<p>On Unix-like operating systems, <code>at</code> reads a series of commands from <a href="Standard_input" class="mw-redirect" title="Standard input">standard input</a> and collects them into one "at-job" which is carried out at a later date. The job inherits the current environment, so that it is executed in the same <a href="Working_directory" title="Working directory">working directory</a> and with the same <a href="Environment_variable" title="Environment variable">environment variables</a> set as when it was scheduled. It differs from <code><a href="Cron" title="Cron">cron</a></code>, which is used for recurring executions (e.g. once an hour, every Tuesday, January 1 every year). As with <code>cron</code>, many Unix systems allow the administrator to restrict access to the <code>at</code> command. <code>at</code> can be made to mail a user when done carrying out a scheduled job, can use more than one <a href="Job_queue" title="Job queue">job queue</a>, and can read a list of jobs to carry out from a <a href="Computer_file" title="Computer file">file</a> instead of standard input.
