A "running script" is a set of written instructions that a computer program follows to perform specific tasks. It is often used in programming languages like Python, JavaScript, or Bash to automate processes, manipulate data, or control software applications. Running scripts can save time and reduce errors by executing repetitive tasks quickly. When a running script is executed, the computer reads the code line by line and performs the actions specified. This can include anything from simple calculations to complex data analysis. Users can create and modify running scripts to suit their needs, making them a powerful tool in software development and data management.
