Descripción:
Perl es un lenguaje de programación que se sitúa a medio camino entre los lenguajes de bajo nivel tipo C o C++ y la programación basada en comandos de shell (Shell Scripting). La facilidad que tiene para crear estructuras de datos y la potencia de su motor de expresiones regulares, lo hace especialmente valioso para un administrador de sistemas, que tendrá en él una herramienta ideal para generar tareas automatizadas, parseo de logs, etc. Este curso es una introducción al lenguaje de programación Perl para principiantes. Presenta las partes más importantes del lenguaje y sienta las bases para un futuro aprendizaje. El Curso de Programación en Perl hace un especial hincapié en aquellas partes que le son más útiles al administrador de sistemas para el desarrollo de su labor.
Objetivo:
Adquirir familiaridad con el lenguaje para poder mejorar su actividad cotidiana, aumentar su productividad, reducir el tiempo empleado en realizar tareas repetitivas y sacar información valiosa del sistema que permita la predicción y solución de problemas.
