The AIR SDK contains a few programs that can be launched from a command line or terminal. Running these programs can often be more convenient when the path to the SDK bin directory is included in the path environment variable.
The information presented here discusses how to set the path on Windows, Mac, and Linux and should serve as a convenient guide. However, computer configurations vary widely, so the procedure does not work for every system. In these cases, you should be able to find the necessary information from your operating system documentation or the Internet.

Setting the PATH on Linux and Mac OS using the Bash shell
When you type a command in a terminal window, the shell, a program that reads what you typed and tries to respond appropriately, must first locate the command program on your file system. The shell looks for commands in a list of directories stored in an environment variable named $PATH. To see what is currently listed in the path, type:
This returns a colon-separated list of directories that should look something like this: https://vacationsven.weebly.com/can-you-download-apps-on-sd-card.html.

If you really want to use the mentioned environment variables in Save dialogs, you could set up expansion short cuts with a tool like TextExpander or Keyboard Maestro which can expand environment variables to typed text and then use the 'Go to Folder' feature (short cut Apple-G) (which is available in Save dialogs) to type the locations from. The process of setting environment variables in the Terminal will be familiar to those with experience with Linux or UNIX. It involves editing files in /etc for global environment variables, and in your home directory for user specific environment variables. Login shell vs non-login shell. Environment variables basically define the behavior of the environment. They can affect the processes ongoing or the programs that are executed in the environment. The region from which this variable can be accessed or over which it is defined is termed as the scope of the variable. Let’s walk through how to list environment and shell variables, and then how to set and add new environment variables at the command line of Mac OS X. Displaying Current Environment & Shell Variables in Mac OS X. To quickly get a list of environmental variables, you can use the following command: printenv. If you want to see a complete list.
Note: If your path contains blank space characters, escape them with a backslash, as in the following:
You can use the echo command again to make sure it worked:
So far so good. You should now be able to type the following commands and get an encouraging response:
If you modified your $PATH variable correctly, the command should report the version of ADT.
There is still one problem, however; the next time you fire up a new terminal window, you will notice that the new entries in the path are no longer there. The command to set the path must be run every time you start a new terminal.
A common solution to this problem is to add the command to one of the start-up scripts used by your shell. On Mac OS, you can create the file, .bash_profile, in the ~/username directory and it will be run every time you open a new terminal window. On Ubuntu, the start-up script run when you launch a new terminal window is .bashrc. Other Linux distributions and shell programs have similar conventions.
To add the command to the shell start-up script:
- Change to your home directory:
- Create the shell configuration profile (if necessary) and redirect the text you type to the end of the file with “cat >>”. Use the appropriate file for your operating system and shell. You can use .bash_profile on Mac OS and .bashrc on Ubuntu, for example.
- Type the text to add to the file:
- End the text redirection by pressing CTRL-SHIFT-D on the keyboard.
- Display the file to make sure everything is okay:
- Open a new terminal window to check the path:Your path additions should be listed.
If you later create a new version of one of the SDKs into different directory, be sure to update the path command in the configuration file. Otherwise, the shell will continue to use the old version.
Setting the Path on Windows
When you open a command window on Windows, that window inherits the global environment variables defined in the system properties. One of the important variables is the path, which is the list of directories that the command program searches when you type the name of a program to run. To see what is currently included in the path when you are using a command window, you can type:
This will show a list of semicolon-separated list of directories that looks something like:

The goal is to add the path to the AIR SDK bin directory to the list so that the command program can find the ADT and ADL tools. Assuming that you have put the AIR SDK at C:SDKsAIR, you can add the proper path entry with the following procedure:
- Open the System Properties dialog from the Control Panel or by right-clicking on the My Computer icon and choosing Properties from the menu.
- Under the Advanced tab, click the Environment Variables button.
- Select the Path entry in the System variables section of the Environment Variables dialog
- Click Edit.
- Scroll to the end of the text in the Variable value field.
- Enter the following text at the very end of the current value:
- Click OK in all the dialogs to save the path.
If you have any command windows open, realize that their environments are not updated. Open a new command window and type the following command to make sure the paths are set up correctly:
Password software pc and mac. If you later change the location of the AIR SDK, or add a new version, remember to update the path variable.
Set Environment Variables Mac Os
If you are new to Mac OS X, you may need to know how to edit your PATH. The good news is that this is an easy task on Mac OS X.
The recommended way is by editing your .bash_profile file. This file is read and the commands in it executed by Bash every time you log in to the system. The best part is that this file is specific to your user so you won’t affect other users on the same system by changing it.
Step 1: Open up a Terminal window (this is in your Applications/Utilites folder by default)
![Mac app environment variables examples Mac app environment variables examples](/uploads/1/3/3/9/133913927/205473107.jpg)
Step 2: Enter the follow commands:
touch ~/.bash_profile; open ~/.bash_profile
This will open the .bash_profile file in Text Edit (the default text editor included on your system). The file allows you to customize the environment your user runs in.
Step 3: Add the following line to the end of the file adding whatever additional directory you want in your path:
export PATH='$HOME/.rbenv/bin:$PATH'
That example would add ~/.rbenv to the PATH. The $PATH part is important as it appends the existing PATH to preserve it in the new value.

Step 4: Save the .bash_profile file and Quit (Command + Q) Text Edit.
Step 5: Force the .bash_profile to execute. This loads the values immediately without having to reboot. In your Terminal window, run the following command.
source ~/.bash_profile
That’s it! Now you know how to edit the PATH on your Mac OS X computer system. You can confirm the new path by opening a new Terminal windows and running:
echo $PATH
You should now see the values you want in your PATH.
[Updated 2/10/2012] The instructions now use the .bash_profile method of editing your PATH. This is preferred as it keeps the changes specific to your user. I also updated the instructions to use Text Edit instead of vim so it is easier for a beginner.
