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
 -U use escapes for all non-ASCII Unicode -UU ignore any Unicode fields
 -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

Description: Archiver for .zip files
 This is InfoZIP's zip program. It produces files that are fully compatible with the popular PKZIP program; however, the
 command line options are not identical. In other words, the end result is the same, but the methods differ. :-) 
 
 This version supports encryption.

Description: De-archiver for .zip files
 InfoZIP's unzip program. With the exception of multi-volume archives (ie, .ZIP files that are split across several disks
 using PKZIP's /& option), this can handle any file produced either by PKZIP, or the corresponding InfoZIP zip program. 
 
 This version supports encryption.
