Further zip tools of possible interest:

Although not discussed here, it should be mentioned that the original Info-ZIP homepageprovides further tools, e.g. for the creation of self-extracting zips, gzip and zipsplit, and of course zip/unzip binaries for many other operating systems.

 
Examples of using zip and unzip:

   zip -r mydir.zip mydir

collects all content from mydir into mydir.zip. actually it is sufficient to say:

   zip -r mydir mydir

which does the same. and with command line completion, you just have to type:

   zip -r my{TAB} my{TAB}

where {TAB} means pressing the TAB key. this is definitely faster than clicking in a GUI.

   unzip -l mydir.zip

lists the contents of mydir.zip without extracting it. this way you see if the .zip contains a path for extraction, e.g.

unzip -l testfiles.zip
Archive:  testfiles.zip
  Length     Date   Time    Name
 --------    ----   ----    ----
        0  02.09.06 13:34   testfiles/
      197  02.09.06 13:34   testfiles/readme.txt
        0  02.09.06 13:34   testfiles/FooBank/
        0  02.09.06 13:34   testfiles/FooBank/BarDriver/
        0  02.09.06 13:34   testfiles/FooBank/BarDriver/include/
      219  02.09.06 13:34   testfiles/FooBank/BarDriver/include/BarBottle.hpp
      244  02.09.06 13:34   testfiles/FooBank/BarDriver/include/BarDriver.hpp
      216  02.09.06 13:34   testfiles/FooBank/BarDriver/include/BarGlass.hpp
      210  02.09.06 13:34   testfiles/FooBank/BarDriver/include/BarMug.hpp

as you see in this case, "unzip testfiles.zip" would create a directory "testfiles", where all content is placed into. so you don't have to create such a directory before.

   unzip -t mydir.zip

tests the contents of mydir.zip without extracting. makes sense after a copy from/to usb stick, to check if all data is still intact. finally,

   unzip mydir.zip

really extracts the zipfile contents. 
 

Example for searching through zip file contents:

   zzfind -pat public class -dir eclipse.zip -file .java

searches all .java files within eclipse.zip for lines with the words "public" AND "class". 
Note that zzfind can also search files in a zip within a zip (nested zips). 
 

How to list nested zip file contents (zips or jars within zips):

For example, if you download the Eclipse SDK and type

   unzip -l eclipse-SDK-3.3.2-win32.zip

you get a listing of less than 2000 files, listing also .jar file names. But how can you also list what is inside the .jar files, without the need to extract everything first?

Download Swiss File Knife Base, then type:

   sfk list -arc eclipse-SDK-3.3.2-win32.zip

This will produce a listing of all files, no matter how deeply nested - in total nearly 70000 lines that can be very long, for example:

The above is the text of a single line (filename), split into 3 lines here for better reading.

As you can see, there is a .class file in a .jar within another .jar within the .zip.

Limitations: SFK may not be able to process very large zip files, zip files with an unusual compression method, or 64 bit zip files. Type sfk help xe to list all limitations. 
 

How to list the contents of all .zip files in all subdirectories:

In the example above, we listed the content of a single zip file. But sfk can also list the contents of all .zip, .jar, .ear, .war and .aar files in a directory tree. type:

   sfk list -arc .

and get the most comprehensive listing of all files, all .zip (.jar etc) file contents 
and even zip contents embedded within other zips. 
 

Flexible file selection for zipping, using sfk:

If you don't want to zip all files of a directory tree, but for example

• files that changed today, or since a date
• files with a specific file extension
• all files except those in subdirectories \save\ and \tmp\
• files that are different compared to another directory

then you have to prepare a file list with the swiss file knife, and send this to the zip tool through zip's option -@ (read file list from standard input).

example: zipping files changed today

   sfk list project -since today | zip -@ update.zip

     adding: project/FooBank/DB/include/DBController.hpp (deflated 34%)
     adding: project/FooBank/DB/source/DBController.cpp (deflated 48%)
     adding: project/FooBank/GUI/include/FooGUI.hpp (deflated 30%)
     adding: project/FooBank/GUI/source/FooGUI.cpp (deflated 42%)

example: including/excluding by filename

   sfk list -dir docs !\tmp\ -file .txt !-save. | zip -@ textfiles.zip

     adding: docs/Formats/01-native-tab-crlf.txt (deflated 49%)
     adding: docs/Formats/02-crlf.txt (deflated 49%)
     adding: docs/Formats/03-native-tab-lf.txt (deflated 49%)
     adding: docs/Formats/04-lf.txt (deflated 49%)
     adding: docs/Formats/05-split-text.txt (deflated 41%)
     adding: docs/Formats/07-filter-src.txt (deflated 41%)
     adding: docs/Formats/08-head-tail.txt (deflated 49%)
     adding: docs/Formats/09 blank file name.txt (stored 0%)
     adding: docs/readme.txt (deflated 24%)

example: comparing directories

we have two directory trees, "docs" and "docs-old". the latter one is a copy of docs, made some days ago. meanwhile, there have been changes in "docs". but what changes?

   sfk list -sincedir docs-old docs

      [add] docs\addendum01.txt
      [add] docs\drivers\spec01.txt
      [add] docs\drivers\spec02.txt
      [add] docs\drivers\spec03.txt
      [dif] docs\FooBank\DB\source\DBController.cpp
      [dif] docs\FooBank\GUI\include\FooGUI.hpp
      [add] docs\tecnotes.txt

so let's collect all these differences into a .zip. notice that zip would be irritated by the [add] and [dif] prefixes in each line, therefore we have to add sfk option -pure:

   sfk list -pure -sincedir docs-old docs

      docs\addendum01.txt
      docs\drivers\spec01.txt
      docs\drivers\spec02.txt
      docs\drivers\spec03.txt
      docs\FooBank\DB\source\DBController.cpp
      docs\FooBank\GUI\include\FooGUI.hpp
      docs\tecnotes.txt

now let's send this to zip:

   sfk list -pure -sincedir docs-old docs | zip -@ update.zip

     adding: docs/addendum01.txt (stored 0%)
     adding: docs/drivers/spec01.txt (stored 0%)
     adding: docs/drivers/spec02.txt (stored 0%)
     adding: docs/drivers/spec03.txt (stored 0%)
     adding: docs/FooBank/DB/source/DBController.cpp (deflated 48%)
     adding: docs/FooBank/GUI/include/FooGUI.hpp (deflated 30%)
     adding: docs/tecnotes.txt (stored 0%)

NTFS and ZIP - execution prevention problem:

i experienced one small problem when using the command-line (un)zip together with NTFS file systems; in short terms, after unzipping ".msi" files, I was unable to install software from these files. windows complained that access to the files was not possible or denied (due to some "execution prevention" mechanism introducted with XP SP2). this was probably because i zipped those files from a FAT partition (maybe even with an older zip tool) and then unzipped them on NTFS. the solution was to copy the files to a partition with FAT(32) file system, e.g. an USB stick, and then to run the installer from there.

NTFS and ZIP - filetime jumps:

another issue concerns filetimes, especially when zipping/unzipping accross FAT and NTFS partitions. in short terms, if you zip files from a FAT partition, then unpack this .zip on an NTFS partition, you always have to expect that the filetimes may be changed globally by a few hours. This is not at all a bug in the zip tool - it's due to the way that NTFS manages filetimes internally. in case you're irritated by this, try the following: 1) remember the filetimes in some directory on an NTFS partition. 2) change the date of your system from summer to winter time, or vice versa 3) have a look again at the filetimes and be shocked: all file times have jumped by one hour! so this is not a zip-specific problem, but it may show up when you compare times listed in a .zip file with those of the files actually created.
