What is the purpose of a PATH variable?
The PATH variable is an environment variable in operating systems like Unix, Linux, and Windows that specifies a set of directories where executable programs are located. When a user types a command in the terminal or command prompt, the system searches through these directories in the order listed in the PATH variable to find the corresponding executable file. This allows users to run programs without needing to specify their full paths, streamlining the command execution process. Adjusting the PATH variable can help users include custom scripts or software directories for easier access.
