Red Hat Linux Programming (RHD251)

Course Description Schedule
 

Who should attend

Experienced C programmers who want to learn key skills for creating applications and programs on Red Hat Enterprise Linux. This course is also useful for Windows and UNIX programmers migrating their programs to Linux.

Prerequisites

  • Experience in C programming
  • RH200 or equivalent UNIX or Linux workstation user skills for developers
  • Shell scripting in a UNIX or Linux environment
  • Experience with editors such as vi, emacs

Course Objectives

This intensive course rapidly trains programmers to develop applications and programs on Red Hat Enterprise Linux. Over the span of five days, you´ll get hands-on training, concepts, and demonstrations with emphasis on realistic labs and programming exercises.
