问题 I tried things like $_ENV['CLIENTNAME'] == 'Console' but that seems to work on only certain OS's (worked in windows, not linux). I tried !empty($_ENV['SHELL']) but that doesn't work always either...

问题 I have a Node.js project written in Typescript which is expected to run as a CLI, and am having trouble to import a module located out of the node_modules directory using an absolute path (relative paths work fine).

问题 In C, I recalled that I can move the invisible caret around the command line interface screen with respect to the line and character position, meaning I can make the program print any text anywhere on the screen. Do we have such command in Java? For instance, here is a pseudocode in C: int main(){ printf("launching program\n"); moveTo(4,3); //move to line 4 at character index 3 on the screen. printf("AAA"); moveTo(3,0); //move to line 3 at character index 0 on the screen. printf("BBB");
