An environment variable is a user-definable value that can affect the way running processes will behave on a computer. Environment variables are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the ...
PATH (variable) PATH is an environment variable on Unix-like operating systems, DOS, OS/2, and Microsoft Windows, specifying a set of directories where executable programs are located. In general, each executing process or user session has its own PATH setting.
env is a shell command for Unix and Unix-like operating systems. It is used to either print a list of environment variables or run another utility in an altered environment without having to modify the currently existing environment. Using env, variables may be added or removed, and existing variables may be changed by assigning new values to them.
Global variable. In computer programming, a global variable is a variable with global scope, meaning that it is visible (hence accessible) throughout the program, unless shadowed. The set of all global variables is known as the global environment or global state. In compiled languages, global variables are generally static variables, whose ...
However, quantifying true ESG effects is tricky for several reasons. Firstly, despite the attention devoted to ESG in the literature, there is a real gap between theory and reality. The real effects of changes in investment practices are complicated to quantify because some variables are qualitative rather than quantitative.
TMPDIR. TMPDIR is the canonical environment variable in Unix and POSIX [1] that should be used to specify a temporary directory for scratch space. Most Unix programs will honor this setting and use its value to denote the scratch area for temporary files instead of the common default of /tmp [2] [3] or /var/tmp. [4]
All homeostatic control mechanisms have at least three interdependent components for the variable being regulated: a receptor, a control center, and an effector. [3] The receptor is the sensing component that monitors and responds to changes in the environment, either external or internal. Receptors include thermoreceptors and mechanoreceptors.
Sustainability is a social goal for people to exist on Earth over a long period of time. Definitions of this term are disputed and have varied with literature, context, and time. [2][1] Sustainability usually has three dimensions (or pillars): environmental, economic, and social. [1]
