# OS ### Methods #### `os.args()` Returns a list of command line arguments passed to a Ghost script. The first element `[0]` is the script name. ```go os.args() ``` #### `os.clock()` Returns the number of nanoseconds elapsed since January 1, 1970 UTC. January 1st, 1970 at 00:00:00 UTC is referred to as the Unix epoch. Early Unix engineers picked that date arbitrarily because they needed to set a uniform date for the start of time, and New Year's Day, 1970, seemed most convenient. ```go os.clock() // expected value: 1643344902998773000 ``` #### `os.exit()` Causes the current program to exit with the given status code and optional message. Conventionally, code zero indicates success, non-zero an error. The program terminates immediately. For portability, the status code should be in the range `[0, 125]`. ```go os.exit(0, "Process completed successfully") // expected outout: Process completed successfully ``` ### Properties #### `os.name` Returns the name of the current operating system: * `darwin` (macos) * `linux` * `windows` ```go os.name // expected value: darwin ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
