system stability

In Linux, managing system resources not only ensures the smooth operation of individual applications but also maintains the overall stability of the system. The ulimit command is a powerful tool used to control the resources available to the shell and to processes started by it. In this article, we will explore how to configure ulimit values for a script’s child processes through a simple question and answer format, followed by a detailed guide and example. A1: ulimit stands for "user limit" and is a built-in shell command in Linux used to set or report user process resource limits. These limits can control resources such as file size, CPU time, and number of processes.

In the ever-evolving landscape of technology, systems are growing not only in complexity but in their critical roles within business operations. Ensuring these systems are robust and capable of minimal downtime is paramount. Herein lies the brilliance of self-healing systems — automated mechanisms that detect issues and perform necessary actions to restore functionality without human intervention. For Linux environments, especially those managed through the Bash shell, this approach is not only innovative but increasingly essential. Self-healing systems are designed to automatically detect and correct failures to reduce the system downtime and the need for manual intervention.

Introduction: Keeping your Linux system’s packages up to date is generally a recommended practice for security and stability. However, in certain scenarios such as environments that require extensive testing or precise control over when upgrades occur, you might find it necessary to disable automatic updates. This ensures that updates do not interfere with ongoing work, introduce unexpected behaviors, or affect software dependencies unpredictably. Today, we will guide you on how to disable automatic package upgrades for some of the most common package managers in Linux: APT (used by Debian-based distributions), DNF (used by Fedora and its derivatives), and Zypper (used by openSUSE). 1.
