Cron/Crontab and User Management

User Management :

A user is an entity, in a Linux operating system, that can manipulate files and perform several other operations. Each user is assigned an ID that is unique for each user in the operating system. User Management makes sure the right people get access to the right stuff while keeping the wrong ones out. It helps your team collaborate efficiently and keeps sensitive information safe. After installation of the operating system, the ID 0 is assigned to the root user and the IDs 1 to 999 (both inclusive) are assigned to the system users hence the IDs for local user begins from 1000 onwards.

Cron and Crontab :
