**//anacron//** is not installed in Slackware by default.((See [[http://slackbuilds.org/repository/13.37/system/anacron/|Slackbuilds.org]] for more information on **//anacron//** on Slackware)) | **//anacron//** no se inastala en Slackware de manera predeterminada.((Ver [[http://slackbuilds.org/repository/13.37/system/anacron/|Slackbuilds.org]] para más información de **//anacron//** en Slackware)) |

**//anacron//** is unique from **//cron//** in the respect that it does not expect the operating system to be running continuously like a 24x7 server. If the time of execution passes while the system is turned off, **//anacron//** executes the command automatically when the machine is turned back on. The reverse is **not** true for **//cron//** - if the computer is turned off during the time of scheduled execution, **//cron//** will not execute the job. Another key difference between **//anacron//** and **//cron//** is the minimum chronological "granularity" - **//anacron//** can only execute jobs by //day//, versus the ability of **//cron//** to execute by the //minute//. Finally, **//anacron//** can __only__ be used by root, while **//cron//** can be used by root and normal users. | **//anacron//** es único respecto a **//cron//** en el sentido de que no espera que el sistema operativo se ejecute continuamente como un servidor 24x7. Si el tiempo de ejecución pasa mientras el sistema está apagado, **//anacron//** ejecuta el comando automáticamente cuando la máquina se enciende de nuevo. Lo contrario **no** es cierto para **//cron//**: si el equipo está apagado a la hora de la ejecución programada, **//cron//** no ejecutará el trabajo. Otra diferencia clave entre **//anacron//** y **//cron//** es la "granularidad" cronológica mínima - **//anacron//** sólo puede ejecutar trabajos cada //día//, frente a la capacidad de **//cron//** de ejecutarlos al //minuto///. Finalmente, **//anacron//** puede __sólo__ ser usado por root, mientras que **//cron//** puede ser usado por root y usuarios normales. |
