I've been searching all day for a solution to unzip a file with AutoIt Script. I would like to unzip a file called full.zip to a folder.
This is my last place to turn since I can't find a solution of my own. I have found many solutions made by others; AutoIt3 files containing functions, but the code has issues of which I do not understand, and I'm unable to them copy here because I'm using a screen reader and it doesn't seem to format properly. This is why I can not copy code here.
Does anyone know of a method, tutorial or resource that I can use to unzip a file with AutoIt?
Thanks for any help,
josh.
There are a lot of solutions people have coded. A few examples are the 7zip UDF, Zip.au3, zipfldr UDF. If those are not working for you it is most likely because of small changes to AutoIt, which is usually just #incudes being restructured.
I usually just keep 7za.exe (7-zip's standalone executable, 7-zip can be downloaded from here, and then after installing you can copy the 7za.exe from its program directory).
Then it becomes as simple as a call to RunWait to create the archive:
RunWait("7za.exe a MyNewArchive.zip file1.ext file2.ext ...")
And then to unzip:
RunWait('7za.exe x MyArchive.zip -o"Path\To\MyOutputFolder"')
The 7-zip FAQ also mentions that you can use this exe in your own applications (including commercial ones) provided you mention it in the documentation and provide a link. That means you are ok to use FileInstall(...) to include 7za.exe in the compiled .exe.

Is there a way to scan a .jar file to see each step that the program takes? I just ask because I found a .jar file that will supposedly generate pdf files for me out of Tableau. Unfortunately, I am not familiar with the author of the .jar file and want to make sure that I'm not getting something I don't want.
I also have a similar issue with an .exe file. Is there a way to scan the .exe file to see the steps that it takes?
Yes to both.
Jar is easier, there are a few jar decompilers. Classy Shark is simple to use.
There's also the JetBrains decompiler org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler which makes a little cleaner code, but is more complex to install.
For exe files, it depends on how it was created, if it's .Net, then you can pull it apart pretty easily with ILSpy.
If the exe was written in something else, it gets much more complicated fast.
Background (not necessary to read)
I'm tinkering with MS office files for work (trying to figure out the quickest, easiest way to automate generation of arbitrary-length excel and powerpoint files). Since actual excel files are just zipped archives with .xlsx appended to the filename, I've been unzipping them, editing the xml, rezipping them, and seeing whether OpenOffice can still load them.
However, I've realized (after not too much such testing, thankfully) that, by default, the 'zip' command in bash (or, at least, on my mac) is zipping the files in a format that only requires unzip v1.0 to extract, but normal excel files are zipped in such a way that they require v2.0 to extract. I checked this is a problem by zipping and unzipping an excel file that I knew loaded normally, and then trying to load it. OpenOffice was displeased.
So, I know I need to make the file zip exactly the way excel does, but how to make that happen I'm not sure. I have zip version 3 on my computer, so hopefully if the zip/unzip release cycles are synchronized it should be possible, but I didn't see anything on the man page that immediately seemed to be the solution.
edit:
And zip -9 (which zip -h helpfully says instructs zip to 'zip better') still only requires v1.0 to extract.
Question:
How can I specify in bash that I want zip to zip a file in such a way that it would require unzip v2.0 to unzip?
Often, the reason for an incompatibility between compressed files produced by different versions is the compression algorithm used. If the files were compressed with an algorithm that didn't exist in zip 1.0, that would cause the incompatibility you're seeing.
Look at the man page for your zip utility, see if there's an option to specify the type of compression to use. If there is, look at the existing files created from Excel, and find out what type of compression algorithm they're compressed with, and use that.
On my Linux system, zip reports "This is Zip 2.31 (March 8th 2005), by Info-ZIP.", and it does not have an option for specifying the compression algorithm. On my Windows system, 7-zip does have the option, and it looks like they do have a Mac version available, so you could try that if your zip utility doesn't support that option.
I'm trying to get my website to talk to a friend's program. Think ITunes - one main program with hundreds of thousands of little things installed into it. We don't want to have to create an InstallShield install program for each of those hundreds of thousands of little things.
We have the files grouped into the folder sub-structure.
We have a .REG file for what registry entry needs to be added to see the new folder group.
But is there a way to do a self extracting zip file that reads a registry entry so we know where they installed the original program to be able to dump the new files there as well? I want them to double-click the EXE and click Finish and for everything to work.
(I've been looking into INF and CAB files through IExpress.exe, but haven't found the answer. I remember Package for the Web didn't have an option to read a registry entry, but did let you modify the suggested install path.)
Thanks so much.
Best wishes,
Andrea

Well, yes and no. There are self-extractors that can run a program after extracting all files. DotNetZip, for example, can produce an SFX which can do this.
Just an aside: a normal SFX is just a zip file, with a "stub" executable merged with it. The stub exe can do anything it wants to do, but the most basic thing it does is extract the files in the zip. When you use DotNetZip to produce an SFX, it embeds its particular stub into the zip. That stub knows how to extract files, and also knows how to invoke a program after extracting. You can also produce your own stub that can do other more exotic things.
So you could use an SFX for your purpose. When run, it would extract, then invoke it's extra program. The program could look in the registry, then move or relocate the extracted files to the appropriate place. Then terminate.
For a different twist, the SFX might have just two files: the program-to-run (the one that reads the registry, and another embedded zip. Then when the SFX runs it generates 2 files. Then it invokes the program-to-run, which reads the registry, then unpacks the contained zip and puts the files into the desired place.
Ok, so you could do it.
Should you?
mmm, maybe. This really is an installer, so, you should decide whether you want to use a zip as an installer. Don't forget, if you use an SFX as an installer, there's no good way to uninstall.
Have you tried Inno Setup toolchain? It's a bit better than a bare Self-Extracting ZIP file, it's a setup creation utility. I'm convinced it has got something to put some entry in the Registry, look also at the plugins.
Basically, a self-extracting executable that alters the registry, it's a setup program. So why don't you go for a proper one?

I'm using NSIS to write an installer. I'd like to copy the 'lib' directory contained in a zip. Is it possible to specify that the contents of sampleZip.zip/lib is copied to, say $INSTDIR\lib?
The basic idea of what I want is this, though it obviously doesn't work:
File /r sampleZip.zip\lib\*
Any ideas on how this can be done?
NSIS does not have native support for this, you need to use one of the unzip plugins: NsUnzip, Nsisunz or ZipDLL
Rather than install the plugin, I just copied the libraries I needed using the plugin described at this answer force Maven2 to copy dependencies into target/lib.
Since I was the one building the zip file I wanted to access, I felt this way would be more reliable.
Thanks for the suggestions.
Due to a number of constraints that I won't get into, I have to create a self-extracting ZIP archive on a linux box. The resulting archive should be executable on Windows only. Is this at all possible? If so, what tools would do the job?
Background: when the user downloads a setup package from my linux box, I need that setup package to be pre-populated with a certain key. I only know that key at runtime; my idea was to write a simple .xml file with that key, then zip up the .msi installer with that xml file into a self-extracting archive, and send that file to the browser. If you have alternative ideas on how to make it happen, I'd love to hear those, too
Your answer can be found at the following page: http://ubuntuforums.org/showthread.php?t=847329 Please note that I do not take credit for anything other than using Google and finding something that sounds logically like it would work. I do not guarantee that this information will work, or that you will be able to find the mentioned materials online anymore. I'm just a fan of Google. I hope this helps.
The problem A few days back I had to
create a Win32 compatible
self-extracting ZIP file for a friend.
Sounds easy, right. The problem was
that I didn't have a Windows machine
nearby and I didn't want to install
any archiving programs under Wine.
NOTE: A freeware ZIP program such as
IZArc under Wine can be used to create
a Win32 self-extracting ZIP file too.
That will not be covered by this
howto, sorry.
The "research" Googling around I found
this forum post dated August 2003.
Reading it I found out that
self-extracting ZIP files are nothing
more but a suitable unzip binary
followed by a normal ZIP file. I used
the unzipsfx.exe included in Info-ZIP
UnZip 5.52.
The link on that post worked a few
days ago so I got my hands on the
unzipsfx.exe that I was looking for.
Today, 2nd July 2008 I found the link
dead. After some googling I didn't
find a working link anywhere. I read
the licence a few times and understood
that I can redistribute the original
unzipsfx.exe with a license included.
Please note that the
unzipsfx-552_win32.tar.gz (80 kB) is
not an official Info-ZIP package and
it includes copyrighted software that
I take no credit for. More info in the
Info-ZIP license that is also included
in the tarball. The source code for
the binaries included can be found
here.
The solution
Step one, getting the unzipsfx.exe and
zip package:
* open the Terminal (in Ubuntu press alt+f2 and type gnome-terminal)
* type in the following commands Code:
wget
http://kolmoskone.homelinux.org/~kaja/kamaa/unzipsfx-552_win32.tar.gz
tar zxf unzipsfx-552_win32.tar.gz sudo
apt-get install zip
Step two, creating a ZIP file in
Ubuntu:
* open the file manager (nautilus) and select the files you want to have
zipped
* right click and select Create an archive (or similar). Select a
location for the ZIP file, using your
home directory is the easiest. Select
type .zip. See man zip for information
on how to create a ZIP file in command
line.
Step three, making the ZIP file
self-extracting
* type in the following commands Code:
cat unzipsfx-552_win32/unzipsfx.exe
MYZIPFILE.zip > mysfxfile.exe zip -A
mysfxfile.exe
mysfxfile.exe can now be opened in any
Win32 compatible system (including for
example Windows XP/2000/Vista and even
Wine in Linux) or ANY ZIP COMPATIBLE
archive program such as file-roller in
Ubuntu.
I was able to make this work with unzipsfx. There's a newer version of it available - just came out in April 2009 - version 6.0. Version 5.52 didn't support the critical functionality that I needed - launching a particular setup file after the extraction is completed.
So I downloaded the source files for 6.0. I then modified them to exclude the "prompt to launch stuff" check that is there by default. I recompiled using Visual Studio 2008, tried the steps described in the tutorial above, and it all works like a charm now.
