To run a program with custom env settings, we do this on Linux $ MYVAR=23 ./foo.py On Windows, the only way I know of is: C:\> set MYVAR=23 C:\> .\foo.py C:\> REM unset MYVAR here (but how?) But can't this done be as an one-liner? ...
I have the following in my .htaccess file: SetEnvIf Host "^example\.com$" myvar=1 <IfDefine myvar> RewriteRule ^(.*)$ index2.php?q=$1 [L,QSA] </IfDefine> As far as I can tell, this should be working properly. However, "myvar" does not appear to get defined when I visit from example.com. I know that I have the mod_setenvif.c enable...
Hi everybody. The problem: elcipse-3.5.0 (Galileo) spits with an error when I try to launch it by clicking its launcher. The curse sound like this: A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following location...

Because you (lovely) people are always so curious about posters' original intents, here's mine: If I'm on a Mac and have a GUI (as opposed to, say, being on an ssh session), I want to set my $EDITOR to mate_wait. (And go with vim otherwise.) And, you have an answer for that. I do too. It even works. Here. Sometimes. So I want you...
I'm pre-packaging a JSP web-app that relies on some file path settings found within web.xml. These settings are unknown at packaging time, because they reference a path the customer will set when deploying the entire application (of which the web-app is a management interface). It seems that the easiest way to avoid tokens and file mod...
What is the difference between using an environment variable, like PATH, as $PATH or ${PATH}? ...
I have a msi package generated by wix that creates a system environment variable by populating the Environment table. <Environment Id="CreateEnvVar" Name="DATADIR" Action="set" System="yes" Part="all" Value="[DATA_DIR]" /> The install successfully creates the environment variable at the system level. This was verified by view...
I have an executable name, like "cmd.exe" and need to resolve it's fully-qualified path. I know the exe appears in one of the directories listed in the PATH environment variable. Is there a way to resolve the full path without parsing and testing each directory in the PATH variable? basically I don't want to do this: foreach (string ...
Greetings, I've got a .pro file that looks like: TEMPLATE = subdirs SUBDIRS = foo bar I want to set a variable, or define, or something in my subdirs .pro file that can be read in both the foo and bar .pro files. I've tried to set an environment variable with: export TEST=something but that does not work, message($$(TEST)) always...
In C programming how do you get the current user and the current working directory. I'm trying to print something like this: asmith@mycomputer:~/Desktop/testProgram:$ (user) (computerName) (current directory) I have the following code, but the username is showing as NULL. Any ideas what I'm doing wrong? void prompt() { pr...
I'm developing a J2EE application that runs in JBoss on a Windows Vista machine, but the application will end up on a Linux machine. Is there a way to pass in the value of an environment variable in a platform independent way? I think (but I'm not sure) the platform-sensitive way would be: -Denv_var=%MY_ENV_VAR% (Windows) -Denv_var=$MY...
I have a PowerShell script that checks that a certain directory is on the PATH (by looking through $env:path). It appears that $env:path is loaded and locally scoped by each application on startup, and that scope is passed on to any child applications. So... if someone opens Firefox, downloads my program, runs it, gets a message that t...
Typically, in Powershell you would use env:VARIABLE = "Some kind of value" But my issue is that I have the name of the variable in a string object. Powershell does not recognize it as a string object and uses the variable name as the name of the environment variable. For example, if I do this: $someVariable = "MY_ENV_VAR" env:$some...
I'm trying to setup .NET (C#) build from command line. Can someone just give me a list of environment variables that I need to set up in the MSDOS prompt before I can run MSBuild.exe from the command line. The path to MSBuild executable would be the most obvious example. I cannot rely on setting variables from MyComputer->Properties->Adv...
In older versions of Windows, it was just open the Control Panel, select the System applet, select the Advanced tab, and then hit the Environment variables button. As a normal user, you could edit the "User variables" but not the "System variables". In Windows Server 2008 R2, if I try to hit the Advanced System settings option in the S...
I created an installer (via WiX) that, as part of the installation, installs a Windows service (written in C#), and starts that Windows service. The service is a FileSystemWatcher and watches for the installation of plug-ins to a specific directory. Originally, it used an environment variable (which pointed to the path I wanted to watc...
Possibly a stupid question: Why can't I set an environment variable with this? os.system('set foo=bar') # on windows I'm aware of os.environ, and that works for me. I'm just confused about why the former doesn't work. ...
I've downloaded C/C++ libraries from Cygwin, and set the environment variables according to the instructions here, in NetBeans. I've also gone through this. Actually I followed the same steps on a different machine and everything worked out fine. But on my machine the associations aren't made. for example: #include<stdio.h> says No suc...
I am trying to invoke a bat file from a perl script as follows: system("call D:/SIP/run_$file_idx.bat"); However I observe that the environment variables in the bat fail to get resolved. If I run the bat file separately from the command prompt it works. Does system() create a new environment and execute bat file in that? What is th...
