  Default action is to extract files in list, except those in xlist, to exdir;

  -u  update files, create if necessary      -z  display archive comment

  -x  exclude files that follow (in xlist)   -d  extract files into exdir


modifiers:                                   -q  quiet mode (-qq => quieter)

  -n  never overwrite existing files         -a  auto-convert any text files

  -o  overwrite files WITHOUT prompting      -aa treat ALL files as text

  -j  junk paths (do not make directories)   -v  be verbose/print version info

  -C  match filenames case-insensitively     -L  make (some) names lowercase

  -$  label removables (-$$ => fixed disks)  -V  retain VMS version numbers

  -X  restore ACLs (-XX => use privileges)   -s  spaces in filenames => '_'

                                             -M  pipe through "more" pager

Examples (see unzip.txt for more info):

  unzip data1 -x joe   => extract all files except joe from zipfile data1.zip

  unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer
