Cron is a job scheduler ubiquitous on Linux and macOS. Cron uses non-interactive shell, so the typical “.bashrc” or “.zshrc” are not processed. It is often useful to use scripts as line-continuation is not allowed in crontab specification. These scripts can source other scripts and set environment variables etc.

Cron can be used from WSL with systemd.
