Method Detail

• getEnv

  public static String getEnv(String envVarName)

  This method returns a particular named environment variable from the user's working environment using the getEnv() method to grab that environment.

  Parameters:

  envVarName - The named environment variable to return.

  Returns:

  The environment variable value, as a String.

• getEnv

  public static Properties getEnv()

  This method does exactly the same thing as getEnvUsingWaitFor(), except it uses System.getenv()

  Returns:

  The user's current environment, in a Properties object.

• getEnvUsingWaitFor

  public static Properties getEnvUsingWaitFor()

  Deprecated. 
  This method grabs the current environment using the Linux shell program called env. Unfortunately, this method also uses Process.waitFor(), which seems to hang when folks have weird environment variables and such. A more appropriate method to call is getEnv() because it uses the ExecHelper class, which seems to handle process termination a bit more elegantly.

  Returns:

  A Properites object containing the user's current environment variables.
