The cron command-line utility is a job scheduler on Unix-like operating systems.Users who set up and maintain software environments use cron to schedule jobs [1] (commands or shell scripts), also known as cron jobs, [2] [3] to run periodically at fixed times, dates, or intervals. [4]
anacron is a computer program that performs periodic command scheduling, which is traditionally done by cron, but without assuming that the system is running continuously.. Thus, it can be used to control the execution of daily, weekly, and monthly jobs (or anything with a period of n days) on systems that don't run 24 hours a
VisualCron is a replacement for the Windows Task Scheduler and a similar cron job scheduler in Unix-like operating systems. [1] The software is split into client and server parts, with the former being invoked by the user on demand and the latter always running as a process in the background. [1]
The Berkeley r-commands are a suite of computer programs designed to enable users of one Unix system to log in or issue commands to another Unix computer via TCP/IP computer network. [1] The r-commands were developed in 1982 by the Computer Systems Research Group at the University of California, Berkeley , based on an early implementation of ...
A job scheduler is a computer application for controlling unattended background program execution of jobs. [1] This is commonly called batch scheduling, as execution of non-interactive jobs is often called batch processing, though traditional job and batch are distinguished and contrasted; see that page for details.
STAF incorporates several services that deliver specific functionalities. One of the key services is the STAf eXecution engine, responsible for executing test scripts. [3] Additional services offer features like cron, file system, inter-process communication, e-mail, and hypertext mark-up support, among others.
Custom actions can also be specified using the Task Scheduler API. Task Scheduler keeps a history log of all execution details of all the tasks. [21] Windows Vista uses Task Scheduler 2.0 to run various system-level tasks; [22] consequently, the Task Scheduler service can no longer be disabled (except with a simple registry tweak).
The following example will fetch the src/ directory from a machine named iona using rsync and simultaneously update the libraries on which this program depends, before building the combination. #!/usr/bin/env bash # Parallel update script which makes use of the wait command # Update local copy rsync iona:src/ .
