This arrangement allows for fallback behavior in different environments, e.g., in an X11 environment, a graphical browser can be used, but in a console environment a terminal-base browser can be used. A %s token may be present to specify where the URL should be placed; otherwise the browser should be launched with the URL as the first argument. Equivalent to the output of the command pwd when called without arguments. The persistence of an environment variable can be session-wide or system-wide. In DOS, OS/2 and Windows command-line interpreters such as COMMAND.COM and CMD.EXE, an environment variable is retrieved by placing a % sign before and after it. The variables can be used both in scripts and on the command line.
The SET command without any arguments displays all environment variables along with their values; SET "0 or more spaces" shows the internal ones too. In CMD.EXE, it is possible to assign local variables that do not leak outside using the SETLOCAL command. The command env displays all environment variables and their values. The command printenv can also be used to print a single variable by giving that variable name as the sole argument to the command.
Is the HOME environment variable normally set in Windows?
Windows 10 environment variables make it incredibly easy to take control of your Windows device and make it run more efficiently. To find and set environment variables in Windows 10, follow the simple steps laid out in this article to get started. Using the reg command allows you to review and unset environment variables directly in the registry.
Open the Advanced tab and click on the Environment Variables button in the System Properties window. Your init file can have any name mentioned in The Emacs Initialization File. In the Advanced section, click the Environment Variables button. Let’s see the steps to set the variable on Windows.

%PATH% (supported since DOS 2.0)This variable contains a semicolon-delimited list of directories in which the command interpreter will search for executable files. Equivalent to the Unix $PATH variable (but some DOS and Windows applications also use the list to search for data files similar to $LD_LIBRARY_PATH on Unix-like systems). It is usually changed via the PATH (or PATH /E under MS-DOS 6.0) command, which also ensures that the directory names are converted into uppercase.
Keep in mind that some of the variables mentioned are not location-specific, including %COMPUTERNAME%, %PATHEXT%, %PROMPT%, %USERDOMAIN%, %USERNAME%. Environment variables play a significant role in setting up the system and shell configuration at the... Here, is the name of the environment variable you want to check. The path is based on programs installed on the computer, so there is no "default path." However, the Windows minimum path is often the path below. In the About window, click the Advanced system settings link under Related settings on the far-right side.
Check A Specific Environment Variable
MiniTool reseller program is aimed at businesses or individual that want to directly sell MiniTool products to their customers. Photo Repair Repair corrupted images of different formats in one go. %NEWFILE%This variable is automatically set to the first parameter given to the CONFIG.SYS directive NEWFILE. %LANGSPEC% (supported since MS-DOS 7.0)This variable is supported by some tools to switch the locale for messages in multilingual issues. %LANG% (supported since MS-DOS 7.0)This variable is supported by some tools to switch the locale for messages in multilingual issues. $LIBPATH or $SHLIB_PATHAlternatives to $LD_LIBRARY_PATH typically used on older Unix versions.
Shell scripts and batch files use environment variables to communicate data and preferences to child processes. They can also be used to store temporary values for reference later in a shell script. However, in Unix, non-exported variables are preferred for this as they don't leak outside the process. Other than this, Windows contains system environment variables created by the operating system, programs, drivers, and more. You cannot tweak the system environment variables, but Windows offers the option to tweak user environment variables’ values.

An environment variable is a dynamic-named value that can affect the way running processes will behave on a computer. They are part of the environment in which a process runs. All these methods should open the list of all the environment variables categorized under separate sections for user and system environment variables. You can create new user variables, edit the existing ones, or delete them using the same dialogue box. You can set up system environment variables using different methods in Windows.
The interpretation of characters in either string differs among systems. When data structures such as lists need to be represented, it is common to use a colon (common on Unix and Unix-like) or semicolon-deliminated list. The JAVA_HOME variable is now visible on the list of all environment variables, with the variable value as the path to the JDK. You can verify it by going to the “edit system variable” settings, and the JAVA_HOME variable should be present right there. This prints out all the environment variables that are set on your system.
I’ll show two of the most common ways to use the environment variables to open the relevant folders. Windows 10 has several such environment variables that make your life easier. Below is the list of all useful environments variable in Windows 10. In the Environment Variables window , highlight the Path variable in the System Variable section and click the Edit button. Eric Raymond is promoting the use of a new environment variable, BROWSER, to complement the existing PAGER, MAILER, and EDITOR variables. This effort is being tested as an experiment in hacking social systems.
As an example, let’s delete the JAVA_HOME variable that we recently tweaked. Select the variable and press “Delete” and “OK” subsequently. The selected variable gets deleted from the list of variables. Click on the environment variable you want to Delete.
%MINUTE%This pseudo-variable returns the minutes of the current time in a 2-digit format with leading zeros, f.e "00".."59". %HOUR24%This pseudo-variable returns the hours of the current time in 24-hour format in a 2-digit format with leading zeros, f.e. It is possible to specify relative directories here, including "." for the current working directory. See also the related environment variable %ENDLIBPATH%. %APPEND% (supported since DOS 3.3)This variable contains a semicolon-delimited list of directories in which to search for files. It is usually changed via the APPEND /E command, which also ensures that the directory names are converted into uppercase.
%DRSYS%Setting this variable to "ON" or "1" will force some versions of the DR-DOS SYS command to work under foreign operating systems instead of displaying a warning. %BETA%This variable contains an optional message displayed by some versions (including DR DOS 3.41) of COMMAND.COM at the startup of secondary shells. Environment variables are local to the process in which they were set. If two shell processes are spawned and the value of an environment variable is changed in one, that change will not be seen by the other. They were introduced in their modern form in 1979 with Version 7 Unix, so are included in all Unix operating system flavors and variants from that point onward including Linux and macOS. Under the System menu, you need to click the Advanced System Settings.
