Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In Unix-like computer operating systems, the at command is used to schedule commands to be executed once, at a particular time in the future. More precisely, it reads a series of commands from standard input and collects them into one "at-job" which is carried out at a later date. The at-job inherits the current environment, so that it is executed in the same working directory and with the same environment variables set as when it was scheduled. It differs from cron which is used for recurring executions (e.g. once an hour, every Tuesday, January 1 every year). As with cron, many Unix systems allow the administrator to restrict access to the at command.
