similar to an egrep expression, and may contain:

∗       matches a sequence of 0 or more characters

?       matches exactly 1 character

\nnn    matches the character having octal code nnn

[...]   matches any single character found inside the brackets; ranges are specified by a beginning character, a hyphen, and an ending character.  If a ’!’ follows the left bracket, then the range of characters matched is complemented with respect to the ASCII character set.
