Visão Geral

Este Curso Unix & Shell Scripting Foundation de 32 horas,fornece uma introdução abrangente a toda a gama de comandos e utilitários do usuário UNIX. Os alunos desenvolverão programação shell, habilidades de edição de vi, proficiência em sed e awk.

Objetivo

Os scripts Unix Shell fornecem uma maneira de automatizar grupos de comandos comumente executados - mas os scripts shell podem fazer muito mais do que isso. Embora muitas tarefas simples sejam automatizadas com pequenos scripts, scripts grandes com centenas de linhas são muito comuns. Esses scripts maiores são escritos por administradores de sistema, administradores de banco de dados, testadores, programadores de utilitários e outros para criar utilitários que são amplamente compostos por comandos UNIX poderosos, como find, sed, awk e centenas de outros.

Publico Alvo

• Unix e Linux, alunos que são novos no ambiente Unix ou Linux
