I normally use ; to combine more than one command in a line, but some people prefer && . Is there any difference? For example, cd ~; cd - and cd ~ && cd - seems to make the same thing. What version is more portable, e.g. will be supported by a bash-subset like Android's shell or so? ignar If previous command failed with ; the second one will run. But with && the second one will not run. This is a "lazy" logical "AND" operand between operations. jm666 I'm using && because a long time ago at the nearby computer: root# pwd / root# cd /tnp/test; rm -rf * cd: /tnp/test: No such file or directory ..

I have created a desktop application in Java using NetBeans 6.1 and made a jar file of the application. Now I want to make it automatically start up whenever a client's machine boots up. How do I do that? This installer can create a file with "msi" extension that will behave as regular windows installer. It bundles your jar file and JRE together into single file. The program acts as a "wizard", where you configure all necessary options. Take a look at this product: Advanced Installer Good luck. There are many commercial installers which can do this http://www.advancedinstaller.com/jre-install

I have an application that uses the .NET framework 3.5. I am building this application for a college to help students to study. Most students usually have Windows XP SP2, Windows Vista, or Windows 7. (Sorry Mac users! The Mac version will come out in about 6 months) What version of the .NET framework is installed on Windows XP, Vista, and 7; and will my application run on all of those platforms? Oded From Wikipedia and MSDN : .NET Framework 1.1: Windows Server 2003 .NET Framework 2.0: Windows Server 2003 R2 .NET Framework 3.0: Windows Vista, Windows Server 2008 .NET Framework 3.5: Windows 7,

I have a structure which I create a custom constructor to initialize the members to 0's. I've seen in older compilers that when in release mode, without doing a memset to 0, the values are not initialized. I now want to use this structure in a union, but get errors because it has a non-trivial constructor. So, question 1. Does the default compiler implemented constructor guarantee that all members of a structure will be null initialized? The non-trivial constructor just does a memset of all the members to '0' to ensure a clean structure. Question 2: If a constructor must be specified on the

I am writing a batch script in order to beautify JavaScript code. It needs to work on both Windows and Linux . How can I beautify JavaScript code using the command line tools? Alan Storm First, pick your favorite Javascript based Pretty Print/Beautifier. I prefer the one at http://jsbeautifier.org/ , because it's what I found first. Downloads its file https://github.com/beautify-web/js-beautify/blob/master/js/lib/beautify.js Second, download and install The Mozilla group's Java based Javascript engine, Rhino . "Install" is a little bit misleading; Download the zip file, extract everything,
