ProcessEnvironment

ProcessEnvironment

is an option specifying the initial settings of environment variables to use when executing a process in functions like StartProcess and RunProcess.

Details

  • With the default setting ProcessEnvironment->Inherited, the subprocess will inherit its initial environment from the settings of the parent process (the Wolfram Engine) that calls it.
  • The values of environment variables are typically given in an association.

Examples

Basic Examples  (1)

On Unix systems like Mac OS and Linux, these inputs run the echo process from a system shell to report the value of the environment variable set by the value of the ProcessEnvironment option:

Wolfram Language code: RunProcess[$SystemShell, "StandardOutput", "echo $VAR", ProcessEnvironment -> <|"VAR" -> "valueOfVAR"|>]
Wolfram Language code: RunProcess[{$SystemShell, "-c", "echo $VAR"}, "StandardOutput", ProcessEnvironment -> <|"VAR" -> "valueOfVAR"|>]
