This document provides an overview of useful commands for Ubuntu Linux, beginning with basic Linux commands and how to get help or more information on commands. It then covers managing software, important keyboard shortcuts, history commands, redirecting input/output, using aliases and environment variables. Additional sections discuss commands for working as a user, such as editing text, searching files, sorting output and more. The document concludes with commands for system administration, including working with partitions, processes, resources, and network interface cards.
Ubuntu is a complete Linux operating system, freely available with both community and professional support.
The Ubuntu community is built on the ideas
software should be available free of charges
software tools should be usable by people in their local language and despite any disabilities and that people should have the freedom to customize and alter their software in whatever way they see fit.
AIX 6.1 introduces several new security features including role-based access control (RBAC) which allows privileged tasks to be delegated to non-privileged users. It also includes an encrypted filesystem that encrypts data for protection and an updated security tool called AIX Security Expert for centralized security management. The document discusses these features and others such as the new secure by default installation option and systems director console.
Linux is a free and open-source operating system based on the Linux kernel, which was created by Linus Torvalds in 1991. It is widely used on servers, desktops, and embedded devices. Major Linux distributions combine the Linux kernel with tools and libraries from the GNU operating system and various application software into a format that is easy to install and use. Linux has gained popularity for its security, reliability, and low cost as well as avoiding vendor lock-in.
El documento resume la evoluci坦n de Linux desde su creaci坦n en 1991 por Linus Torvalds hasta 2007. Algunos hitos clave incluyen el lanzamiento de la versi坦n 1.0 en 1994, el crecimiento de la comunidad de desarrolladores, el soporte de empresas importantes como IBM en 1998, y Dell comenzando a vender computadoras con Ubuntu preinstalado en 2007.
