The PATH environment variable is used by the operating system to specify a list of directories where executable files are located. When you type a command in the terminal, the system searches through these directories in the order they are listed in the PATH variable to find the corresponding executable file.
Key Points:
- Execution: It allows you to run programs without needing to specify their full path.
- Directories: Each directory in the
PATHis separated by a colon (:) on Unix-like systems. - Modification: You can modify the
PATHvariable to include custom directories where you store your scripts or executables.
For example, if you add a directory to your PATH, the system will look in that directory for executables when you run commands.
