Open Zip files on the command line

with support for UTF-8 unicode filenames
and 64 bit zip files, with the free Open Source tool Swiss File Knife for Windows, Mac OS X, Linux and Raspberry Pi.
- download the free Swiss File Knife Base from Sourceforge.
- open the Windows CMD command line, Mac OS X Terminal or Linux shell.
- OS X : type mv sfk-mac-64.exe sfk and chmod +x sfk then ./sfk
- Linux: type mv sfk-linux-64.exe sfk    and chmod +x sfk then ./sfk
  OS X and Linux syntax may differ, check the help within the tool.
SFK The Book - New Productivity Heights.
sfk unzip [-pat mask1 !mask2 ...]

extract .zip file contents.

Unicode marked filename support

sfk unzip supports UTF-8 unicode filenames
if they are marked as such, according to the
zip format standard, or if they are provided
as a zip format UTF-8 name extension.
UTF-8 names are listed with 'u' on extraction.

if foreign language names are extracted,

- they may just show ??? for many characters,
  because the console cannot print them. just
  ignore this and extract it onto an NTFS file
  system, then open the output folder in Windows
  file explorer, to see the correct names.

- other sfk functions may not be able to read
  the extracted files, if they use characters
  outside of your windows codepage.
  i.e. you may be able to extract chinese files
  on a west european windows, but other functions
  like sfk find will then fail to read them.

Unicode unmarked filenames

some old non-standard tools under linux/mac
may produce zip files with unmarked UTF-8 names,
which show no 'u' flag on extraction.
to force extraction as UTF-8, use: sfk unzipuni

Codepage filename support

filenames which are not marked as 'u' UTF-8,
but contain hicodes like umlauts or accents,
are considered to use codepage 850, the system
codepage of your computer. this can be wrong if
the file was created with a different codepage.
you may then try option -fromcode=n with n like
1252 850 852 866 1250 1251 or any other codepage.

64 bit zip file support

sfk unzip can extract 64 bit zip files with sizes
over 2 gb. sfk xe search in zip file contents is
limited to smaller files, for details: sfk help xe

-pat mask   extract only files having mask in their
            path or filename. use -pat !mask
            to exclude paths or filenames.
            -pat \mask\ says the path or file
            must start and end with mask.
-test       check the archive content integrity
            without writing any files.
-verbose    list full details for every file while
            in simulation. prints raw utf-8 or
            codepage filenames from the zip,
            allowing output redirect to file.
            add -full now for more details.
-todir x    write output to folder x
-asdir x    rename top level folder name on extract.
            fails if there are multiple top folders
            in the zip, or files without folders.
-force      continue after errors.
-uauto      detect UTF-8 filenames just by looking
            at their characters. this is not fully
            safe, and should be used only to fix
            bad names from zip files created with
            old non-standard tools.
-noextutf   do not use utf extension field,
            to see the contained oem names.
-keep       keep bad output file even if
            crc check failed.
-offtime    expect file times which are
            one hour off, depending on DST.
            for details see: sfk help offtime
-fromcode=n  set zip filename codepage manually.
            default on this computer is 850.

output chaining
  sfk unzip supports text output chaining.

- Depeche View Pro can directly view the content
  of .zip, .tar.gz and .tar.bz2 files, for quick
  analysis of source packages without extraction.

- SFK XE can search in .zip, .tar.gz and .tar.bz2
  archive contents directly like:

  sfk xfind -arc "/foo*bar/"
    search in all files within

  sfk xfind -arc mydir "/foo*bar/"
    search in all .zip, .tar.gz etc. files
    within folder mydir

  a demo is contained in this binary (it reads
  the first 1000 bytes per archive entry).

- an overview of further zip/unzip tools
  for the command line is available under:

  sfk unzip
    extract whole content of

  sfk unzip -pat mydir .txt
    extract only files with mydir and .txt
    in their path, no matter in which order.

  sfk unzip -pat "foo*bar"
    extract foo1bar, foo2bar but not barfoo.

  sfk unzip -pat \mydir\ !.obj
    extract mydir but not mydir2 or oldmydir
    and exclude all .obj files.

  sfk unzip -verbose >mylist.txt
    write file list with details and raw names
    to mylist.txt, allowing to view this in
    utf-8 capable editors like Notepad++.

  sfk unzip +filter -!test
    extract all from, but do not print
    any names with "test" to terminal.


sfk is a free open-source tool, running instantly without installation efforts. no DLL's,
no registry changes - just get sfk.exe from the zip package and use it (binaries for
windows, linux and mac are included).
