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]
In addition to running tasks on scheduled times or specified intervals, Task Scheduler 2.0 also supports calendar and event-based triggers, such as starting a task when a particular event is logged to the event log, or when a combination of events has occurred. Also, several tasks that are triggered by the same event can be configured to run ...
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]
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.
This is a list of notable job scheduler software. Job scheduling applications are designed to carry out repetitive tasks as defined in a schedule based upon calendar and event conditions. This category of software is also called workload automation. Only products with their own article are listed: ActiveBatch; Apache Airflow; Cron; DIET; HTCondor
For clients, the main commands are srun (queue up an interactive job), sbatch (queue up a job), squeue (print the job queue) and scancel (remove a job from the queue).

While users are required to submit the jobs, no other interaction by the user is required to process the batch. Batches may automatically be run at scheduled times as well as being run contingent on the availability of computer resources.
